Objective: Myopia prevalence mostly affects young people, particularly in Asia. Of the several recommendations addressing the myopia epidemic, auricular acupoint stimulation has been proposed and investigated. However, reported outcomes have been inconsistent, prompting a meta-analysis to obtain more precise estimates.
Materials and Methods: Twelve articles were included in a meta-analysis, wherein each article was evaluated for risk of bias. Summary effects were calculated using odds ratios (ORs) and 95% confidence intervals (CIs). Outlier and sensitivity treatments as well as publication bias assessment were applied.
Results: Risk of bias among the articles was low in random sequence but generally unclear judgments for the other bias criteria. AAS outcomes were significant (Pa [P-value for association] <0.00001-0.003) when random and fixed effects favored the treated groups (ORs: 2.87-3.42; 95% CIs: 1.44-5.75).
Conclusions: This meta-analysis showed evidence of auricular acupoint stimulation being effective for controlling myopia. Substantial magnitude (up to 3.4-fold), robustness, and lack of bias strengthened this effect.
