N2 - OBJECTIVE: To evaluate the short-term visual acuity and anatomic responses after intravitreal bevacizumab (Avastin, Genentech) treatment in patients with retinal angiomatous proliferation (RAP). METHODS: The authors conducted a retrospective review of consecutive patients with newly diagnosed or recurrent RAP treated with intravitreal bevacizumab (1.25 mg) during a 3-month period. Complete ocular examination was performed at baseline and follow-up visits. Interval data were analyzed statistically at 1 and 3 months follow-up. RESULTS: Twenty-three eyes of 23 patients underwent intravitreal bevacizumab treatment. The mean age of patients was 81.1 years, median baseline visual acuity of treated eyes was 20/80 (range 20/25-20/800), and mean baseline central macular thickness was 335 μm (optical coherence tomography was available for 22 eyes). Nine eyes had retinal pigment epithelial detachments (PEDs) at baseline. At 1-month follow-up, the median acuity improved to 20/60 (range 20/30-20/400) (P < 0.001), mean central macular thickness decreased to 202 μm (P < 0.001), and PED was present in only 2 eyes (P = 0.016). Seven of 23 eyes at 1 month (30.4%) had improved visual acuity, defined as halving of the visual angle, and no eyes had worse acuity, defined as doubling of the visual angle. Of the 17 eyes available for 3-month follow-up, 5 eyes (29.4%) had better visual acuity, 1 eye (5.9%) had worse acuity, and the remaining 11 (64.7%) had the same acuity. The median visual acuity at month 3 was 20/60 (range 20/25-20/400). There were no thromboembolic phenomena, endophthalmitis cases, retinal detachments, or any other adverse events. CONCLUSION: Treatment of RAP with intravitreal bevacizumab during this retrospective review resulted in a significant decrease in macular thickness and improvement or stabilization of visual acuity. Further long-term investigation is warranted given the promising short-term results.
