The politics of avoidable blindness in Latin America--surgery, solidarity, and solutions: the case of Misión Milagro.

Avoidable blindness, especially when caused by cataracts, is a disease primarily of the economically disadvantaged sectors of the population. With a focus on Latin America and the Caribbean, this paper focuses on the program Misión Milagro within its historical, political, and economic contexts. This initiative, led by the governments of Cuba and Venezuela, covers close to 35 countries across Latin America, the Caribbean, Asia, and Africa. It is well-known throughout Latin America as close to 2 million patients have undergone free screening, corrective surgery, and rehabilitation since its inception in 2004. Misión Milagro shows that implementation of a massive initiative to curb avoidable blindness caused by cataracts in a relatively short time is feasible. The program is also built upon a unique model of international cooperation, which stresses social objectives and solidarity rather than hegemonic international initiatives built on commercial relationships. It also provides elements that could be applied to other public health issues of global or national relevance, not only to other low-middle-income countries, but also to high-income countries such as Canada.

Validity of recall absent schoolchildren to free eye health projects.

PURPOSE: To analyze the results of recall absent schoolchildren to eye health projects. METHODS: Cross-sectional study. Visual screening was performed in schoolchildren attending 1(st) to 4(th) grades at public schools, from 7 to 10 years-old, to select and forward to complete ophthalmic evaluation. The projects were performed during weekends, at a public school, in the same municipality. Free transportation, food and eyeglasses were offered. A second opportunity of examination was offered to the students who were absent from the first call, with the same facilities. RESULTS: 51,509 schoolchildren had their vision tested, 14,651 (28.4%) were referred for ophthalmic examination. Of these, 8,683 (59.3%) attended the first call, 2,228 (37.3%) attended the recall and 25.5% of parents did not take their children to ophthalmic examination. The need for eyeglasses for children who attended the examination was 23.8% and 32.0% in the first opportunity and recall, respectively. The recall increased the coverage in 15.2% (59.3% to 74.5%). CONCLUSION: An expressive number of parents (25.5%) did not bring their children to be examined, even at a second opportunity of exam. The facilities offered: access, free examination, transportation and glasses. Children who were absent in the first opportunity and appeared at recall had a greater need for eyeglasses. Recall increased the coverage in 15.2% (59.3% to 74.5%) and it is not recommended when financial resources are limited.

OBJETIVO: Analisar os resultados da reconvocação de escolares faltosos a projeto de saúde ocular. MÉTODOS: Estudo transversal descritivo. Escolares de 7 a 10 anos de 1ª a 4ª séries do ensino fundamental foram triados nas escolas e encaminhados para exame oftalmológico completo. Os exames foram realizados durante fins de semana, em escola pública. Foram oferecidos transporte, alimentação e óculos gratuitos. Uma segunda oportunidade de exame foi oferecida aos faltosos, com as mesmas facilidades. RESULTADOS: Foram triados 51.509 escolares e encaminhados 14.651 (28,4%). Compareceram 8.683 crianças (59,3%) na primeira convocação. Os escolares faltosos (5.968) foram reconvocados e 2.228 (37,3%) compareceram à reconvocação, sendo que 25,5% dos pais não levaram seus filhos para exame. A necessidade de óculos, para crianças que compareceram ao exame, foi de 23,8% e 32,0%, na primeira convocação e reconvocação, respectivamente. A reconvocação aumentou a cobertura do projeto em 15,2% (59,3% to 74,5%). CONCLUSÃO: Um número expressivo de pais (25,5%) não leva seus filhos para exame, apesar das facilidades oferecidas de acesso, transporte, exame e óculos gratuitos. A necessidade de óculos foi maior nos escolares que compareceram à reconvocação que na primeira convocação. A reconvocação aumentou a cobertura de 59,3 para 74,5% e não está indicada quando os recursos financeiros são limitados.

Why are there defaulters in eye health projects?

PURPOSE: To identify barriers to attendance for eye examination of schoolchildren. METHODS: Cross-sectional study. Students in grades 1-4 in elementary school in Guarulhos (Brazil) were screened and referred for ophthalmic examination in 2006. Facilities offered in this project were: examination arranged during weekends, free transportation, spectacle donation and two different opportunities for exam. A questionnaire was applied, by interview, to a sample consisted of students' parents attended in a community project who missed the first call and attended the recall, to identify the reasons for non-attendance. RESULTS: The sample consisted of 767 parents or guardians, corresponding to an equal number of schoolchildren. Personal characteristics of the students: 49.2% male and 50.8% female, 60.2% of them had never received previous ophthalmologic evaluation. Reported reasons for no-show to the project: parents had not received appropriate orientation (35.6%), loss of working day (20.6%), illness (12.4%), had another appointment (10.0%). The need for eyeglasses was higher in the recall. CONCLUSIONS: A significant number of parents did not take their children for ophthalmological exams, even when a second opportunity was offered in projects with transportation facilities, free exams performed during weekends and spectacle donation. The main causes of absenteeism were lack of awareness and work. For 87.1% of the absenteeism cases, the difficulties could be overcome via improved structuring of the first call. A recall increases attendance coverage of target population by only 15.2% (59.3 to 74.5%). Notably, the eye exam campaign was the first exam for most of the absent students.

Diabetic retinopathy screening among Hispanics in Lea County, New Mexico.

A project of diabetic retinopathy screening among Hispanics was implemented to increase awareness among the participants about diabetic retinopathy, screen for retinopathy, and make recommendations for further follow-up to enable them to save years of vision. Hispanics with diabetes are at a higher risk than non-Hispanics to develop retinopathy. A convenience group of 19 adults participated in the project. A pretest to determine participants' knowledge about diabetic retinopathy was administered. Subsequently, the participants were screened for diabetic retinopathy. On that occasion, a nurse instructed the individual participants about different aspects of diabetic retinopathy and provided them with brochures. After three weeks, posttests were administered to evaluate their awareness level and compliance with recommendations. Data were analyzed using a dependent groups' t-test. A significant increase (6.6 percent) in the awareness levels of the participants was found. It is recommended that voluntary collaborative efforts among various individuals and institutions should occur to organize similar community projects that may otherwise become prohibitive due to costs.

[Proposal for a procedure for the detection of ophthalmic disorders in school children]. / Proposição de procedimento de detecção sistemática de perturbações oftalmológicas em escolares.

The proposal for a visual acuity test (A.V.) arose from a survey conducted among School Children of the "Ciclo Básico (C.B.)" i.é., the first two years of Elementary School in S. Carlos, S. Paulo State, Brazil. Nine schools participated in this study. The teachers were properly trained to apply the A. V. and squinting tests according to a standardized procedure. Of 2,025 children tested, 88.1% showed levels of A. V. higher than 0.8, and a squinting prevalence of 2.17%. When the application of the test was over, each school presented its proposals for the systematical application of such tests. These proposals had a common point: the test should be applied by the teachers themselves under the supervision of the coordinators of the C. B. The school nurse would be responsible for giving overall assistance to all the activities of the program at all levels.
