Determinantes sociales y salud ocular en pobladores adultos de una comunidad de Ica - 2022 / Social determinants of eye health in adult inhabitants of an Ica community -2022

Objetivo: Identificar los determinantes sociales relacionados a la salud ocular en pobladores adultos de una comunidad de Ica 2022. Materiales y métodos: Se desarrolló una investigación con enfoque cuantitativo de corte transversal, correlacional, donde se incluyó una muestra de 108 pobladores adultos del sector de Santa Bárbara del distrito de Tinguiña en Ica, obtenida por muestreo probabilístico; utilizando dos instrumentos elaborados por las autoras, cada uno fue sometido a validación (p: 0.031) y prueba de confiabilidad (α=0.81; KR-20: 0.83). Resultados: Se identificó como factor biológico sexo femenino en 69.4%, la edad promedio fue de 51.84 ±15.56; el 75% no refiere antecedentes familiares, dentro de los estilos de vida el 94% se expone a una pantalla electrónica, el 65% consume alimentos que protegen la visión y el 62% no toma en cuenta la distancia e iluminación adecuada para la lectoescritura; el 91% refirió recibir una atención sanitaria inadecuada, el 71% afirma que su situación económica no les permite atender su salud, 80% no accede a una consulta oftalmológica, ni cubren su tratamiento; asimismo, el 94% de los pobladores no cuidan su salud ocular. Conclusión: Los determinantes sociales de la salud ocular identificados corresponden a la deficiente situación socioeconómica (rs = 0.212; p: 0.027); el ingreso familiar deficiente para la atención de salud (rs = 0.25; p: 0.009); no cubrir la consulta oftalmológica (rs = 0.24; p: 0.012); ni el tratamiento que esta genera (rs = 0.213; p: 0.02).

Factors associated with vision-related quality of life in Brazilian patients with glaucoma / Fatores associados à qualidade de vida relacionada à visão em pacientes brasileiros com glaucoma

ABSTRACT Purpose: To evaluate the impact of visual acuity, visual field damage, and other factors on the quality of life in Brazilian patients with glaucoma. Methods: This cross-sectional prospective study involved 49 patients with glaucoma enrolled based on the presence of reproducible standard automated perimetry defects in at least one eye at the time of evaluation. A detailed ophthalmologic examination was performed on each patient. All patients had reproducible standard automated perimetry and completed an NEI VFQ-25 questionnaire. The associations of the quality of life scores to the best-corrected visual acuity and the visual field loss of the better and worse eyes were investigated. Results: The mean quality of life score of the patients was 58.8 ± 18.7 units. The highest and lowest mean values (85.0 ± 24.2 and 37.5 ± 36.5 units) were observed in the "Social Functioning Subscale" and "Driving Subscale," respectively. Patients with advanced glaucoma (mean deviation <-12 dB) in the worse eye had significantly lower quality of life scores (p=0.007). There was a significant correlation between the quality of life scores and the visual acuity of the better and worse eyes (r2=13%, p=0.010 and r2=32%, p<0.001, respectively). There was also a significant correlation between the quality of life scores and standard automated perimetry mean deviation of the better and worse eyes (r2=13%, p=0.023 and r2=47%, p<0.001, respectively). In a multivariate model containing so­cioeconomic and comorbidity indices, quality of life remained significantly related to the standard automated perimetry mean deviation of the better and worse eyes (r2=23%, p=0.29 and r2=49%, p<0.001, respectively) as well as to the visual acuity of the better and worse eyes (r2=18%, p=0.017 and r2=40%, p<0.001, respectively). Conclusion: The standard automated perimetry mean deviation and the visual acuity of the better and worse eyes were associated with lower quality of life in Brazilian patients with glaucoma. Quality of life was mostly highly associated with the standard automated perimetry mean deviation of the worse eye.

RESUMO Objetivo: Avaliar o impacto da acuidade visual, danos no campo visual e outros fatores na qualidade de vida em pacientes brasileiros com glaucoma. Métodos: Este foi um estudo transversal prospectivo incluindo 49 pacientes com glau­coma selecionados com base na presença de defeitos por perimetria automatizada padrão reprodutíveis em pelo menos um olho no momento da avaliação. Um exame oftalmológico detalhado foi realizado em cada paciente. Todos os pacientes possuíam perimetria automatizada padrão reprodutível e preencheram um questionário NEI VFQ-25. As associações dos escores de qualidade de vida à acuidade visual melhor corrigida e à perda de campo visual dos melhores e piores olhos foram investigadas. Resultados: A média dos escores de qualidade de vida dos pacientes foi de 58,8 ± 18,7 unidades. Os maiores e menores valores médios (85,0 ± 24,2 e 37,5 ± 36,5 unidades) foram observados nas subescalas "Social Functioning Subscale" e "Driving Subscale", respectivamente. Pacientes com glaucoma avançado (desvio médio <-12 dB) no pior olho tiveram escores de qualidade de vida significativamente menores (p=0,007). Houve correlação significativa entre escores de qualidade de vida e a acuidade visual dos olhos melhores e piores (r2=13%; p=0,010 e r2=32%; p<0,001; respectivamente). Houve também uma correlação significativa entre os escores de qualidade de vida e desvios médios da perimetria automatizada padrão dos olhos melhores e piores (r2=13%; p=0,023 e r2=47%; p<0,001; respectivamente). Em um modelo multivariado contendo dados socioeconômicos e de comorbidades, a qualidade de vida permaneceu significativamente relacionada ao desvio médio padrão da perimetria automatizada do olho melhor e pior (r2=23%; p=0,29 e r2=49%; p<0,001, respectivamente) bem como para a acuidade visual do olho melhor e pior (r2=18%; p= 0,017 e r2=40%; p<0,001, respectivamente). Conclusão: O desvio padrão da perimetria automatizada padrão e a acuidade visual dos olhos melhor e pior foram associados à menor qualidade de vida em pacientes brasileiros com glaucoma. A qualidade de vida foi em grande parte altamente associada ao desvio padrão da perimetria automatizada padrão do pior olho.

