Abstract
- 518 children (282 boys and 236 girs) of a primary school were determined under mydrin-p instillation. (1) Among 518 children, Ammetropia was 43.6% emmetropia 56.4%. (2) As to the distribution of refractive error 38.2% were hyperopia and 4.1% myopic. (3) There was an anuual decrease in the incidence of hyperopia both in the country and city. In contrast, the incidence of myopia showed an annual increase in city only. (4) The majority of refractive error were less than 3 diopter. (5) "With the rule" astigmatism was more commonly found than "against the rule". (6) The incidence of myopia among primary school children in the country had dropped to 4.1 % as compared with 13.7% in city.
