Progression in the Number of Cataract Surgeries in Brazil: 10 Years of Evolution.

OBJECTIVE: This study aimed to assess the frequency of cataract surgery in Brazil between 2010 and 2019 and determine the impact of public policies on preventing blindness, thereby providing evidence to conduct healthcare programs. METHODS: An analytical epidemiological approach was employed, which used data from public databases, specifically the Hospital Information System (SIH-SUS) and the Outpatient Information System (SIA-SUS). We focused on cataract surgeries conducted via phacoemulsification and extracapsular cataract extraction techniques between 2010 and 2019, mainly targeting senile cataracts within the Brazilian public health system. Data were analyzed on an annual basis and stratified by region. Trends over time were assessed using generalized additive models. RESULTS: A statistically significant upward trend in cataract surgeries was observed both nationally and within the South region (p < 0.05). Nationally, there was a 40.22% increase in surgeries between 2010 and 2019. Furthermore, the surgery rate per 1000 individuals aged ≥50 years varied across regions: nationally, it was 10.85, with rates of 9.23 in the Southeast, 13.86 in the Northeast, 9.23 in the South, 11.94 in the Midwest, and 14.2 in the North. CONCLUSION: All regions of the country, a satisfactory number of cataract surgeries were performed at some point. Only the Southern region demonstrated a notable upward trend in the number of cataract surgeries. Conversely, the remaining regions failed to sustain surgical performance, hindering consistent improvement in cataract-related conditions. To accurately gauge the prevalence of blindness in Brazil, it is crucial to examine the population growth among individuals aged ≥50 years.

Influence of lighting on visual performance.

PURPOSE: This review emphasizes the effect of light on visual efficiency, the impact of different lighting focuses, types of lighting, and their influence on vision and productivity. Light sources and standards are intriguing subjects for ophthalmologists. Guidelines regarding the level of lighting influence on visual activities can enhance visual performance.Methods: This article was developed based on literature reviews, with a bibliographic survey conducted in databases such as PubMed, MEDLINE, Web of Science, Embase, LILACS, and SciELO. RESULTS: Provides recommendations for understanding information regarding the influence of lighting on visual performance. CONCLUSION: Proper workplace lighting is crucial for improving visual efficiency, safety, productivity, and worker health. Efficient workplace lighting should avoid light sources directed towards the worker's face, prevent harmful glare, be more intense in the work area, and uniform in the rest of the room. Ophthalmologists should be knowledgeable about and provide guidance on correct lighting to ensure patient comfort and satisfaction with visual correction.

Impact of the COVID-19 pandemic on cataract surgeries in Brazil: A retrospective study.

PURPOSE: This study aimed to describe the behavioral patterns of data on cataract surgery performed in the Brazilian public health system before, during, and after the COVID-19 outbreak and estimate the setbacks generated by the pandemic to guide public policies. MATERIALS AND METHODS: This was an observational, longitudinal, and descriptive epidemiological study based on data retrieved from the public health system's databases of cataract surgeries performed each year and in each region from 2015 to 2022. RESULT: In Brazil, compared with the average of the 5-years preceding the pandemic, a 23 % reduction in the number of cataract surgeries was observed in 2020, followed by a 21 % increase in 2021, compensating for the majority of patients that were not operated on. However, the worsening situation of blindness caused by cataracts due to the pandemic not be avoided in the Central-West region, where unrecovered cases continue to accumulate. CONCLUSION: The COVID-19 pandemic did not worsen the situation of cataract blindness in Brazil due to the efficacy of the measures taken by the government in resuming elective surgeries. However, the auhtors recommend that the distribution of resources for cataract surgeries should consider regional discrepancies based on epidemiological data.

Teleconsultation at a public ophthalmic teaching hospital during the COVID-19 pandemic / Teleconsulta em um hospital público de ensino oftalmológico durante a pandemia do COVID-19

ABSTRACT Purpose: To analyze teleconsultation at a public ophthalmic teaching hospital during the COVID-19 pandemic in Brazil. Methods: Medical records of patients who requested ophthalmological teleconsultation between June 2020 and March 2021 were reviewed. The main outcomes included demographic data, eye disease symptoms, hypothesized diagnosis, and management. Moreover, the results of a satisfaction survey administered after the consultation were analyzed. Results: Medical records of a total of 161 patients were reviewed. The mean age was 45.98 ± 17.57 (8-90) years, and most were women (113, 70.20%). Only 57 (35.60%) of the patients had made previous follow-up visits to the hospital. The most frequent reason for consultation was the need for a new eyeglass prescription (73, 45.34%), followed by dry eye symptoms (16, 9.93%) and pterygium (13, 8.07%). Other reasons were the monitoring of previously diagnosed eye diseases, such as glaucoma, retinopathies, strabismus, and keratoconus. Regarding the satisfaction survey, 151 (93.78%) patients answered the online questionnaire. Most reported that they were satisfied with the teleconsultation (94.03%) and would participate in a future teleconsultation (90.06%). Conclusion: Teleconsultation could be widely used to assist patients in public ophthalmology healthcare and teaching hospitals. Even though new eyeglass prescriptions are a frequent reason for ophthalmological appointments, patients tend to be satisfied with teleconsultation, as it also provides guidance.