Resolubility of eye care in a secondary care center: a quantitative approach / Resolubilidade do cuidado oftalmológico em um centro de atendimento secundário: abordagem quantitativa

ABSTRACT Objective To evaluate the resolubility of ophthalmologic care in an integrated health center. Methods This was a cross-sectional study including 816 patients who were attended from November 2013 to November of 2015. Data were collected from a medical consultation database and patients' medical records. Results The majority of participants were women, non-diabetic, and had high school education. The main cause of referral for ophthalmologic evaluation was the consultation with a specialist, the waiting time for consultation was shorter for non-diabetic patients. Conclusion This Integrated health center presented, partial resolubility conditions to meet the ophthalmologic needs of users of the Brazilian Unified Health System. Eye care needs to be reorganized particularly by consider the priority cases of those at ophthalmological risk, and referrals should be done to the adequate care level and on time to guarantee resolubility.

RESUMO Objetivo Avaliar a resolubilidade do cuidado oftalmológico em um centro integrado de saúde. Métodos Trata-se de estudo transversal realizado com 816 pacientes atendidos no período de novembro de 2013 a novembro de 2015. Os dados foram coletados consultando-se o banco de dados institucional e os prontuários. Resultados A maioria dos participantes era não diabética, do sexo feminino, e com Nível Médio de ensino. A principal causa de solicitação de avaliação oftalmológica foi a consulta com o especialista, cujo tempo de espera foi menor para os não diabéticos. Conclusão Este centro integrado de saúde apresentou, em parte, condições de resolubilidade para atender as necessidades oftalmológicas dos usuários do Sistema Único de Saúde, mas notou-se necessidade de reorganização deste cuidado, considerando prioridades baseadas em critérios de risco oftalmológico, conferindo que o encaminhamento ao nível de atenção deve ser capaz de propiciar, em tempo, a resolubilidade.

Barriers between community screening for visual problems and treatments in a tertiary center

ABSTRACT OBJECTIVE To evaluate the effectiveness of mobile ophthalmic unit screenings and to investigate barriers between community care and resolution of the problem at a tertiary center. METHODS This prospective study evaluated a convenience sample from 10 municipalities in São Paulo State, Brazil. Patients were assessed in the municipality by a mobile ophthalmic unit and underwent a complete ophthalmic consultation. Patients were referred as warranted to a tertiary hospital. RESULTS The mobile ophthalmic unit screened 1,928 individuals and 714 (37%) were referred. The mean age of the referred patients was 57.12 (SD = 19.5) years with best corrected visual acuity of 0.37 (SD = 0.36) logMAR. Forty-seven (6.6%) patients were blind and 185 (26.5%) were visually impaired. Cataracts (44.7%) and pterygium (14.7%) accounted for most referrals. Of those referred, 67.1% presented to the tertiary center. The diagnosis by the mobile ophthalmic unit corresponded to the one by the tertiary center in 88.5% of the cases. There were a significantly higher number of blind and visually impaired persons among those who presented to the hospital. There was a significantly greater attendance among patients living in more distant municipalities from the reference center with a higher number of inhabitants and a greater number of ophthalmologists in the cities of origin (p < 0.05, all comparisons). Complete treatment was performed in 65.6% of patients, and loss to follow-up was the main cause of incomplete treatment in 50.7% of patients. A total of 313 cataract surgeries were performed, which reduced the number of blind patients from 20 to 2 and of visually impaired individuals from 87 to 2 (p < 0.001). CONCLUSIONS Only 37% of the patients assessed by a mobile ophthalmic unit required referral to a tertiary hospital. Among the referred patients, 67.1% presented to the hospital, and complete resolution after treatment was approximately 65.5%. There was a significant improvement in visual acuity and a reduction in the prevalence of blindness and visual impairment postoperatively.

Ergophthalmology in accounting offices: the computer vision syndrome (CVS) / Ergoftalmologia em escritórios de contabilidade: a síndrome visual do computador (SVC)

Abstract Purpose: This study aimed to determine the presence of the symptoms of computer vision syndrome (CVS) accounting office employees. Methods: The research tools used were a questionnaire based on the set of symptoms of CVS rated by Likert scale (1-5) and workplace observations based on Ergonomic Workplace Analysis (EWA). Results: The participants who worked with a viewing angle of less than 10º relative to the screen had more symptoms, particularly of pain in the back of the neck and back (p = 0.0460). The participants who used lighting other than 450 and 699 lux reported significant headache (p = 0.0045) and dry eye (p = 0.0329) symptoms. Younger workers had more headaches (p = 0.0182), and workers with fewer years of employment had more headaches and dry eyes symptoms (p = 0.0164 and p = 0.0479, respectively). A total of 37% of the participants reported a lack of guidance regarding prevention and painful symptoms in the back of the neck and back (p = 0.0936). Conclusion: Younger participants with fewer years of employment, who had not received information regarding proper computer use, who did not use lighting between 450 and 699 lux or who worked with viewing angles of less than 10º had more computer vision syndrome symptoms.

Resumo Objetivo: Este trabalho objetivou averiguar a presença dos sintomas da Síndrome Visual dos Computadores (SVC) trabalhadores de escritórios de contabilidade. Métodos: Como instrumentos de pesquisa utilizou-se um questionário baseado no conjunto de sintomas da SVC, avaliado por Escala Likert (1-5), e foram realizadas observações no local de trabalho baseadas na Avaliação Ergonômica de Postos de Trabalho. Resultados: Os participantes que trabalhavam com o ângulo de visão menor do que 10º em relação à tela foram os que apresentaram mais sintomas sobretudo de dor na parte posterior do pescoço e nas costas (p=0,0460). Aqueles que usavam iluminação diferente de 450 e 699 lux reportaram sintomas significativos para dor de cabeça (p=0,0045) e ressecamento ocular (p=0,0329). Os mais jovens apresentaram mais dor de cabeça (p=0,0182) e aqueles com menor tempo de trabalho mais sintomas de dor de cabeça e ressecamento ocular (respectivamente p=0,0164 e p=0,0479). A falta de recebimento de orientações sobre prevenção foi confirmada por 37% participantes que referiram mais sintomas de dor na parte posterior do pescoço e nas costas (p=0,0936). Conclusão: Os participantes mais jovens, com menor tempo de trabalho, que não haviam recebido informações sobre o uso de computador, não utilizavam iluminação entre 450 e 699 lux ou trabalhavam com o ângulo de visão menor do que 10º apresentaram mais sintomas da síndrome visual do computador.

