“…On the second trip in 1999, the first author of this manuscript examined all Yanomami communities (eight) along the Marauiá river on the left bank of the Rio Negro. 8 These communities are located approximately the same distance from the Equator, about 70 km ( Figure 1). During each visit, the examiners tried to assess the entire community.…”

Purpose To compare the prevalence of pterygium and cataract in four indigenous populations of the Brazilian Amazonian rain forest (Arawak, Tukano, Maku, and Yanomami) with different ethnic and social behaviour backgrounds. Methods A cross-sectional pterygium and cataract survey was performed in 624 adult Indians of the Brazilian rain forest belonging to four different ethnic groups. The Indians were classified according to their social behaviour in two groups: Arawak and Tukano (group 1) and Maku and Yanomami (group 2). Slit-lamp biomicroscopy was employed to examine the entire sample. All subjects were classified as 1 or 0 according to the presence or absence pterygium and cataract. Sex and age were also recorded. Gender was not associated with pterygium (P ¼ 0.1326) and cataract (P ¼ 0.2263) in both groups. Elderly subjects showed a significantly higher prevalence of cataract (Po0.0001). The prevalence of pterygia did not increase with age (P ¼ 0.8079) in both groups. Conclusion Indians of group 1 have higher prevalence of pterygia and cataract than Indians of group 2. Social behaviour, especially the rate of sun exposure, appears to be the main factor for the different rates of pterygium and cataract displayed by these indigenous people of the Brazilian rain forest.

“…4 However, various studies realized after the mid 1980s, in different regions and states, found prevalence varying between 1.5% and 47.7% for active trachoma and from 0.1% to 2.0% for trichiasis, including indigenous populations. 1,2,[5][6][7][8]11,12,14,15 The WHO considers trachoma to be a neglected disease. According to its criteria for eliminating the disease as a cause of blindness, the prevalence of trachomatous infl ammation -follicular needs to be reduced to under 5% in children aged from one to nine, and prevalence of trachomatous trichiasis to less than one case per thousand inhabitants in a community or district.…”

OBJECTIVE:To estimate the prevalence and describe the distribution of trachoma among schoolchildren in Brazilian municipalities. METHODS:Cross-sectional study, using cluster sampling, of the schoolchildren population of the Brazilian municipalities with Human Development IndexMunicipal lower than the national average. This trachoma prevalence survey was conducted by the Ministry of Health, in the period [2002][2003][2004][2005][2006][2007]. There were 119,531 schoolchildren selected from 2,270 schools located in 1,156 municipalities. The selected schoolchildren underwent an external ocular examination, with a magnifying glass (2.5X), to detect clinical signs of trachoma according to the WHO criteria. The prevalence of trachoma, by state and national level, and their respective 95% confi dence intervals were estimated. Chi-square and Chi-square for trends tests were used to compare categorical variables.RESULTS: There were 6,030 cases of trachoma detected, resulting in a prevalence of 5.0% (95%CI 4.5;5.4). There was no signifi cant difference between the sexes. The prevalence of trachoma was 8.2% among children under 5 years of age, decreasing among higher age groups (p < 0.01). There was a signifi cant difference in prevalence between urban and rural areas, 4.3% versus 6.2% respectively (p < 0.01). Cases were detected in 901 municipalities (77.7% of the sample), in all regions of the country. In 36.8% of the selected municipalities, the prevalence was higher than 5%. CONCLUSIONS:The study shows that trachoma is a signifi cant public health problem in Brazil, contradicting the belief that the disease had been controlled in the country. The survey provides a baseline for evaluating planned interventions aimed at achieving the goal of global certifi cation of elimination of trachoma as a cause of blindness in Brazil by 2020.

Prevalência de Tracoma em crianças em idade escolar no município de Turmalina, MG RESUMOO tracoma, tido equivocadamente como erradicado em nosso meio, encontra-se na lista de doenças negligenciadas. Trata-se da maior causa de cegueira evitável do mundo, sendo encontrado predominantemente nos países subdesenvolvidos. Diversos trabalhos têm demonstrado que esta doença atualmente se faz presente em todas as regiões do Brasil, o que evidencia que tanto o governo (nas esferas federal, estadual e municipal), quanto a academia devem continuar a considerar o tracoma entre as causas de cegueira em nosso meio. Neste trabalho, procurou-se levantar a prevalência de tracoma entre as crianças de sete a quinze anos matriculadas nas escolas da rede pública do município de Turmalina, MG. A pesquisa foi realizada neste município, situado no Vale do Jequitinhonha, considerando que existem nele regiões com populações em situação de alta vulnerabilidade social, portanto com características propícias para o surgimento da doença. Participaram da pesquisa seis médicos e onze enfermeiros com atuação na atenção primária, capacitados e padronizados para tal.
