摘要

目的：观察对比COVID-19疫情爆发前后1 年西安市第一医院6～12 岁儿童中低度近视的进展情况。

方法：回顾性病例对照研究。收集COVID-19疫情爆发前（2018 年12 月至2019 年1 月，疫情前组）和

爆发后（2019 年12 月至2020 年1 月，疫情后组）就诊于西安市第一医院眼科的6～12 岁双眼近视儿

童各100 例（200 眼），纳入具有半年和1 年随访记录者。分析2 组患者基线、半年随访及1 年随访的

眼轴长度（AL）、等效球镜度（SE）、眼轴/角膜曲率比值（AL/CR）的变化情况。数据采用独立样本

t检验进行比较。结果：疫情前组100 例（200 眼），男42 例，女58 例，年龄（9.6±1.2）岁；疫情后组

100 例（200 眼），男49 例，女51 例，年龄（9.2±2.4）岁。在半年随访时，疫情前组AL增长为（0.27±

0.16）mm，疫情后组AL增长幅度较大，为（0.36±0.19）mm，2 组差异有统计学意义（t=-6.228，

P<0.001）；疫情后组SE[（-0.48±0.37）D vs. （-0.74±0.63）D，t=-2.375，P<0.001]及AL/CR（0.017±0.028

vs. 0.029±0.031，t=-6.052，P<0.001）的增长幅度均明显大于疫情前组。1 年随访时，疫情前组AL

增长为（0.46±0.31）mm，疫情后组AL增长幅度更加明显，为（0.61±0.24）mm，2 组差异有统计学

意义（t=1.138，P<0.001）；疫情后组SE[（-0.90±0.41）D vs.（ -1.25±0.48）D，t=7.253，P<0.001]及

AL/CR（0.030±0.051 vs. 0.046±0.036，t=5.049，P=0.032）的增长幅度均明显大于疫情前组。结论：

COVID-19疫情爆发后西安市第一医院门诊就诊的6～12 岁学龄段儿童近视进展速度较疫情前更快，

主要表现在AL、SE和AL/CR方面。

Abstract：

Objective: To compare the progression of low to moderate myopia in children 6-12 years of age in

the Xi'an First Hospital before and after the COVID-19 epidemic. Methods: This was a retrospective

cohort study. One hundred cases (200 eyes) of children 6-12 years of age with binocular myopia who

were admitted to the Department of Ophthalmology in Xi'an No.1 Hospital before the outbreak of the COVID-19 epidemic (December 2018 to January 2019) and after the outbreak (December 2019 to January

2020) participated in the study. Follow-up records were recorded for 0.5 and 1 year. The mean age of the

pre-epidemic group was 9.6±1.2 years, and the mean age of the post-epidemic group was 9.2±2.4 years.

Changes in the ocular axis (AL), spherical equivalent (SE) and axial/corneal curvature ratio (AL/CR) at

baseline, 0.5 and 1 year were retrospectively analyzed in the 2 groups, and the data were compared by a

paired t test. Results: At the 0.5 year follow-up, the pre-epidemic group showed less AL growth than the

post-epidemic group (0.27±0.16 mm vs. 0.36±0.19 mm) (t=-6.228, P<0.001), an increase in SE (-0.48±

0.37 D vs. -0.74±0.63 D) (t=-2.375, P<0.001), and an increase in AL/CR ratio (0.017±0.028 vs.

0.029±0.031) (t=-6.052, P<0.001). At the 1 year follow-up, the pre-epidemic group showed less AL growth

than the post-epidemic group (0.46±0.31 vs. 0.61±0.24) (t=1.138, P<0.001), an increase in SE (-0.90±

0.41 D vs. -1.25±0.48 D) (t=7.253, P<0.001), and an increase in the AL/CR ratio (0.030±0.051 vs.

0.046±0.036) (t=5.049, P=0.032). Conclusions: After the outbreak of COVID-19, the progression of

myopia in 6-12 year-old school-age children in the post-epidemic is faster than in the pre-epidemic, mainly

manifested in AL, SE and AL/CR
