大连市近年学龄前视力低常儿童屈光状态分布和弱视发生状况及其影响因素分析
The distribution of refractive status and the prevalence of amblyopia among preschool children with low vision in Dalian in recent years and their influencing factors
摘要
Abstract
Objective To investigate the distribution of refractive status and the occurrence of amblyopia in preschool children with low vision in recent years in Dalian City,as well as the influencing factors.Methods A total of 460 preschool children with low vision(920 eyes)who sought medical care at Dalian Maternal and Child Health Care Center from January 2020 to December 2022 were selected.The distribution of refractive status and the occurrence of amblyopia were analyzed.Factors influencing the occurrence of amblyopia were also analyzed.Results Among the 460 children,267 had amblyopia(434 amblyopic eyes,100 eyes with normal corrected visual acuity),and 193 children had normal corrected visual acuity(386 eyes).The proportion of myopia and hyperopia in eyes with normal corrected visual acuity was higher than that in amblyopic eyes(P＜0.05).The proportion of astigmatism in amblyopic eyes was higher than that in eyes with normal corrected visual acuity(P＜0.05).There was no statistically significant difference in the type of astigmatism between eyes with amblyopia and eyes with normal corrected visual acuity(P＞0.05).The dominant types of astigmatism in both groups were compound hyperopic astigmatism,accounting for 65.85％and 60.81％,respectively.There were significant differences in age,birth asphyxia,daily sleep time,daily outdoor activity time,picky eating,daily screen time(phone,computer,etc.),and reading and writing posture between children with amblyopia and those with normal corrected visual acuity(P＜0.05).The results of the multiple-factor Logistic regression analysis showed that daily sleep time and birth asphyxia were influencing factors for the occurrence of amblyopia(P＜0.05).Conclusion The distribution of refractive status in preschool children with low vision is mainly astigmatism,and the proportion of amblyopia is relatively high.The occurrence of amblyopia is influenced by factors such as daily sleep time and birth asphyxia.关键词
