Metformin and Age-Related Macular Degeneration: Current Evidence on Development and Progression
Highlights
- Large cohort studies using electronic health records found no significant association of metformin with reduced development or progression of AMD overall.
- Prolonged metformin use (≥5 years) in diabetic populations shows a potential protective effect against incident AMD in some observational studies.
- Meta-analyses report a modest reduction in AMD prevalence among metformin users, but high heterogeneity and confounding limit definitive conclusions.
- Randomized clinical trial data on metformin for geographic atrophy progression remain inconclusive, underscoring the need for further prospective research.
