BACKGROUND
Daily "eye exercises," massaging of periocular acupuncture pressure points, have been part of China's national vision care policy in schools for some 50 years. However, the effect of eye exercises on myopia progression and eyeglasses wear has not been definitively investigated. This study evaluates the effectiveness of eye exercises on visual acuity and the propensity of rural children to wear eyeglasses.
METHODS
Cohort study in 252 randomly-selected rural schools with baseline in September 2012 and follow up surveys 9 and 21 months later. Outcomes were assessed using propensity-score matching (PSM), multivariate linear regression and logistic regression to adjust for differences between children performing and not performing eye exercises.
RESULTS
Among 19,934 children randomly selected for screening, 2374 myopic (spherical equivalent refractive error ≤ - 0.5 diopters in either eye) children (11.9%, mean age 10.5 [Standard Error 1.08] years, 48.5% boys) had VA in either eye ≤6/12 without eyeglasses correctable to > 6/12 with eyeglasses. Among these who completed the 21-month follow up, 1217 (58.2%) children reported practicing eye exercises on school days and 874 (41.8%) did not. After propensity-score matching, 1652 (79%) children were matched: 826 (50%) in the Eye Exercises group and 826 (50%) in the No Exercise group. Performing eye exercises was not associated with change in LogMAR uncorrected visual acuity and wear of eyeglasses, using either logistic regression or PSM at 9 or 21 months.
CONCLUSIONS
We found no evidence for an effect of eye exercises on change in vision or eyeglasses wear.

背景
每天进行“眼保健操”，按摩眼周穴位，是中国近 50 年来学校视力保健政策的一部分。然而，眼保健操对近视进展和戴眼镜的影响尚未得到明确证实。本研究评估眼保健操对视力和农村儿童戴眼镜倾向的影响。
方法
在 2012 年 9 月进行的 252 所农村学校的队列研究中，在基线和 9 个月和 21 个月后进行了随访调查。采用倾向评分匹配（PSM）、多元线性回归和逻辑回归来调整进行眼保健操和不进行眼保健操的儿童之间的差异，对结果进行评估。
结果
在随机选择的 19934 名儿童中，有 2374 名近视儿童（双眼等效球镜屈光不正值≤-0.5 屈光度）（11.9%，平均年龄 10.5[标准误差 1.08]岁，48.5%男孩）的视力未矫正视力在双眼均≤6/12，未矫正视力用眼镜可矫正至>6/12。在完成 21 个月随访的这些儿童中，有 1217 名（58.2%）儿童报告在上学日进行眼保健操，有 874 名（41.8%）儿童未进行。经过倾向评分匹配后，有 1652 名（79%）儿童进行了匹配：826 名（50%）在眼保健操组，826 名（50%）在无运动组。使用逻辑回归或 PSM 在 9 个月或 21 个月时，进行眼保健操与 LogMAR 未矫正视力的变化和戴眼镜之间均无关联。
结论
我们没有发现眼保健操对视力或戴眼镜的变化有任何影响。
