OBJECTIVE: The purpose of this study was to investigate the visual disorders and their causes in preschool children.
MATERIALS AND METHODS: We have examined 839 children of 2-6 years. They were divided into two age groups: of 2-3 years (I gr.) and of 4-6 years old (II gr.). We estimated the visual acuity at 3m distance, binocular vision, refractive status by cycloplegic skiascopy (sol. cyclogyli 1% x 2).
RESULTS: Impaired vision was found in 14.94% of children, but it was significant in the second group (p<0.05); binocular vision was absent in 4.2% of the children. The evaluation of refraction showed that the cause of visual disorders was hyperopia of various degree (43.26%), hyperopic astigmatism (23.08%), spasm of accommodation (14.42%). The second group had significantly more cases of astigmatism and spasm of accommodation (27.38% and 16.67%, respectively), less common--strabismus (1.19%); it was significantly different from the first group (p<0.05).
CONCLUSIONS: Visual disorders were diagnosed in 14.94% of 2-6 years children. Impaired vision of preschool children was caused by the ocular ametropias (hyperopia of various degrees, astigmatism) and disorders of accommodation.
