Investigation of the refractive status of preschool children in Xiantao, Hubei Province

Abstract

AIM: To investigate the refractive status of the preschool children in Xiantao, Hubei Province in order to find out the abnormal refraction error beyond the physiological range. METHODS: In this cross-sectional study, we investigated preschool children in kindergartens and the scattered ones were 12 716(25 432 eyes)ranging from 6mo～6 years old. 1 581 children(3 162 eyes)were diagnosed ametropia by Suresight refractive screening instrument, which were confirmed again after mydriasis optometry. RESULTS: The incidence rate of ametropia in preschool children in Xiantao was 12.4%, and statistics showed no significant difference between boys and girls(P>0.05), but had differences of morbility rate among each age group(PCONCLUSION: The incidence rate of ametropia decreases with age increasing in the preschool children from 6mo～6 years old, which imply preschool children should have mydriasis optometry in order to find out amblyopia and other congenital eye disease.
