**Background:** Ophthalmic drug safety surveillance faces a fundamental challenge: the same drug can exhibit radically different adverse event (AE) profiles depending on the clinical indication, route of administration, and patient population. Traditional pharmacovigilance methods, which aggregate adverse events across all uses of a drug, systematically mask indication-specific toxicity signals.

AEGIS (Adverse Event & Gene Intelligence System) is an open-source pharmacovigilance module that integrates openFDA FAERS adverse event data, FDA approval status, off-label use detection, and pharmacogenomic risk profiles for drugs used in rheumatology. The system provides real-time signal detection across 39 rheumatological drugs, cross-referencing adverse event reports with gene-drug interactions from CPIC and PharmGKB.