A comparative assessment of avoidable blindness and visual impairment in seven Latin American countries: prevalence, coverage, and inequality / Una evaluación comparativa de la ceguera y la deficiencia visual evitables en siete países latinoamericanos: prevalencia, cobertura y desigualdades

Objective. To conduct a comparative analysis of social inequalities in eye health and eye health care and generate baseline evidence for seven Latin American countries as a benchmarking exercise for monitoring progress toward three goals of the regional Plan of Action for the Prevention of Blindness and Visual Impairment: increasing eye health service coverage, minimizing barriers, and reducing eye health-related disease burden. Methods. Results from cross-sectional eye health surveys conducted in six Latin American countries (Argentina, El Salvador, Honduras, Panama, Peru, and Uruguay) from 2011 to 2013 and recently published national surveys in Paraguay were analyzed. The magnitude of absolute and relative inequalities between countries in five dimensions of eye health across the population gradient defined by three equity stratifiers (educational attainment, literacy, and wealth) were explored using standard exploratory data analysis techniques. Results. Overall prevalence of blindness in people 50 years old and older varied from 0.7% (95% CI: 0.4-1.0) in Argentina to 3.0% (95% CI: 2.3-3.6) in Panama. Overall prevalence of visual impairment (severe plus moderate) varied from 8.0% (95% CI: 6.5-11.0) in Uruguay to 14.3% (95% CI: 13.9-14.7) in El Salvador. The main reported cause of blindness was unoperated cataract and most cases of visual impairment were caused by uncorrected refractive error. Three countries had cataract surgical coverage of more than 90% for blind persons, and two-thirds of cataract-operated patients had good visual acuity. Conclusions. Blindness and moderate visual impairment prevalence were concentrated among the most socially disadvantaged, and cataract surgical coverage and cataract surgery optimal outcome were concentrated among the wealthiest. There is a need for policy action to increase services coverage and quality to achieve universality.

Objetivo. Realizar un análisis comparativo de las desigualdades sociales en materia de salud ocular y atención oftálmica, y generar datos probatorios de referencia de siete países latinoamericanos como un ejercicio de evaluación comparativa para vigilar el progreso hacia tres metas del Plan de Acción para la Prevención de la Ceguera y la Deficiencia Visual Evitables: el aumento de la cobertura de los servicios de salud ocular, la reducción al mínimo de las barreras y la disminución de la carga de morbilidad relacionada con la salud ocular. Métodos. Se analizaron los resultados de las encuestas transversales de salud ocular realizadas en seis países latinoamericanos (Argentina, El Salvador, Honduras, Panamá, Perú y Uruguay) desde el 2011 al 2013, y las encuestas nacionales del Paraguay recientemente publicadas. Mediante el empleo de técnicas ordinarias de análisis exploratorio de datos, se investigó la magnitud de las desigualdades absolutas y relativas entre países en cinco dimensiones de la salud ocular a través del gradiente poblacional definido por tres variables de estratificación de equidad (logro educativo, alfabetización y riqueza). Resultados. La prevalencia general de la ceguera en personas de 50 años de edad o mayores varió de 0,7% (intervalo de confianza (IC) de 95%: 0,4-1,0) en Argentina a 3,0% (IC95%: 2,3-3,6) en Panamá. La prevalencia general de la deficiencia visual (grave y moderada) varió de 8,0% (IC95%: 6,5-11,0) en Uruguay a 14,3% (IC95%: 13,9-14,7) en El Salvador. La principal causa notificada de ceguera fue la catarata no operada, mientras que la mayor parte de los casos de deficiencia visual fueron causados por un error de refracción no corregido. Tres países tenían una cobertura quirúrgica de la catarata de más de 90% para las personas ciegas, mientras que dos terceras partes de los pacientes operados de cataratas mostraban una buena agudeza visual. Conclusiones. Las prevalencias de la ceguera y la deficiencia visual moderada se concentraban en las personas más desfavorecidas socialmente, mientras que la cobertura quirúrgica de la catarata así como los resultados óptimos de esta intervención se concentraban en los más adinerados. Son necesarias acciones políticas para aumentar la cobertura y la calidad de los servicios con objeto de alcanzar la universalidad.

Encuesta de ceguera y deficiencia visual evitable en Panamá / Survey on avoidable blindness and visual impairment in Panama

OBJETIVO: Determinar la prevalencia de ceguera y deficiencia visual en adultos de 50 años o más de Panamá, identificar sus principales causas y caracterizar la oferta de servicios de salud ocular. MÉTODOS: Estudio poblacional transversal mediante la metodología estándar de evaluación rápida de ceguera evitable. Se seleccionaron 50 personas de 50 años o más de cada uno de 84 conglomerados escogidos mediante muestreo aleatorio representativo de todo el país. Se evaluó la agudeza visual (AV) mediante una cartilla de Snellen y el estado del cristalino y del polo posterior por oftalmoscopía directa. Se calculó la cobertura de cirugía de catarata y se evaluó su calidad, así como las causas de tener AV < 20/60 y las barreras para acceder al tratamiento quirúrgico. RESULTADOS: Se examinaron 4 125 personas (98,2% de la muestra calculada). La prevalencia de ceguera ajustada por la edad y el sexo fue de 3,0% (intervalo de confianza de 95%: 2,3-3,6). La principal causa de ceguera fue la catarata (66,4%), seguida del glaucoma (10,2%). La catarata (69,2%) fue la principal causa de deficiencia visual (DV) severa y los errores de refracción no corregidos fueron la principal causa de DV moderada (60,7%). La cobertura quirúrgica de catarata en personas fue de 76,3%. De todos los ojos operados de catarata, 58,0% logró una AV < 20/60 con la corrección disponible. CONCLUSIONES: La prevalencia de ceguera en Panamá se ubica en un nivel medio con respecto a la encontrada en otros países de la Región. Es posible disminuir este problema, ya que 76,2% de los casos de ceguera y 85,0% de los casos de DV severa corresponden a causas evitables.

OBJECTIVE: Determine prevalence of blindness and visual impairment in adults aged > 50 years in Panama, identify their main causes, and characterize eye health services. METHODS: Cross-sectional population study using standard Rapid Assessment of Avoidable Blindness methodology. Fifty people aged > 50 years were selected from each of 84 clusters chosen through representative random sampling of the entire country. Visual acuity was assessed using a Snellen chart; lens and posterior pole status were assessed by direct ophthalmoscopy. Cataract surgery coverage was calculated and its quality assessed, along with causes of visual acuity < 20/60 and barriers to access to surgical treatment. RESULTS: A total of 4 125 people were examined (98.2% of the calculated sample). Age- and sex-adjusted prevalence of blindness was 3.0% (95% CI: 2.3-3.6). The main cause of blindness was cataract (66.4%), followed by glaucoma (10.2%). Cataract (69.2%) was the main cause of severe visual impairment and uncorrected refractive errors were the main cause of moderate visual impairment (60.7%). Surgical cataract coverage in individuals was 76.3%. Of all eyes operated for cataract, 58.0% achieved visual acuity < 20/60 with available correction. CONCLUSIONS: Prevalence of blindness in Panama is in line with average prevalence found in other countries of the Region. This problem can be reduced, since 76.2% of cases of blindness and 85.0% of cases of severe visual impairment result from avoidable causes.

