[Prevalence of refractive anomalies among school children].

Complex ophthalmological examination of schoolchildren was carried out in 7 schools and 1 gymnasium. A total of 6027 children aged 6-17 years were examined (3188 boys and 2839 girls). Ocular disorders were detected in 1011 (16.8%), of these refraction abnormalities in 593 (58.7%) and accommodation spasm in 242 (23.9%). Myopic refraction was detected in 307 children (5.1%), medium hypermetropia in 150 (2.5%), high hypermetropia in 7 (0.1%), and astigmatism in 129 (2.1%). The main causes of visual disorders in schoolchildren are refraction abnormalities, primarily myopia.
