Abstract:
611 children (297 boys and 314 girls) of a primary school were determined under 2% cyclogyl. (1) Among 611 children, refractive error was 70.46 % and emmetropia. 29.54 %. (2) As to the distribution of refractive errors, 72.47 % were hyperopic and 27.53 % myopic Hyperopia was more common than myopia. (3) Hyperopic refractive error was increased until 7 years of age. Since then it has been decreased 8.74 % yearly. Myopic refractive error has been increased 8.14 % yearly since 8 years of age. (4) The refractive errors were more frequent in women (37.81) than men (32.65 %) (5) Refractive errors were numerous around the age of 11. (24.77 %). (6) The degree of refractive errors varied, but in the great majority was less than 3 diopters. (7) As to the type of astigmatism; 59.42 % were with the rule and 39.94 % were against the rule.
