Outdoor activities were restricted during the COVID-19 outbreak, although digital learning grew. Concerns have been raised about the impact of these environmental changes on myopia status. This research aimed to examine myopia shift during the COVID-19 pandemic and offer the community evidence-based data.
The literature search was undertaken in PubMed, SCOPUS, Science Direct, Web of Science and Google Scholar databases on published papers before 17 May 2022. The main outcome was mean spherical equivalent refraction (SER) before, at the onset and at the end of follow-up during the COVID-19 pandemic.
Among 518 articles, 10 studies were included in the meta-analysis. The mean SER differences during the COVID-19 pandemic follow-up (mean follow-up time was 10 months) compared with before the pandemic was 0.15 dioptre (D) (95% CI -0.39 to 0.69, p=0.58). After age adjustment using meta-regression, the mean SER differences during the COVID-19 follow-up compared with before the pandemic was - 0.46 D (95% CI -0.59 to -0.34, p<0.001). Over the mean follow-up time during the COVID-19 pandemic, the SER mean difference was -0.55 D (95% CI -0.78 to -0.32, p<0.001), showing that the mean SER had decreased significantly during the COVID-19 pandemic. The mean SER differences in myopic patients before COVID-19 compared with during the pandemic follow-up was -0.49 D (95% CI -0.53 to -0.45, p=0.00). So the prior pandemic myopic patients became more myopic during the pandemic follow-up time.
During home quarantine, the mean SRE shifting in paediatrics accelerated. This phenomenon should be given more attention by policymakers, eyecare experts, educators and parents.
尽管数字学习有所发展，但 COVID-19 疫情期间户外活动受到限制。人们对这些环境变化对近视状况的影响表示担忧。本研究旨在探讨 COVID-19 大流行期间近视的变化情况，并为社区提供循证数据。
在 2022 年 5 月 17 日之前，我们在 PubMed、SCOPUS、Science Direct、Web of Science 和 Google Scholar 数据库中对已发表的论文进行了文献检索。主要结果是 COVID-19 大流行期间随访期间平均球镜等效屈光度（SER）的平均值。
在 518 篇文章中，有 10 项研究纳入荟萃分析。与大流行前相比，COVID-19 大流行随访期间（平均随访时间为 10 个月）的平均 SER 差异为 0.15 屈光度（D）（95%置信区间 -0.39 至 0.69，p=0.58）。使用荟萃回归进行年龄调整后，COVID-19 随访期间与大流行前相比，平均 SER 差异为-0.46 D（95%置信区间 -0.59 至 -0.34，p<0.001）。在 COVID-19 大流行期间的平均随访期间，SER 平均差异为-0.55 D（95%置信区间 -0.78 至 -0.32，p<0.001），表明 SER 平均值在 COVID-19 大流行期间显著下降。与 COVID-19 大流行前相比，COVID-19 大流行随访期间近视患者的平均 SER 差异为-0.49 D（95%置信区间 -0.53 至 -0.45，p=0.00）。因此，先前患有近视的患者在大流行随访期间变得更加近视。
在家隔离期间，儿科患者的平均 SRE 变化加速。这一现象应该引起政策制定者、眼保健专家、教育工作者和家长的更多关注。
