摘　　要：目的:探讨新冠疫情前、中、后广州市白云区学龄前儿童散光变化特点,进一步为完善儿童视力防控提供参考。方法:回顾性分析2018-01/2021-12连续4a参加广州市白云区儿童视力筛查的4岁以下学龄前儿童2 273例4 546眼的视力数据。根据入组年龄分为1岁年龄组(年龄<1岁,420例)、2岁年龄组(1岁≤年龄<2岁,543例)、3岁年龄组(2岁≤年龄<3岁,614例)、4岁年龄组(3岁≤年龄<4岁,696例),分析纳入儿童双眼散光度数及散光患病情况。结果:2018年,1岁年龄组双眼散光度数均高于其他年龄组(P<0.05)。2020年,四组学龄前儿童双眼散光度数相比2019年均明显增加(P<0.05)。2021年,四组学龄前儿童双眼散光度数相比2020年均明显下降(P<0.05)。2019~2020年,四组学龄前儿童右眼散光度数上升幅度均较左眼大(P<0.001)。2018~2021年,纳入学龄前儿童双眼散光患病率与散光度数变化趋势基本一致。结论:广州市白云区学龄前儿童在1岁内散光度数最高、进展速度最快。新冠疫情前学龄前儿童散光度数及患病率相对稳定;新冠疫情期间散光度数及患病率出现较大幅度上升,且右眼散光度数上升幅度较左眼大;新冠疫情常态化防控后,散光度数及患病率明显下降。AIM:To explore the characteristics of astigmatism in preschool children before,during and after the COVID-19 epidemic,so as to provide a reference for further prevention and control of children’s vision.METHODS:In the consecutive four years from January 2018 to December 2021,a retrospective analysis of vision data was conducted on 2273 preschool children(4546 eyes)younger than 4 years old who participated in children’s vision screening test in Baiyun district,Guangzhou.They were divided into 1-year old group(ages<1-year old,420 cases),2-year old group(1-year≤ages<2-year,543 cases),3-year old group(2-year≤ages<3-year,614 cases),and 4-year old group(3-year≤ages<4-year,696 cases)according to ages.The analysis included astigmatic degrees of children’s eyes as well as their conditions of astigmatism.RESULTS:In 2018,the astigmatic degrees of the both eyes of 1-year-old group were higher than those of other groups(P<0.05).The binocular astigmatic degrees of the preschool children in four groups were obviously higher in 2020 than 2019(P<0.05),while they were significantly decreased in 2021 when compared with 2020(P<0.05).From 2019 to 2020,the increase of astigmatic degrees of the right eye is more considerable than the left eye of preschool children in those four groups(P<0.001).Furthermore,the morbidity of astigmatism basically echoes with the changing tendency of astigmatic degrees from 2018 to 2021.CONCLUSIONS:Preschool children in Baiyun district,Guangzhou,have the highest degree of astigmatism and the fastest progression rate within 1 year old.Before COVID-19 epidemic,the changes in astigmatism and prevalence were relatively stable;during COVID-19 epidemic,the astigmatism and prevalence increased significantly and the astigmatic degrees of right eye increased more than that of the left eye;after the normalization of epidemic prevention and control,the astigmatism and prevalence decreased significantly.
