Intravitreal Injection of Brolucizumab for Recalcitrant Macular Edema due to Central Retinal Vein Occlusion: A Small Case Series

Abstract

This was a single center, prospective uncontrolled nonrandomized case series. Two eyes with recalcitrant ME secondary to CRVO, who have received a minimum of ten intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, underwent IVI brolucizumab (BRZ). Patients underwent best corrected visual acuity (BCVA) testing, ophthalmic examination, and optical coherence tomography at baseline and follow-up visits (weeks 4, 8, 12, and 16). Both patients demonstrated notable improvement in BCVA and reduction of fluid on SD-OCT lasting up to week 12. At week 16, though both the eyes maintained the visual acuity gains, early increase in fluid was noted in both cases, for which second dose of IVI BRZ was given. No ocular or systemic adverse events were noted in these 2 cases.
