目的 研究配戴角膜塑形镜对儿童青少年初发单眼近视患儿双眼视功能的影响.方法 选取2022年1月至2023年1月西安市第四医院收治的80例初发单眼近视患儿为研究对象.所有患儿均配戴角膜塑形镜,比较配戴前与配戴1、3、6、9、12个月后近视眼与健侧眼的视功能.结果 配戴1、3、6、9、12个月后,初发单眼近视患儿的近视眼调节幅度、调节灵敏度、调节反应、正相对调节及负相对调节高于配戴前,差异具有统计学意义(P＜0.05).配戴1、3、6、9、12个月后,初发单眼近视患儿的近视眼聚散灵活度、集合近点高于配戴前,近视眼调节性集合/调节量(AC/A)低于配戴前,差异具有统计学意义(P＜0.05).配戴1、3、6、9、12个月后,初发单眼近视患儿的健侧眼调节幅度、正相对调节及负相对调节与配戴前比较,差异无统计学意义(P＞0.05);配戴3、6、9、12个月后,初发单眼近视患儿的健侧眼调节灵敏度、调节反应高于配戴前,差异具有统计学意义(P＜0.05).配戴1、3、6、9、12个月后,初发单眼近视患儿的健侧眼聚散灵活度高于配戴前,差异具有统计学意义(P＜0.05);配戴1、3、6、9、12个月后,初发单眼近视患儿的健侧眼集合近点、AC/A与配戴前比较,差异无统计学意义(P＞0.05).结论 配戴角膜塑形镜可明显改善儿童青少年初发单眼近视患儿近视眼视功能,提升健侧眼调节灵敏度、调节反应与聚散灵活度.
Abstract
Objective To study the effect of wearing orthokeratology lens on binocular visual function in children and adolescents with primary monocular myopia.Methods A total of 80 children with primary monocular myopia admitted in the Xi'an Fourth Hospital from January 2022 to January 2023 were selected as the research objects.All patients wore orthokeratology lens,and the visual function of myopic eyes and healthy eyes were compared before wearing and after 1,3,6,9 and 12 months after wearing.Results After 1,3,6,9 and 12 months of wearing,the accommodation amplitude,accommodation sensitivity,accommodation response,positive relative accommodation and negative relative accommodation of myopic eyes in children with primary monocular myopia were higher than those before wearing,and the differences were statistically significant(P＜0.05).After 1,3,6,9 and 12 months of wearing,the convergence and divergence flexibility and near point convergence of myopic eyes in children with primary monocular myopia were higher than those before wearing,the accommodation convergence/accommodation(AC/A)of myopic eyes was lower than that before wearing,and the differences were statistically significant(P＜0.05).After 1,3,6,9 and 12 months of wearing,there were no significant differences in the accommodation amplitude,positive relative accommodation and negative relative accommodation of healthy eyes in children with primary monocular myopia compared with those before wearing(P＞0.05);after 3,6,9 and 12 months of wearing,the accommodative sensitivity and accommodative response of healthy eyes in children with primary monocular myopia were higher than those before wearing,and the differences were statistically significant(P＜0.05).After 1,3,6,9 and 12 months of wearing,the convergence and divergence flexibility of healthy eyes in children with primary monocular myopia was higher than that before wearing,and the difference was statistically significant(P＜0.05);after 1,3,6,9 and 12 months of wearing,there were no significant differences in the near point convergence and AC/A of healthy eyes in children with primary monocular myopia compared with those before wearing(P＞0.05).Conclusion Wearing orthokeratology lens can significantly improve the visual function of myopia eye in children and adolescents with primary monocular myopia,and improve the accommodative sensitivity,accommodative response and convergence and divergence flexibility of the healthy eye.
