Mild Bilateral Hemorrhagic Occlusive Retinal Vasculitis Following Intracameral Vancomycin Administration in Cataract Surgery.

A patient underwent cataract surgery with prophylactic intracameral vancomycin (Vancocin; Pfizer, New York City, NY) in each eye, 2 weeks apart. Four weeks after, the patient presented with a mild bilateral hemorrhagic occlusive retinal vasculitis (HORV). A systemic work-up was negative for syphilis, toxoplasmosis, Bartonella, tuberculosis, and sarcoidosis. The patient was treated with oral steroids and one intravitreal steroid injection in the left eye. Ten months after presentation, the patient's vasculitis was quiescent. Although the literature describes primarily severe forms of HORV, the authors' case describes bilateral, mild HORV and highlights the potential underreporting of these cases in the literature.
