Branch Retinal Vein Occlusion Treatment Trial

This study is comparing two treatments for a condition called branch retinal vein occlusion (BRVO), where a smaller vein in the retina becomes blocked, causing vision loss due to swelling. The two treatments being compared are an injection of Bevacizumab (a drug that reduces abnormal blood vessel growth) into the eye, versus laser treatment (the current standard approach). The goal is to find out which treatment improves vision better. You may be eligible if: - You are 18 years or older - You have been diagnosed with branch retinal vein occlusion for at least 3 months - Your best corrected vision is worse than 20/40 in the affected eye - You have significant retinal swelling on imaging - Your kidney function is adequate You may NOT be eligible if: - You have had certain previous eye surgeries including glaucoma surgery or corneal transplant - You have had laser treatment to the affected area in the past month - You have active eye inflammation or infection - You are pregnant or breastfeeding - You have uncontrolled glaucoma Talk to your doctor about whether this trial might be right for you.
