SURGICAL DECOMPRESSION OF BRANCH RETINAL VEIN OCCLUSION VIA ARTERIOVENOUS CROSSING SHEATHOTOMY: A Prospective Review of 15 Cases

Background: Branch retinal vein occlusion (BRVO), the second most common vascular disorder of the retina, typically occurs at arteriovenous (A/V) crossings where the arteriole and venule share a common adventitial sheath. Mechanical narrowing of the venous lumen at these intersections is thought to play a pathoetiologic role in BRVO. Methods: We performed surgical decompression of BRVO via A/V crossing sheatho- tomy in 15 patients with decreased...
