Abnormalities in visual processing caused by visual deprivation or abnormal binocular interaction may induce amblyopia, which is characterized by reduced visual acuity. Occlusion therapy, the conventional treatment, requires special attention as occlusion of the fellow normal eye may reduce its visual acuity and impair binocular vision. Besides recovering visual acuity, some researchers have recommended restoration of stereoacuity and motor fusion and reverse suppression in order to prevent diplopia. Recent studies have documented that the amblyopic visual cortex has a normal complement of cells but reduced spatial resolution and a disordered topographical map. Changes occurring in the late sensitive period selectively impact the parvocellular pathway. Distinct morphophysiologic and psychophysical deficits may demand individualization of therapy, which might provide greater and longer-lasting residual plasticity in some children.

“…However, when considering the high cost of the device and the ease and low cost of using the Snellen charts, it becomes a viable alternative for the detection of visual disorders in children, being able to identify the visual acuity 6 . The present project makes use of the ease of dealing with visual acuity during childhood, and uses this approach in order to prevent future damage that could generate bigger problems.…”

Objetivo: Observar o nível de acuidade visual (AV) de estudantes do ensino fundamental público de Curitiba, bem como avaliar a relação entre redução visual, aprendizado e as condições estruturais de estudo. Métodos: Medida da AV dos alunos de primeira a terceira série de uma escola pública de Curitiba pelo método de Snellen, medição do comprimento e intensidade luminosa das salas, além do tamanho das letras no quadro negro e dos livros didáticos. Obtenção do boletim escolar dos alunos com baixa visão.Resultados: Das 242 crianças examinadas, 225 (92,97%) apresentaram acuidade visual boa, ou seja, AV 20/20 ou 20/25 em ambos os olhos, e 17 (7,03%) apresentaram AV igual ou pior que 20/30. Desses 17, somente um sentava na última linha de carteiras, o qual era o único que apresentava notas abaixo da média; todos os outros 16 tiveram notas na média escolar. A iluminação das salas de aulas estavam todas dentro do preconizado pelo NBR-5413. O tamanho da letra usada pela professora no quadro negro corresponde a 20/200 da tabela de Snellen, e no livro ao que corresponde J3 da tabela de Jaeger. Conclusão: A escola fornece condições e estrutura adequadas para o aproveitamento pleno dos alunos. Pode-se relacionar aprendizado com boas condições de trabalho escolar. Sendo assim, além de uma triagem da AV, as escolas devem estar atentas as condições estruturais necessárias para um bom trabalho escolar. Descritores: Acuidade visual; Crianças; Instituições acadêmicas;Aprendizagem;Avaliação educacional Purpose: Verify the rate of non-detectable low visual acuity (VA) in a public school of Curitiba and evaluate the relation between vision reduced, learning and study condition. Methods: Snellen visual acuity testing was done to all students from first to third grades at a Municipal School of Curitiba. Classroom's length and light intensity were obtained as well as the size of blackboard and books' letters. Academic scores were obtained from all students with VA equal or less than 20/30OU.Results: Of all 242 students, 225 presented VA equal or better than 20/25, and 17 (7.03%) equal or worse than 20/30. One of those 17 students study on the last row of chairs and had a low school performance. The light intensity was within the rules of NBR-5413. Besides that, the letter of blackboard corresponds to 20/200 in Snellen VA test, and the book's letters corresponds to J3 in Jaeger near VA test.Conclusion:The school presented good conditions and structure for schoolwork. However, learning and good condition of studying could be related. In addition to a screening of VA, schools must be mindful of the conditions necessary for good schoolwork.