Prevalence of visual impairment in El Salvador: inequalities in educational level and occupational status / Prevalencia de deficiencia visual en El Salvador: desigualdades según el nivel educativo y la situación laboral

OBJECTIVE: To examine the prevalence of blindness, visual impairment, and related eye diseases and conditions among adults in El Salvador, and to explore socioeconomic inequalities in their prevalence by education level and occupational status, stratified by sex. METHODS: Based upon the Rapid Assessment of Avoidable Blindness (RAAB) methodology, this nationwide sample comprised 3 800 participants (3 399 examined) ≥ 50 years old from 76 randomly selected clusters of 50 persons each. The prevalence of blindness, visual impairment and related eye diseases and conditions, including uncorrected refractive error (URE), was calculated for categories of education level and occupational status. Multiple logistic regression models were fitted to calculate odds ratios (ORs) and 95% confidence intervals (CIs) and stratified by sex. RESULTS: Age-adjusted prevalence was 2.4% (95% CI: 2.2-2.6) for blindness (men: 2.8% (95% CI: 2.5-3.1); women: 2.2% (95% CI: 1.9-2.5)) and 11.8% (95% CI: 11.6-12.0) for moderate visual impairment (men: 10.8% (95% CI: 10.5-11.1); women: 12.6% (95% CI: 12.4-12.8)). The proportion of visual impairment due to cataract was 43.8% in men and 33.5% in women. Inverse gradients of socioeconomic inequalities were observed in the prevalence of visual impairment. For example, the age-adjusted OR (AOR) was 3.4 (95% CI: 2.0-6.4) for visual impairment and 4.3 (95% CI: 2.1-10.4) for related URE in illiterate women compared to those with secondary education, and 1.9 (95% CI: 1.1-3.1) in cataract in unemployed men. CONCLUSIONS: Blindness and visual impairment prevalence is high in the El Salvador adult population. The main associated conditions are cataract and URE, two treatable conditions. As socioeconomic and gender inequalities in ocular health may herald discrimination and important barriers to accessing affordable, good-quality, and timely health care services, prioritization of public eye health care and disability policies should be put in place, particularly among women, the unemployed, and uneducated people.

OBJETIVO: Analizar la prevalencia de la ceguera, la deficiencia visual, y las enfermedades y afecciones oculares relacionadas en adultos de El Salvador, y explorar las desigualdades socioeconómicas en cuanto a su prevalencia según el nivel educativo y la situación laboral, estratificados por sexos. MÉTODOS: Se adoptó el método de Evaluación Rápida de la Ceguera Evitable, y se escogió una muestra a escala nacional de 3 800 participantes (de ellos se examinaron 3 399) de 50 años de edad o mayores, pertenecientes a 76 agrupamientos seleccionados aleatoriamente y constituidos por 50 personas cada uno. Se calculó la prevalencia de la ceguera, la deficiencia visual y las enfermedades y afecciones oculares relacionadas, incluido el error de refracción no corregido, según las diferentes categorías de nivel educativo y situación laboral. Se emplearon modelos de regresión logística múltiple para calcular las razones de posibilidades (OR) y los intervalos de confianza (IC) de 95%, y se estratificaron por sexos. RESULTADOS: La prevalencia ajustada por edad fue de 2,4% (IC de 95%: 2,2-2,6) para la ceguera (hombres: 2,8% [IC de 95%: 2,5-3,1]; mujeres: 2,2% [IC de 95%: 1,9-2,5]) y de 11,8% (IC de 95%: 11,6-12,0) para la deficiencia visual moderada (hombres: 10,8% [IC de 95%: 10,5-11,1]; mujeres: 12,6% [IC de 95%: 12,4-12,8]). La proporción de deficiencias visuales debidas a catarata fue de 43,8% en los hombres y de 33,5% en las mujeres. En la prevalencia de la deficiencia visual se observaron gradientes inversos de desigualdades socioeconómicas. Por ejemplo, la OR ajustada por edad fue de 3,4 (IC de 95%: 2,0-6,4) para la deficiencia visual y de 4,3 (IC de 95%: 2,1-10,4) para el error de refracción no corregido relacionado en las mujeres analfabetas, en comparación con las que tenían un nivel de educación secundaria, y fue de 1,9 (IC de 95%: 1,1-3,1) para la catarata en los hombres desempleados. CONCLUSIONES: La prevalencia de ceguera y deficiencia visual es alta en la población adulta de El Salvador. Las principales afecciones asociadas son la catarata y el error de refracción no corregido, ambas tratables. Puesto que las desigualdades socioeconómicas y de género en materia de salud ocular pueden ser indicativas de discriminación y de la existencia de barreras importantes para obtener acceso a servicios de atención de salud asequibles, de buena calidad y oportunos, es preciso dar prioridad a la atención oftalmológica pública y a las políticas dirigidas a corregir la discapacidad, en particular en las mujeres y en las personas desempleadas y sin formación.

Encuestas nacionales de ceguera y deficiencia visual evitables en Argentina, El Salvador, Honduras, Panamá, Perú y Uruguay / National surveys of avoidable blindness and visual impairment in Argentina, El Salvador, Honduras, Panama, Peru, and Uruguay

