Abstract

PURPOSE: To evaluate the 12-month follow-up results of intravitreal bevacizumab therapy for macular edema secondary to branch retinal vein occlusion and to identify the pretreatment factors that were associated with an improvement of the final visual outcome. METHODS: Fifty eyes of 50 patients with macular edema secondary to branch retinal vein occlusion received an injection of 1.25 mg/0.05 mL bevacizumab. Additional injections were done when recurrence of macular edema occurred or the treatment was not effective. The best-corrected visual acuity and foveal thickness were measured. Stepwise multiple regression analyses were also performed. RESULTS: The mean logarithm of the minimum angle of resolution visual acuity improved significantly from 0.53 to 0.26, and the mean foveal thickness decreased significantly from 523 to 305 μm during the 12-month follow-up period. The mean number of injections was 2.0 (range, 1-4). Stepwise multiple regression analyses showed that younger patients had both better visual acuity at 12 months and greater improvement of visual acuity during 12 months. In addition, better pretreatment visual acuity was associated with better visual acuity at 12 months but with less improvement of the visual acuity. CONCLUSION: Intravitreal bevacizumab therapy can be a long-term effective treatment for macular edema secondary to branch retinal vein occlusion.
