摘要
目的 评价视觉训练对近视儿童的干预效果,为儿童近视干预提供依据.方法 选择2021年在舟山医院眼科门诊就诊的90例8～10岁近视儿童为研究对象,随机分为对照组、干预1组和干预2组,每组30例;对照组实施医学配镜,干预1组实施医学配镜和视觉训练联合,干预2组仅视觉训练.通过问卷收集研究对象的基本信息、最佳矫正视力和斜视度等资料;分别在干预前和干预后(1、3、6和12个月)测量等效球镜度、正负相对调节、调节幅度和调节灵活度等指标,采用重复测量资料的方差分析比较3组干预效果.结果 3组儿童性别、年龄、睡眠时间、父母近视情况、户外活动时间、最佳矫正视力和斜视度比较,差异无统计学意义(均P＞0.05).重复测量资料的方差分析结果显示,3组近视儿童的等效球镜度、正负相对调节、调节幅度和调节灵活度指标的组间差异无统计学意义,且组间与时间不存在交互效应(均P>0.05);3组近视儿童的等效球镜度、正负相对调节、调节幅度和调节灵活度在不同干预时间的比较,差异有统计学意义,干预6、12个月后,干预1组和干预2组近视儿童等效球镜度、正负相对调节、调节幅度和调节灵活度高于干预前和干预1、3个月(均P<0.05).结论 视觉训练对近视儿童有一定效果,但未发现医学配镜、医学配镜和视觉训练联合对近视儿童干预效果存在差异.
Abstract
Objective To evaluate the effect of visual training on children with myopia,so as to provide the evidence for the intervention of children with myopia.Methods Ninety myopic children aged 8 to 10 years who visited the ophthalmology outpatient department of Zhoushan Hospital in 2021 were selected,and randomly divided into a control group,an intervention group 1,and an intervention group 2,with 30 cases in each group.The control group received medical glasses prescription,the intervention group 1 received a combined intervention of medical glasses prescription and visual training,and the intervention group 2 received only visual training intervention.Basic information,best cor-rected visual acuity and strabismus degree were collected through questionnaire surveys.Equivalent spherical lens pow-er,positive and negative relative accommodation,amplitude of accommodation,and accommodative facility were mea-sured before and after 1 month,3 months,6 months and 12 months intervention.The intervention effects among the three groups were compared using variance analysis of repeated-measures analysis of variance.Results There were no significant differences in gender,age,sleep time,parents'myopia status,outdoor activity time,best corrected visual acu-ity and strabismus degree among the three groups of children(all P>0.05).The results of analysis of variance for re-peated measures revealed no significant differences in spherical equivalent,positive/negative relative accommodation,ac-commodation of amplitude,and accommodative facility among three groups of myopic children,with no interaction be-tween groups and time(all P>0.05).Significant differences in these parameters were noted across the intervention times within each group(P<0.05).After 6 and 12 months of intervention,the spherical equivalent,positive/negative rel-ative accommodation,amplitude of accommodation,and accommodative facility of the myopic children in the interven-tion group 1 and intervention group 2 were higher than those before intervention and at 1 and 3 months of interven-tion(all P<0.05).Conclusions Visual training has certain effect on myopia children.However,no differences were found in the intervention effects of medical glasses prescription alone,or when combined with visual training on myo-pia children.
