Most studies found a statistically significant association between GLP-1 RA use and reduced glaucoma risk, with stronger effects observed with prolonged exposure in three studies. One preclinical study demonstrated that the GLP-1 RA NLY01 mitigated retinal neuroinflammation and protected ganglion cells in a mouse model. Proposed mechanisms include intraocular pressure (IOP) reduction, attenuation of oxidative stress, and direct neuroprotection <i>via</i> GLP-1 receptor activation. However, one Mendelian randomization study did not support a causal link.</p><p><strong>Conclusions: </strong>Current evidence suggests that GLP-1 RAs may confer a secondary benefit in reducing glaucoma risk, supported by both clinical and preclinical data. However, the predominance of retrospective studies, coupled with the lack of randomized controlled trials, limit causal inference. Further randomized controlled trials and mechanistic investigations are warranted to validate these findings and assess their translational potential in glaucoma prevention.</p><p><strong>How to cite this article: </strong>Lang MV, Vasu P, Dorairaj EA, <i>et al.</i> Glaucoma Risk Reduction as a Secondary Benefit of Glucagon-like Peptide-1 Receptor Agonists: A Review of Emerging Evidence.
