Atopic dermatitis (AD) can present with open-angle glaucoma, but powerful evidence to support their causal relationship is absent. To investigate the causal association of AD with primary open-angle glaucoma (POAG). A bidirectional 2-sample Mendelian randomization (MR) study was performed with the software R. Eighteen single nucleotide polymorphisms (SNPs) were used in the forward MR analysis with AD as exposure. The inverse-variance weighted (IVW) method produced a result that genetically predicted AD was not associated with POAG (odds ratio [OR] = 1.10, 95% confidence interval [CI]: 0.95-1.27, = 0.215). Fifty-one SNPs were used in the reverse MR analysis with POAG as exposure. The IVW method yielded a result that genetically predicted POAG was not correlated with AD (OR = 0.98, 95% CI: 0.95-1.01, = 0.191). The bidirectional causal effect estimates were consistent with supplementary MR methods (MR-Egger, weighted median, simple mode, and weighted mode). The sensitivity analysis showed stable results. This bidirectional 2-sample MR study did not give evidence of causal association between AD and POAG.
