Granulomatous anterior uveitis following mRNA-based COVID-19 vaccination: A case report

A 23-year-old patient presented with complaints of redness, pain, photophobia, and blurred vision in the right eye 15 days after she received the third dose of BNT162b2 vaccination. Ocular examination revealed 2+ cellular reactions in the anterior chamber and mutton fat keratic precipitate with no vitritis or retinal alterations. Active uveitis findings regressed with corticosteroid and cycloplegic eye drops. We present a case of unilateral granulomatous anterior uveitis following the BNT162b2 vaccination, with no etiologic factor in uveitis work-up and no previous history of uveitis before vaccination. This report demonstrates a potential causal association of coronavirus disease 2019 (COVID-19) vaccine with granulomatous anterior uveitis.
