Chorioretinal Anastomosis After Radial Optic Neurotomy for Central Retinal Vein Occlusion

Abstract
CENTRAL RETINAL vein occlusion (CRVO) is the third most common blinding vascular retinal disorder1,2 after diabetic retinopathy and branch retinal vein occlusion. Among patients with CRVO, 34% develop capillary nonperfusion and retinal ischemia. Iris neovascularization and neovascular glaucoma may occur in 45% to 85% of the eyes affected by ischemic CRVO and only in 5% of the nonischemic eyes.2,3 The main known risk factors of CRVO are hypertension and open-angle glaucoma.2-5
