colon; We performed a retrospective study of 103 cases of central retinal vein occlusion (CRVO) in young, nondiabetic adults that were followed for at least six months. Of these patients, 64% were men and 36% were women. While visual acuity was usually good, 33 eyes (32%) had a final visual acuity of 20/200 or worse, including 6 eyes (6%) with a final visual acuity of no light perception. Ocular complications included chronic cystoid macular edema, macular pigmentary changes (37%), sheathing of retinal vessels (22%), venous collaterals of the disc (33%), macular hole formation (1%), neovascularization of the disc (1%), retina (1%), and iris (19%), neovascular glaucoma (8%), and vitreous hemorrhage (7%).
