PURPOSE: To describe a patient with a central retinal vein occlusion (CRVO) who developed central retinal artery occlusion after radial optic neurotomy. DESIGN: Interventional case report. METHODS: A 70-year-old woman with CRVO underwent a radial optic neurotomy on her right eye. Her preoperative visual acuity in the affected eye was 20/400. RESULTS: Radial optic neurotomy was performed after phacoemulsification and aspiration for a cataract with intraocular lens implantation. At the insertion of a CRVO knife, pulsating bleeding occurred from the cup of the optic disk; the bleeding was stopped within 2 minutes by elevating the intraocular pressure to 80 mm Hg. On the following day, the patient noticed that she had lost light perception. Fluorescein angiography showed a marked delay of arterial filling, indicating a central retinal artery occlusion. Retinal circulation returned to normal 2 months later; however, her vision was still no light perception. CONCLUSIONS: Ophthalmologists should be aware that se, vere complications such as central retinal artery occlusion can be associated with radial optic neurotomy, which is an unproven surgical procedure with a questionable pathophysiologic mechanism.