OBJETIVO: Describir la justificación y metodología usadas en la Evaluación Rápida de Ceguera Evitable empleada para efectuar encuestas a nivel nacional entre 2011 y 2013 en Argentina, El Salvador, Honduras, Panamá, Perú y Uruguay. MÉTODOS: La encuesta se dirige a personas de 50 años o más, lo que reduce al mínimo los requisitos de tamaño de la muestra, que oscila entre 2 000 y 5 000 personas. Se emplean sistemas simples de muestreo y técnicas de examen; el análisis de datos es automático y no requiere de un experto en estadística. Es relativamente económica, ya que no toma mucho tiempo, no requiere equipos oftalmológicos costosos y puede ser llevada a cabo por el personal local. Los informes son generados mediante el propio programa informático de la evaluación. RESULTADOS: Los indicadores generados son la prevalencia de la ceguera y la deficiencia visual severa y moderada (discriminadas por causas evitables y cataratas); la prevalencia de afaquia o pseudofaquia; la cobertura de la cirugía de cataratas; el resultado visual de las cirugías de cataratas; las causas de resultados malos; las barreras de acceso a la cirugía de cataratas; y los indicadores de servicio de la cirugía de cataratas. Los resultados de cada una de las encuestas serán publicados de manera secuencial en números sucesivos de la revista, y en un artículo final de resumen se hará un análisis de los resultados en su conjunto y comparativo entre las encuestas y con aquellas publicadas anteriormente, que aportará un estado de la situación actual en ese grupo de países. CONCLUSIONES: La Evaluación Rápida de Ceguera Evitable es una metodología sólida, sencilla y económica para determinar la prevalencia de ceguera y deficiencia visual y la cobertura y calidad de los servicios de salud ocular, y representa una herramienta muy valiosa para medir el progreso de los programas de prevención de la ceguera y su impacto en la población.

OBJECTIVE: Describe the rationale and methodology of the Rapid Assessment of Avoidable Blindness applied in surveys at the national level in 2011-2013 in Argentina, El Salvador, Honduras, Panama, Peru, and Uruguay. METHODS: The survey includes individuals aged 50 years and older, minimizing required sample sizes, which vary from 2 000 to 5 000 people. It uses straightforward sampling and examination techniques, and data analysis is automatic and does not require a statistician. It is relatively inexpensive, as it does not take a long time, does not require expensive ophthalmic equipment, and can be carried out by local staff. Reports are generated by the assessment software package. RESULTS: Indicators measured are prevalence of blindness and of moderate and severe visual impairment (broken down into avoidable causes and cataracts); prevalence of aphakia or pseudophakia; cataract surgical coverage; visual outcome of cataract surgeries; causes of poor outcomes; access barriers to cataract surgery; and cataract surgery service indicators. Results of each survey will be published sequentially in successive issues of the Journal, and a final summary article will analyze results as a whole and in comparison with the other surveys in this group and with those previously published, which will provide a current picture of the situation in this group of countries. CONCLUSIONS: The Rapid Assessment of Avoidable Blindness is a robust, simple, and inexpensive methodology to determine prevalence of blindness and visual impairment as well as eye health service coverage and quality. It is a very valuable tool for measuring progress by blindness prevention programs and their impact on the population.

Rapid assessment of avoidable blindness in Uruguay: results of a nationwide survey / Evaluación rápida de la ceguera evitable en Uruguay: resultados de un estudio a escala nacional

OBJECTIVE: To investigate and describe the prevalence and causes of blindness and moderate and severe visual impairment in older adults living in Uruguay. METHODS: All individuals aged ≥ 50 years old living in randomly selected clusters were eligible to participate. In each census enumeration unit selected, 50 residents aged 50 years and older were chosen to participate in the study using compact segment sampling. The study participants underwent visual acuity (VA) measurement and lens examination; those with presenting VA (PVA) < 20/60 also underwent direct ophthalmoscopy. Moderate visual impairment (MVI) was defined as PVA < 20/60-20/200, severe visual impairment (SVI) was defined as PVA < 20/200-20/400, and blindness was defined as PVA < 20/400, all based on vision in the better eye with available correction. RESULTS: Out of 3 956 eligible individuals, 3 729 (94.3%) were examined. The age- and sex-adjusted prevalence of blindness was 0.9% (95% confidence interval (CI): 0.5-1.3). Cataract (48.6%) and glaucoma (14.3%) were the main causes of blindness. Prevalence of SVI and MVI was 0.9% (95% CI: 0.5-1.3) and 7.9% (95% CI: 6.0-9.7) respectively. Cataract was the main cause of SVI (65.7%), followed by uncorrected refractive error (14.3%), which was the main cause of MVI (55.2%). Cataract surgical coverage was 76.8% (calculated by eye) and 91.3% (calculated by individual). Of all eyes operated for cataract, 70.0% could see ≥ 20/60 and 15.3% could not see 20/200 post-surgery. CONCLUSIONS: Prevalence of blindness in Uruguay is low compared to other Latin American countries, but further reduction is feasible. Due to Uruguay's high cataract surgical coverage and growing proportion of people ≥ 50 years old, the impact of posterior pole diseases as a contributing factor to blindness might increase in future.

OBJETIVO: Investigar y describir la prevalencia y las causas de la ceguera y de la discapacidad visual moderada y grave en los adultos mayores residentes en Uruguay. MÉTODOS: Todas las personas de 50 años o más que vivían en los agrupamientos seleccionados aleatoriamente reunían los requisitos para participar. En cada unidad de enumeración censal seleccionada, se escogieron 50 residentes de = 50 años de edad para participar en el estudio mediante el empleo de un muestreo por segmentos compactos. Los participantes fueron sometidos a una medición de la agudeza visual (AV) y a un examen del cristalino; los que mostraban una AV de presentación (AVP) < 20/60 también fueron sometidos a oftalmoscopia directa. La discapacidad visual moderada (DVM) se definió como una AVP < 20/60–20/200, la discapacidad visual grave (DVG) como una AVP < 20/200–20/400, y la ceguera como una AVP< 20/400, todas ellas basadas en la visión del ojo que obtuvo un mejor resultado con la corrección disponible. RESULTADOS: De las 3 956 personas que reunieron los requisitos, se examinaron 3 729 (94,3%). La prevalencia ajustada por edad y sexo de la ceguera fue de 0,9% (intervalo de confianza (IC) de 95%: 0,5–1,3). La catarata (48,6%) y el glaucoma (14,3%) fueron las principales causas de ceguera. La prevalencia de la DVG y la DVM fue de 0,9% (IC de 95%: 0,5–1,3) y 7,9% (IC de 95%: 6,0–9,7), respectivamente. La catarata fue la causa principal de DVG (65,7%), seguida del error de refracción no corregido (14,3%), que fue la principal causa de DVM (55,2%). La cobertura quirúrgica de la catarata fue de 76,8% (calculada por ojo) y de 91,3% (calculada por persona). De todos los ojos operados de catarata, 70,0% presentaba una agudeza visual de = 20/60 y 15,3% tenía una agudeza visual < 20/200 después de la intervención quirúrgica. CONCLUSIONES: En Uruguay, la prevalencia de la ceguera es baja en comparación con otros países latinoamericanos, pero es factible lograr una reducción adicional. Como consecuencia de la alta cobertura quirúrgica de la catarata y la creciente proporción de personas de = 50 años en Uruguay, la repercusión de las enfermedades de la cámara ocular posterior como factor contribuyente a la ceguera podría aumentar en el futuro.

