Assessment of eye health programme reach by comparison with rapid assessment of avoidable blindness (RAAB) survey data, Talagang, Pakistan.

BACKGROUND: The purpose of this study was to quantify how much of the burden of visual impairment (VI) and unmet need in Talagang, identified by Rapid Assessment of Avoidable Blindness (RAAB) survey data, has been addressed by Community Eye Health (CEH) programme efforts. METHODS: A RAAB survey was carried out in November 2018, with 2,824 participants in Talagang Tehsil, Punjab, Pakistan, aged 50 and over. Census data were used to extrapolate survey data to the population. Alongside this, a CEH programme was launched, consisting of community eye screening, and onward referral to rural health centres, secondary or tertiary ophthalmological services, as required. This health intervention aimed to address the eye care needs surfaced by the initial survey. From 2018 to 2022, 30,383 people aged 50 or over were screened; 14,054 needed referral to further steps of the treatment pathway and more detailed data collection. Programme data were compared to estimates of population unmet needs. Main outcome measures were prevalence of VI, and proportion of need met by CEH Programme, by cause and level of VI. RESULTS: Among those aged 50 and over, 51.0% had VI in at least one eye. The leading causes were cataract (46.2%) and uncorrected refractive error (URE) (25.0%). In its first four years, the programme reached an estimated 18.3% of the unmet need from cataract, and 21.1% of URE, equally in both men and women. CONCLUSIONS: Robustly collected survey and programme data can improve eye health planning, monitoring and evaluation, address inequities, and quantify the resources required for improving eye health. This study quantifies the time required to reach eye health needs at the community level.

Near vision data and near correction requirements from community eye health programmes in nine countries.

BACKGROUND: Recent estimates of global prevalence of uncorrected presbyopia range from 510 to 826 million. There is a shortage of primary data regarding Near Visual Impairment (NVI) magnitude. METHODS: Near visual acuity (NVA) and NVI data was collected from over 388,000 people aged 35 or over across 9 countries, within Community Eye Health programmes between January 2022 and June 2023. In Kenya (n = 34,328), dioptric power of required near correction was also recorded, and any association with age, gender or level of NVA was assessed via linear regression model. RESULTS: 146,801 of 388,939 people failed initial near vision screening (37.74%, 95% CI 37.59-37.89%), with significantly higher prevalence of NVI in Sub-Saharan Africa than South Asia. Of those with distance acuity 6/12 or better, 27.97% failed (95% CI 27.81-28.13%) with evidence of difference between genders (p < 0.001): 30.77% of women vs. 24.47% of men. The most commonly required dioptric powers of correction were +2.00D, +2.50D and +3.00D, and required power correlated with age and NVA. CONCLUSIONS: NVI remains common among Community Eye Health programme participants aged 35 and over. Data from large scale programmes such as these provide an opportunity to contribute to more accurate epidemiological estimates, and to guide future research, resource planning and intervention, ideally with improved standardisation of testing in the future.

Inequities in visual health and health services use in a rural region in Spain / Desigualdades en salud visual y uso de servicios de salud en una población rural en España

Objective: To analyse perceived visual health and health services use in a rural population in relation to socioeconomic characteristics and compared with the general population in Spain. Method: Cross-sectional study in a rural population using a structured questionnaire including questions comparable to the Spanish National Health Survey (2012). A descriptive analysis was carried out through the calculation of frequencies and prevalence, the χ2 test for independent variables, contrasts of proportions and logistic regression to obtain associations between the rural and general populations and socioeconomic variables. Results: For the rural population studied, the prevalence of poor perceptions of visual health is 40.8% in men and 39.4% in women, and is strongly associated with age, employment situation, income and presence of chronic diseases (p ??0.001). Compared with the general population, the rural population has a higher risk of presenting with serious difficulties related to farsightedness (OR: 2.56; 95% CI: 1.32-4.95) and make less use of optical correction (OR: 0.57; 95%CI: 0.44-0.74). The use of health services is not sufficient for adequate prevention, particularly in diabetics. For those affected by poor vision, the distance to travel to receive an eye exam, the belief that eyesight problems come with age and the cost of glasses are the principal reasons used to explain why eyesight problems are not resolved. Conclusions: The rural population presents worse visual health that is influenced by social and economic factors. Improving accessibility and reducing barriers is essential to tackle avoidable visual disability and reduce health inequities

Objetivo: Analizar la salud visual y el uso de servicios de salud en una población rural periférica en relación a variables socioeconómicas y a la población general española. Métodos: Estudio transversal en población rural con administración de cuestionario estructurado incluyendo preguntas comparables a la Encuesta Nacional de Salud en España (2012). Se realizó un análisis descriptivo a través del cálculo de frecuencias y prevalencias, el uso de la prueba χ2 para la independencia de variables y el contraste de proporciones y regresión logística para obtener asociaciones entre variables en población rural y general. Resultados: En la población rural estudiada, la prevalencia de mala salud visual percibida es del 40,8% en los hombres y del 39,4% en las mujeres, y está fuertemente asociada a la edad, la situación laboral, el nivel de ingresos y la presencia de enfermedades crónicas (p ??0,001). Presentan mayor riesgo de afrontar importantes dificultades en visión lejana (odds ratio [OR]: 2,56; intervalo de confianza del 95% [IC95%]: 1,32-4,95) y hacen un menor uso de corrección óptica (OR: 0,57; IC95%: 0.44-0.74) en comparación con la población general. El uso de los servicios de salud es insuficiente para una adecuada prevención, particularmente en las personas diabéticas. Aquellos/as con dificultades visuales señalaron la distancia al centro de salud, asociarlo a la edad y el precio de las gafas como principales barreras en el acceso a una solución. Conclusiones: La población rural presenta peores indicadores de salud visual, influenciados por factores socioeconómicos. Se requieren acciones que aborden la discapacidad visual por causas evitables y reducir las inequidades en salud

