PURPOSE: To evaluate the efficacy of intravitreal bevacizumab for prevention of macular edema after plaque radiotherapy of uveal melanoma. DESIGN: Retrospective, single-center, nonrandomized, interventional comparative study. PARTICIPANTS: Patients with uveal melanoma treated with plaque radiotherapy were divided into 2 groups: a bevacizumab group and a control group. INTERVENTION: The bevacizumab group received intravitreal bevacizumab injection at the time of plaque removal and every 4 months thereafter for 2 years (total, 7 injections). The control group had no intravitreal bevacizumab injection. Both groups had periodic follow-up with ophthalmoscopy and optical coherence tomography (OCT). MAIN OUTCOME MEASURES: Development of OCT-evident macular edema. RESULTS: There were 292 patients in the bevacizumab group and 126 in the control group. The median foveolar radiation dose was 4292 cGy (bevacizumab) and 4038 cGy (control; P = 0.327). The cumulative incidence of OCT-evident macular edema over 2 years (bevacizumab group vs. control group) was 26% versus 40% (P = 0.004), respectively; that for clinically evident radiation maculopathy was 16% versus 31% (P = 0.001), respectively; that for moderate vision loss was 33% versus 57% (P < 0.001), respectively; and that for poor visual acuity was 15% versus 28% (P = 0.004), respectively. There was no statistically significant difference in clinically evident radiation papillopathy (P = 0.422). Kaplan-Meier estimates at 2 years showed statistically significantly reduced rates of OCT-evident macular edema (P = 0.045) and clinically evident radiation maculopathy (P = 0.040) in the bevacizumab group compared with controls. CONCLUSIONS: Patients receiving intravitreal bevacizumab injection every 4 months after plaque radiotherapy for uveal melanoma demonstrated OCT-evident macular edema, clinically evident radiation maculopathy, moderate vision loss, and poor visual acuity less frequently over a period of 2 years than patients not receiving the injections.
