Ocular Adverse Events Induced by Immune Checkpoint Inhibitors: A Comprehensive Pharmacovigilance Analysis.

Characterize ocular adverse events (oAEs) caused by immune checkpoint inhibitors (ICIs). Retrospective analysis of 41,674 cancer patients in the FDA Adverse Event Reporting System (FAERS) pharmacovigilance database receiving anti-PD-1/PD-L1, anti-CTLA-4, or anti-PD-1+ anti-CTLA-4 combination. Reporting odds ratio (ROR) was used to approximate oAE rate across regimens and indications. The most common indications were lung cancer (27.3%) and melanoma (22.7%); 76.3% received anti-PD-1/PD-L1 monotherapy. 1,268 patients (3.0%) reported oAEs, namely vision disorders (30.8%), uveitis (15.1%), and retinal, lacrimal, and optic nerve disorders (10.7%, 9.0%, 8.4%). Melanoma showed the highest proportion of uveitis (117/9,471 cases; 1.2%). Addition of anti-CTLA-4 to anti-PD-1 increased the ROR of uveitis from 4.77 (95% CI 3.83–5.94) to 17.1 (95% CI 12.9–22.7). Among anti-PD-1/PD-L1 cases, uveitis was differentially reported in melanoma (ROR 14.7, 95% CI 10.7–20.2) compared with lung cancer (ROR 2.67, 95% CI 1.68–4.23). ICI-induced oAEs are rare, and uveitis is significantly associated with melanoma and anti-PD-1+ anti-CTLA-4 combination. [ABSTRACT FROM AUTHOR]
