Abstract
Purpose: To describe a case of endophthalmitis caused by Haemophilus influenzae, an encapsulated bacterium, after intravitreal (IVT) injection of pegcetacoplan. Methods: A single retrospective case was evaluated. Results: An 88-year-old woman with a history of diabetes mellitus, on dialysis for chronic kidney disease, hypertension, hypothyroidism, diffuse large B-cell lymphoma, and geographic atrophy in both eyes received an IVT injection of pegcetacoplan in both eyes. She subsequently developed endophthalmitis in the right eye caused by H influenzae. Further bloodwork showed Proteus mirabilis bacteremia. Conclusions: Pegcetacoplan, a complement inhibitor, may be associated with intraocular infections with encapsulated organisms, especially in immunocompromised patients.