RESUMO Objetivo: Analisar a teleconsulta em um hospital público de ensino oftalmológico, durante o período da pandemia do COVID-19. Métodos: Foram revisados os registros médicos dos pacientes que solicitaram teleconsulta oftalmológica, no período de Junho de 2020 a Março de 2021. Os resultados incluem dados demográficos, sintomas de queixas oculares e hipóteses diagnósticas. Além disso, foram analisados dados da pesquisa de satisfação aplicada após cada teleconsulta. Resultados: Um total de 161 prontuários foram revisados. A idade média dos pacientes foi de 45.98 ± 17.57 (8 a 90) anos, a maioria mulheres, 113 (70,20%). Apenas 57 (35,60%) eram pacientes acompanhados no hospital previamente. A principal razão pela busca pela teleconsulta foi o erro refracional, 73 (45.43%), seguido de olho seco, 16 (9.93%), pterígio, 13 (8.07%). Outros motivos foram o acompanhamento de doenças prévias como glaucoma, retinopatias, miopia, estrabismo e ceratocone. Quanto a pesquisa de satisfação, 151(93,87%) pacientes responderam a pesquisa on-line. A maioria deles mostrou-se satisfeito com a teleconsulta (94.03%) e fariam uma nova teleconsulta (90.06%). Conclusão: A teleconsulta pode auxiliar a saúde pública em oftalmologia podendo ser utilizada em hospitais universitários. Embora o erro refracional tenha sido o motivo mais frequente nas consultas, os pacientes mostraram-se satisfeitos com essa modalidade de atendimento que serve como um serviço de orientação.

Analysis of a mobile learning app for ophthalmology in Brazil

ABSTRACT Purpose: To determine and analyze the usability metrics of a free mobile learning app for ophthalmology in Brazil. Methods: Metric data from the management dashboard of the CBOQUIZ app were used. All users registered on the platform between March 2019 and June 30, 2021 were included. The number of questions answered, number of correct answers, number of questions answered and correct answers by subject area, and user performance by geographic region were analyzed. Results: There were 458 active users during the research period and 107,245 questions answered (average, 234.16 questions per user). Of the questions answered, 81,600 (75.5%) were correct and 2,645 were incorrect. The states in Brazil with the best performance were Espírito Santo, Paraiba, and Paraná. The subject area with the lowest hit rate was basic sciences (69.1%), within which embryology demonstrated the lowest hit rate (58.28%). The posterior segment had the highest number of questions answered, followed by miscellaneous topics and the anterior segment. Questions on strabismus were the least answered. Conclusion: The app was used consistently throughout the period studied, and participants adhered to this teaching modality. Performance asymmetry was observed across the Brazil states. The CBOQUIZ app can be used to homogenize ophthalmology teaching in the country.

Situation of ophthalmology education in Brazil: supply versus demand / A situação da educação em Oftalmologia no Brasil: oferta versus demanda

ABSTRACT Purpose: The number of medical schools in Brazil has increased in recent years; however, vacancies for specialization in ophthalmology probably have not kept up with the growing demand. This study wants to estimate the increase in medical schools, the demand for ophthalmology specialization, and evaluate learning opportunities in ophthalmology. Methods: This was a retrospective study with research from the Ministry of Education and Brazilian Council of Ophthalmology database from 2002 to 2021. These data were checked through 120 notices published by the institutions in 2021. Results: The number of medical school vacancies increased by 370%, whereas the number of certified ophthalmology vacancies increased by 64%. There was an 11.4% misalignment between the Brazilian Council of Ophthalmology data in the Ministry of Education. Conclusion: The proportion of medical graduates has increased much more than opportunities for ophthalmology specialization. The effect on the search for unaccredited specialization positions is unknown, and policies for monitoring the specialization of ophthalmology vacancies should be established.

RESUMO Objetivo: Nos últimos 20 anos, o número de escolas médicas no Brasil aumentou, mas as vagas para especialização em Oftalmologia não acompanharam a demanda crescente. Este estudo quer estimar a demanda por especialização e avaliar a oferta de oportunidades de aprendizado em Oftalmologia. Métodos: Estudo epidemiológico com pesquisa em banco de dados provenientes do Ministério da Educação e Conselho Brasileiro de Oftalmologia. Estes dados foram checados através de 120 editais publicados pelos serviços de Residência em 2021. Resultados: De 2002 a 2021, o número de vagas em faculdades de Medicina aumentou 370%, enquanto o número de vagas certificadas de especialização em Oftalmologia aumentou 64%. Houve um desalinhamento de 11.4% entre os dados do Conselho Brasileiro de Oftalmologia e do Ministério da Educação. Conclusão: A proporção de graduados em Medicina aumentou muito mais do que a oferta de oportunidades de especialização em Oftalmologia, o impacto disto na busca por vagas de especialização não acreditadas é desconhecido, políticas de monitoramento das vagas de especialização em Oftalmologia devem ser estabelecidas.
