Purpose: We report a case of topical corticosteroid treatment-resolved rubeosis iridis with neovascular glaucoma (NVG) caused by noninfectious granulomatous uveitis. Case Report: A 61-year-old woman with left ocular pain and blurred vision was referred to our department. Visual acuity and intraocular pressure (IOP) were 20/60 and 37 mm Hg in the left eye, respectively. Inflammatory cells, hyphema, and rubeosis iridis were observed. All laboratory tests, including multiplex polymerase chain reaction for infection using aqueous humor, were negative, and there was neither retinal occlusive vasculitis nor retinal ischemia in the fundus. Our diagnosis was noninfectious granulomatous anterior uveitis-associated NVG. Topical corticosteroid treatment and anti-glaucoma agents resolved inflammation, rubeosis iridis, and NVG. IOP had decreased to 13 mm Hg by 1 month of treatment, and no recurrence was observed. Conclusion: Topical corticosteroid could resolve rubeosis iridis and NVG in an eye with noninfectious anterior uveitis. The pathogenesis of NVG in eyes with uveitis is still unknown, but inflammation might have a part in angiogenesis. Anti-inflammatory treatment can be selected as the first choice for anterior uveitis-associated NVG.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains a serious pandemic. COVID-19 vaccination is urgent needed for limiting SARS-CoV-2 outbreaks by herd immunity. Simultaneously, post-marketing surveillance to assess vaccine safety is important, and collection of vaccine-related adverse events has been in progress. Vision-threatening ophthalmic adverse events of COVID-19 vaccines are rare but are a matter of concern. We report a 45-year-old Japanese male with positive for HLA-DR4/HLA-DRB1*0405, who developed bilateral panuveitis resembling Vogt-Koyanagi-Harada (VKH) disease after the second dose of Pfizer-BioNTech COVID-19 mRNA (BNT162b2) vaccine. Glucocorticosteroid (GC) therapy combined with cyclosporine A (CsA) readily improved the panuveitis. The immune profile at the time of onset was analyzed using CyTOF technology, which revealed activations of innate immunity mainly consisting of natural killer cells, and acquired immunity predominantly composed of B cells and CD8+ T cells. On the other hand, the immune profile in the remission phase was altered by GC therapy with CsA to a profile composed primarily of CD4+ cells, which was considerably similar to that of the healthy control before the vaccination. Our results indicate that BNT162b2 vaccine may trigger an accidental immune cross-reactivity to melanocyte epitopes in the choroid, resulting in the onset of panuveitis resembling VKH disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
