Efficacy of single bevacizumab injection as adjuvant therapy to laser photocoagulation in macular edema secondary to branch retinal vein occlusion

摘要

BackgroundMacular grid laser photocoagulation remains the standard treatment for macular edema secondary to branch retinal vein occlusion (BRVO). One possible strategy for treating macular edema is to inhibit VEGF activity by competitive binding of VEGF with an anti-VEGF antibody, suggesting the therapy option with bevacizumab. However, multiple injections of anti-VEGF may lead to complications and high cost.
