Abstract

|
|
645 children (330 boys and 315 girls) of a primary school were determined under 2 Cyclogyl.
(1) Among 645 children, refractive error was 57.2% and emmetropia 42.8%.
(2) As to the distribution of refractive errors, 33.8% were hyperopic and 11.4 % myopic. Hyperopia was more common than myopia.
(3) Hyperopic refractive error was increased until 7 years of age. Since then it his been
decreased yearly. Myopic refractive error has been increased yearly since 8 years of age.
(4) The refractive errors were relatively equal rate in girls (28%) and boys (29%)
(5) Refractive errors were numerous around the age of 7 (24. 7 %).
(6) The degree of refractive errors varied, but in the great majority was less than 3 diopters.
(7) As to the type of astigmatism, 75% were with the rule and 23.7% were againat the rule.
(8) The myopic refractive errors were decreased in 1973 year (24.7%) than 1967 year (27.576).
