Abstract
Purpose: To describe a patient with retinal vasculitis after a single intravitreal injection (IVI) of pegcetacoplan. Methods: A case and its findings were analyzed. Results: An 80-year-old woman was treated with pegcetacoplan for subfoveal geographic atrophy. Ten days later, the patient noted “purple iridescent waves” but did not immediately report it. On day 18, she presented with pain and decreased visual acuity from 20/80 (pinhole) preinjection to 20/150 postinjection. No signs of inflammation were observed, and she was treated for high intraocular pressure (30 mm Hg). On day 23, iritis was noted. The fluorescein angiogram showed severe occlusive vasculitis involving all quadrants and the macula. The vasculitis/neuroretinitis laboratory panels were negative, and no contributing systemic features were identified other than well-controlled diabetes. Conclusions: In this patient, occlusive retinal vasculitis occurred shortly after a single IVI of pegcetacoplan.