Vision and Hearing Health Inequities in the Roma population: A National Cross-Sectional Study in Spain.

We analyzed vision and hearing health status in the Spanish Roma population compared with the general population and its influence on mental health and social participation. We conducted a Cross-sectional study on Roma population (n = 1.167) compared to general population in Spain (n = 21.007). We analyzed the use of optical and hearing aids, vision and hearing limitations and associations with mental health, diagnosed depression and social participation; through prevalence, odds ratio adjusted by age (AOR), Chi square independence test and contrast of proportions (p < 0.05). The Roma population are more likely to present vision limitations-far sight AOR = 3.76 (3.13-4.55), near sight AOR = 3.18 (2.33-4.35)-, hearing difficulties-AOR = 1.41 (1.15-1.72)-, and lower use of corrective aids than the general population. These findings were associated with poor mental health and lower social participation (p < 0.01). Vision and hearing limitations affect unequally in Spain. Addressing avoidable vision and hearing impairment among Roma population is needed to reduce health inequities.

Visual health screening by schoolteachers in remote communities of Peru: implementation research.

OBJECTIVE: To describe the adaptation and scaling-up of an intervention to improve the visual health of children in the Apurimac region, Peru. METHODS: In a pilot screening programme in 2009-2010, 26 schoolteachers were trained to detect and refer visual acuity problems in schoolchildren in one district in Apurimac. To scale-up the intervention, lessons learnt from the pilot were used to design strategies for: (i) strengthening multisector partnerships; (ii) promoting the engagement and participation of teachers and (iii) increasing children's attendance at referral eye clinics. Implementation began in February 2015 in two out of eight provinces of Apurimac, including hard-to-reach communities. We made an observational study of the processes and outcomes of adapting and scaling-up the intervention. Qualitative and quantitative analyses were made of data collected from March 2015 to January 2016 from programme documents, routine reports and structured evaluation questionnaires completed by teachers. FINDINGS: Partnerships were expanded after sharing the results of the pilot phase. Training was completed by 355 teachers and directors in both provinces, belonging to 315 schools distributed in 24 districts. Teachers' appraisal of the training achieved high positive scores. Outreach eye clinics and subsidies for glasses were provided for poorer families. Data from six districts showed that attendance at the eye clinic increased from 66% (45/68 children referred) in the pilot phase to 92% (237/259) in the implementation phase. CONCLUSION: Adaptation to the local context allowed the scaling-up of an intervention to improve visual health in children and enhanced the equity of the programme.

Reducing visual deficits caused by refractive errors in school and preschool children: results of a pilot school program in the Andean region of Apurimac, Peru.

BACKGROUND: Refractive error is defined as the inability of the eye to bring parallel rays of light into focus on the retina, resulting in nearsightedness (myopia), farsightedness (Hyperopia) or astigmatism. Uncorrected refractive error in children is associated with increased morbidity and reduced educational opportunities. Vision screening (VS) is a method for identifying children with visual impairment or eye conditions likely to lead to visual impairment. OBJECTIVE: To analyze the utility of vision screening conducted by teachers and to contribute to a better estimation of the prevalence of childhood refractive errors in Apurimac, Peru. Design : A pilot vision screening program in preschool (Group I) and elementary school children (Group II) was conducted with the participation of 26 trained teachers. Children whose visual acuity was<6/9 [20/30] (Group I) and ≤ 6/9 (Group II) in one or both eyes, measured with the Snellen Tumbling E chart at 6 m, were referred for a comprehensive eye exam. Specificity and positive predictive value to detect refractive error were calculated against clinical examination. Program assessment with participants was conducted to evaluate outcomes and procedures. RESULTS: A total sample of 364 children aged 3-11 were screened; 45 children were examined at Centro Oftalmológico Monseñor Enrique Pelach (COMEP) Eye Hospital. Prevalence of refractive error was 6.2% (Group I) and 6.9% (Group II); specificity of teacher vision screening was 95.8% and 93.0%, while positive predictive value was 59.1% and 47.8% for each group, respectively. Aspects highlighted to improve the program included extending training, increasing parental involvement, and helping referred children to attend the hospital. CONCLUSION: Prevalence of refractive error in children is significant in the region. Vision screening performed by trained teachers is a valid intervention for early detection of refractive error, including screening of preschool children. Program sustainability and improvements in education and quality of life resulting from childhood vision screening require further research.
