Abstract
- 556 children(220 boys and 336 girls) of clinical ametropia among 4715 children of a grade school were determined under 5% homatropine cycloplegia. 1) As to the distribution of refractive errors, 60.2% were myopic and 32,7% were hyperopic; 17.8% had astigmatism and 81.1% did not. 2) Refractive errors were numerous around the age of 11. 3) The degree of refraetive errors varied, but in the great majority was less than -3.00 D. 4) As to the type of astigmatism, 52.2% were with the rule and 41.2% were against the rule. 5) Only 12 children were anisometropic.