Traumas oculares no serviço de urgência da Fundação Banco de Olhos de Goiás / Ocular trauma in the emergency department of Goiás Eye Bank Foundation

OBJETIVO: Estudar e analisar os tipos de trauma ocular no serviço de urgência da Fundação Banco de Olhos de Goiás e orientar médicos generalistas quanto ao seu primeiro atendimento. MÉTODOS: Foram analisados 351 atendimentos no período de dezembro de 2010 a fevereiro de 2011, sendo que apenas nos casos de trauma ocular foram avaliados o sexo, idade, procedência, tipo de trauma e o tratamento realizado. RESULTADOS: Foi realizada uma análise de 351 atendimentos de urgência deste serviço, onde foi encontrado um total de 153 traumas oculares (43,6%), com predominância em 131 casos (85,6%) do sexo masculino. A faixa etária mais acometida foi a de adultos jovens de 20 a 39 anos, em 90 casos (58,8%). Goiânia foi a procedência mais frequente em 89 casos (58,2%). O trauma mecânico fechado por corpo estranho superficial foi o tipo de trauma mais comum com 95 casos (66,4%). O tratamento clínico foi amplamente mais predominante em 149 casos (97%). CONCLUSÃO: Em relação aos traumas oftalmológicos predominaram os pacientes com corpos estranhos superficiais do sexo masculino, na faixa etária economicamente ativa procedente de Goiânia, com tratamento clínico, e direta relação com acidentes ocupacionais, merecendo atenção especial quanto à prevenção.

PURPOSE: To study and analyze the types of ocular trauma in the emergency department of Goiás Eye Bank Foundation, Goiânia – Brazil and guide general physicians about the first medical contact. METHODS: An analysis was done in 351 visits between december, 2010 and february, 2011. The ocular trauma cases were evaluated by gender, age, origin, trauma type and treatment performed. RESULTS: Three hundred fifty-one emergency medical visits were analyzed and were found 153 ocular traumas (43.6%), showing predominance of 131 cases (85.6%) of men. The most frequent age was 20 to 39 year-old young male in 90 cases (58.8%). Goiânia was the most frequent origin with 89 (58.2%). The superficial foreign body mechanical trauma was the most common trauma type with 95 cases (66.4%). Clinical treatment was performed in 149 cases (97%). CONCLUSION: Concerning the ocular trauma, superficial foreign bodies predominated in males in working age coming from Goiânia treated clinically. There is a strong relationship with occupational accidents requiring special attention to prevention.

Idiopathic dilated episcleral vessels (Radius-Maumenee syndrome): case report / Dilatação idiopática dos vasos episclerais (síndrome de Radius-Maumenee): relato de caso

Radius-Maumenee syndrome comprises idiopathic dilated episcleral vessels that are usually associated with glaucoma. The case described herein is of a male patient, 69 years old, with chronic dilation of the episcleral vessels and glaucoma in his left eye, with no history of systemic disease. Visual acuity and fundoscopy were normal in both eyes. Tonometry measured 14 mmHg in the right eye and 25 mmHg in the left. Computed tomography angiography (CTA) was negative for carotid-cavernous fistula. The intraocular pressure of the left eye decreased to 20 mmHg with clinical treatment without regression of episcleral venous dilation. Trabeculectomy normalized the intraocular pressure and reduced the vessels. There was choroidal effusion on day 16 of the postoperative period, which resolved with corticosteroids. Although choroidal effusion can occur, the efficacy of trabeculectomy in controlling glaucoma and the reduction of episcleral vessels are clearly demonstrated.

A síndrome de Radius-Maumenee consiste na dilatação idiopática dos vasos episclerais geralmente associada ao glaucoma. Descreve-se o caso de paciente masculino, 69 anos, portador de dilatação crônica dos vasos episclerais e glaucoma do olho esquerdo, sem histórico de doença sistêmica. A acuidade visual e fundoscopia apresentaram-se normais em ambos os olhos. A tonometria mediu 14 mmHg no olho direito e 25 mmHg no esquerdo. A angiotomografia foi negativa para fístula carotídeo-cavernosa. A pressão intraocular do olho esquerdo diminuiu para 20 mmHg com tratamento clínico, sem regressão da dilatação venosa episcleral. A trabeculectomia normalizou a pressão intraocular e reduziu os vasos. Houve efusão coroidiana no 16º dia de pós-operatório que regrediu com corticoterapia. Embora possa ocorrer efusão coroidiana, destaca-se a eficácia da trabeculectomia no controle do glaucoma e na redução dos vasos episclerais.

Analyses of cataract surgery performed by the Unified Health System in Brazil, 2006-2007 / Análisis de las intervenciones quirúrgicas de cataratas efectuadas en el Sistema Único de Salud del Brasil en el 2006 y el 2007

OBJECTIVE: Estimate cataract surgical rates (CSR) for Brazil and each federal unit in 2006 and 2007 based on the number of surgeries performed by the Unified Health System to help plan a comprehensive ophthalmology network in order to eliminate cataract blindness in compliance with the target set by the World Health Organization (WHO) of 3 000 cataract surgeries per million inhabitants per year. METHODS: This descriptive study calculates CSR by using the number of cataract surgeries carried out by the Brazilian Unified Health System for each federal unit and estimates the need for cataract surgery in Brazil for 2006-2007, with official population data provided by the Brazilian Institute of Geography and Statistics. The number of cataract surgeries was compared with the WHO target. RESULTS: To reach the WHO goal for eliminating age-related cataract blindness in Brazil, 560312 cataract surgeries in 2006 and 568 006 surgeries in 2007 needed to be done. In 2006, 179121 cataract surgeries were done by the Unified Health System, corresponding to a CSR of 959 per million population; in 2007, 223317 were performed, with a CSR of 1179. With the Brazilian Council of Ophthalmology estimation of 165 000 surgeries each year by the non-public services, the CSR for Brazil would be 1842 for 2006 and 2051 for 2007. The proportions needed to achieve the proposed target were 38.6 percent in 2006 and 31.6 percent in 2007. CONCLUSIONS: Human resources, technical expertise, and equipment are crucial to reach the WHO goal. Brazil has enough ophthalmologists but needs improved planning and infrastructure in order to eliminate the problem, aspects that require greater financial investment and stronger political commitment.

