 We performed radial optic neurotomy for central retinal vein occlusion in 11 eyes of 10 patients. The series comprised 5 eyes of 5 males and 6 eyes of 5 females. Their ages ranged from 53 to 79 years. Seven eyes were ischemic and 4 were nonischemic. There was a tendency for retinal hemorrhage and edema to be promptly absorbed after surgery. Eyes with persistent edema received subtenon injection of triamcinolone acetonide. Vitreous hemorrhage developed in 3 eyes soon after surgery. Neovascular glaucoma developed in 3 eyes. Panretinal photocoagulation was performed in 5 eyes. After follow-up for 5 months or longer,the final visual acuity ranged from hand motion to 0.9. There was no difference in the visual outcome between ischemic and nonischemic eyes. Radial optic neurotomy did not appear to be particularly effective for central retinal vein occlusion when compared with other therapeutic modalities.