OBJETIVO: Calcular las tasas de cirugía de cataratas (TCC) correspondientes al 2006 y el 2007 en todo el Brasil y en cada estado según la cantidad de intervenciones efectuadas en el Sistema Único de Salud, con el objeto de planificar una red integral de atención oftalmológica tendiente a eliminar la ceguera por cataratas, en cumplimiento de la meta fijada por la Organización Mundial de la Salud (OMS), de 3 000 intervenciones quirúrgicas de cataratas por millón de habitantes por año. MÉTODOS: En este estudio descriptivo se calculó la TCC según la cantidad de intervenciones quirúrgicas de cataratas llevadas a cabo en el Sistema Único de Salud del Brasil en cada estado, y se calculó la necesidad de intervenciones quirúrgicas de cataratas en el Brasil en el 2006 y el 2007 según los datos oficiales de la población proporcionados por el Instituto Brasileño de Geografía y Estadística. Se comparó la cantidad de intervenciones quirúrgicas de cataratas con la meta de la OMS. RESULTADOS: Para alcanzar la meta de la OMS de eliminar la ceguera producida por cataratas seniles en el Brasil, deberían haberse efectuado 560 312 intervenciones quirúrgicas de cataratas en el 2006, y 568006 en el 2007. En el 2006, se efectuaron 179 121 intervenciones quirúrgicas de cataratas en el Sistema Único de Salud, lo que representa una TCC de 959 por millón de habitantes; en el 2007, se realizaron 223317, con una TCC de 1179. Si estos datos se consideran junto con la estimación del Consejo Brasileño de Oftalmología de 165000 intervenciones quirúrgicas efectuadas cada año en los servicios no públicos, la TCC correspondiente al Brasil sería de 1842 para el 2006 y de 2 051 para el 2007. Las proporciones faltantes para lograr la meta propuesta fueron de 38,6 por ciento en el 2006 y de 31,6 por ciento en el 2007. CONCLUSIONES: Los recursos humanos, los conocimientos técnicos especializados y el equipo son esenciales para alcanzar la meta de la OMS. Brasil tiene suficientes oftalmólogos pero, para eliminar el problema, necesita una mejor planificación y más infraestructura, aspectos que requieren una mayor inversión financiera y un compromiso político más firme.

Preliminary clinical outcomes from the Peruvian National Cataract Elimination Plan / Resultados clínicos preliminares del Plan Nacional de Lucha contra la Ceguera por Catarata del Perú

OBJECTIVE: To evaluate the clinical outcomes of a publicly funded cataract elimination program. METHODS: Outcomes of all patients (186) who received extracapsular cataract extraction (ECCE) surgery free of charge at the Instituto Regional de Oftalmología in northern Peru in the first year (August 2008 to July 2009) of the Peruvian National Cataract Elimination Plan were compared retrospectively with the outcomes of all patients (68) who paid in the highest charge tier for ECCE surgery during the same period. Preoperatively, the median uncorrected visual acuity (UCVA) of National Plan patients was Hand Motion; the UCVA of paying patients was Counting Fingers (P = 0.09). Complication frequency and visual acuity (uncorrected visual acuity, pinhole visual acuity, and best correct visual acuity) were the primary outcome measures. The World Health Organization (WHO) Vision 2020 goal is for 85 percent of operated eyes to achieve 20/60 vision; the Ministerio de Salud del Perú goal is for 75 percent of eyes to achieve 20/50. RESULTS: One month postoperatively, only 24 percent of National Plan patients achieved a UCVA of 20/60. The median UCVA for both groups was 20/100 (P = 0.23). Intraoperative complications occurred in 27 percent of all patients; postoperative complications occurred in 39 percent. Patients more likely to have a poor outcome (UCVA < 20/200) were those who experienced a postoperative complication (odds ratio [OR] 3.3, P = 0.002), who experienced an intraoperative complication (OR 2.5, P = 0.01), and who were 75 years or older (OR 2.7, P = 0.008). National Plan patients were more likely to have an OCTET Grade II intraoperative complication (OR 4.2, P = 0.03) and were less likely to receive refractive services (OR 1.5, P = 0.002). CONCLUSIONS: Neither WHO nor Peruvian benchmarks for surgical outcome were achieved in the first year of the Peruvian National Cataract Elimination Plan. Providing more comprehensive services to patients and addressing variables correlated with poor outcomes may improve interventions and help achieve Vision 2020 goals.

OBJETIVO: Evaluar los resultados clínicos de un programa de lucha contra la ceguera por catarata con financiamiento público. MÉTODOS: Los resultados obtenidos de todos los pacientes (186) sometidos a una operación gratuita de extracción extracapsular de catarata (EECC) en el Instituto Regional de Oftalmología del norte del Perú, durante el primer año (de agosto del 2008 a julio del 2009) de la ejecución del Plan Nacional de Lucha contra la Ceguera por Catarata del Perú, se compararon retrospectivamente con los resultados de los pacientes (68) que pagaron los honorarios más elevados por una operación quirúrgica de EECC durante el mismo período. Antes de la intervención, la mediana de la agudeza visual sin corrección (AVSC) de los pacientes beneficiarios del plan nacional era de percepción de los movimientos de la mano; mientras que en los pacientes de pago era de conteo de dedos (P = 0,09). Como mediciones primarias de los resultados se consideraron la frecuencia de complicaciones y la agudeza visual (agudeza visual sin corrección, agudeza visual con agujero estenopéico y mejor agudeza visual correcta). La meta de la iniciativa Visión 2020 de la Organización Mundial de la Salud (OMS) es lograr que 85 por ciento de los ojos operados alcancen un nivel de visión mínimo de 20/60; la meta del Ministerio de Salud del Perú es que 75 por ciento alcancen un nivel de 20/50. RESULTADOS: Un mes después de la intervención, solo 24 por ciento de los pacientes beneficiarios del plan nacional alcanzaron una AVSC de 20/60. La AVCS mediana en ambos grupos fue de 20/100 (P = 0,23). En 27 por ciento de los pacientes aparecieron complicaciones intraoperatorias; y en 39 por ciento, complicaciones posoperatorias. Los pacientes con mayor probabilidad de obtener un resultado deficiente (AVSC < 20/200) fueron los que presentaron alguna complicación posoperatoria (razón de posibilidades [OR] 3,3,P = 0,002), los que padecieron una complicación intraoperatoria (OR 2,5, P = 0,01) y los de 75 años de edad o mayores (OR 2,7, P = 0,008). Los pacientes beneficiarios del Plan Nacional tuvieron mayores probabilidades de tener complicaciones intraoperatorias de grado II de la escala de OCTET (OR 4,2, P = 0,03) y menores probabilidades de recibir servicios de corrección refractiva (OR 1,5, P = 0,002). CONCLUSIONES: Durante el primer año de ejecución del Plan Nacional de Lucha contra la Ceguera por Catarata del Perú no se alcanzaron los puntos de referencia peruanos ni los de la OMS en cuanto a los resultados de la cirugía. La prestación de servicios más integrales a los pacientes y la atención de las variables correlacionadas con los resultados deficientes pueden mejorar las intervenciones y contribuir a que se alcancen las metas de la iniciativa Visión 2020.

Carência de atenção à saúde ocular no setor público: um estudo de base populacional / Shortage of ocular health care in the public system: a population-based study

Este estudo transversal de base populacional investigou a prevalência de utilização de serviços de saúde ocular e sua associação com fatores sócio-demográficos, necessidades em saúde e forma de financiamento da consulta. Avaliaram-se 2.960 indivíduos de 20 anos ou mais. Nos últimos cinco anos, 46 por cento dos entrevistados e 30 por cento daqueles com 50 anos ou mais não consultaram para os olhos. Dos que consultaram, 18 por cento foram em óticas, e apenas 17 por cento foram no setor público. O principal motivo foi não enxergar bem (69,5 por cento). Falta de dinheiro (29 por cento) e de tempo (24,6 por cento) foram os principais motivos para ter deixado de consultar. Idade, escolaridade e nível econômico estiveram diretamente associados com ter consultado nos últimos cinco anos. Ser mulher, ter catarata, glaucoma e usar correção, bem como consultar no setor privado também estiveram positivamente associados com o desfecho. É preciso não só aumentar a participação do setor público, integrando a saúde ocular a todos os níveis de atenção, ampliando a participação de outros profissionais de saúde, como também intensificar o rastreamento de problemas oculares e a sua prevenção.

This cross-sectional population-based study investigated the prevalence of eye care services utilization and the association with socioeconomic and demographic factors, need for health care, and type of service payment. The study evaluated 2,960 adults aged 20 and older. In the previous 5 years, 46 percent of the sample and 30 percent of those aged 50 and older had not visited an eye care service. Among the persons who used a service, 18 percent went to an optical store and only 17 percent used the public health system. The main reason for using eye care services was poor vision (69.5 percent). Lack of money (29 percent) and time (24.6 percent) were the most frequently cited reasons for non-utilization. Age, education, and economic status were directly associated with the outcome. Female gender, cataract, glaucoma, prescription eyewear, and private appointments were also associated with the outcome. It is necessary to increase the public health system's role, integrating ocular health with all levels of health care, expanding participation by other health professionals, and intensifying screening and prevention of eye problems.

Avaliação dos serviços de assistência ocular em população urbana de baixa renda da cidade de São Paulo - Brasil / Eye care services evaluation in a low-income urban population of São Paulo City - Brazil

OBJETIVO: Avaliar os serviços de assistência ocular do ponto de vista do usuário em população de baixa renda, na zona leste da cidade de São Paulo - Brasil. MÉTODOS: Estudo realizado por meio de inquérito domiciliar em uma amostra por conglomerados em três distritos de baixa renda da cidade de São Paulo - Brasil. No período de julho/2004 a janeiro/2005 foram realizadas 1.055 entrevistas com um representante do domicílio, sendo aplicado o questionário de responsividade aos serviços de assistência ocular em entrevista individual. RESULTADOS: Dos participantes, 71,56 por cento eram mulheres. A idade dos respondentes variou de 18 a 92 anos (41,42 ± 15,67 anos). Quanto à escolaridade, 525 (49,77 por cento) tinham 4 anos ou menos; 489 (46,35 por cento) entre 5 e 11 anos; 40 (3,79 por cento) 11 ou mais anos de estudo. Quanto à necessidade de utilização dos serviços de assistência ocular: 712 (67,49 por cento) relataram que algum morador do seu domicílio necessitou e obteve assistência ocular e 135 (12,80 por cento) nunca precisaram de assistência ocular. A barreira mais frequentemente citada para obtenção dos serviços de assistência ocular pelos respondentes foi o custo da consulta (77,29 por cento) seguida de tentativa frustrada de obtenção da assistência ocular (42,21 por cento). A frequência de avaliações positivas para os critérios contidos no questionário foi de 63,37 por cento. Dos 36,63 por cento respondentes insatisfeitos, o tempo de espera na sala de recepção dos serviços de assistência ocular foi o fator mais frequentemente apontado. CONCLUSÃO: As principais barreiras para obter assistência ocular foram o custo da consulta e a falta de acesso aos serviços, 63,37 por cento dos indivíduos que necessitaram e obtiveram assistência ocular nos últimos 12 meses mostraram-se satisfeitos.

PURPOSE: To evaluate eye care services from the user's perspective in a low income population from the east zone of the city of São Paulo - Brazil. METHODS: A household survey was performed using cluster sampling in three low income districts of the city of São Paulo - Brazil. From July/2004 to January/2005, 1055 interviews with an adult household representative were carried and an eye care system responsiveness questionnaire was administered through individual interview. RESULTS: 71.56 percent of the participants were women. Respondents' age ranged from 18 to 92 years (41.42 ± 15.67 years). Regarding schooling, 525 (49.77 percent) had four years or less; 489 (46.35 percent) between five and eleven years, 40 (3.79 percent) had eleven or more years of study. Eye care services need was reported as 712 (67.49 percent) declaring themselves or someone else of the household needing and obtaining services and 135 (12.80 percent) had never needed eye care. The most frequently cited barriers to obtain the eye care service by respondents was cost (77.29 percent), followed by unsuccessful attempt to obtain eye care (42.21 percent). General satisfaction for the criteria contained in the questionnaire was 63.37 percent. In the 36.63 percent dissatisfied respondents, the most frequently cited claim was the amount of time waited before consultation. CONCLUSION: The main barriers to obtain eye care services were cost of medical appointment and lack of access to the services. 63.37 percent of the individuals in need who had received eye care in last 12 months were satisfied with the service provided.
