To report our initial experience with radial optic neurotomy (RON) as a treatment for central retinal vein occlusion (CRVO). A prospective, uncontrolled, interventional study of nine patients was analyzed. A three-port standard pars plana vitrectomy with RON was performed in all patients. Patients were followed postoperatively with standard ocular examinations including visual acuity and fundus examinations after 1 day, 1 week, 1 month, 2 months, and at the last visit. RON was performed successfully in all 9 patients, with complications of mild vitreous hemorrhage and limited hematoma of the optic nerve head in 2 patients. These complications resolved within 2 months. From clinical observations of these patients, we noted that RON accelerated the resolution of macular edema and intraretinal hemorrhage. Postoperative visual acuity was unchanged or improved in all patients. Five of the patients had a rapid improvement in final visual acuity of 6/60 or better. Three of the patients had dramatic improvement in their visual acuity of 6/10 or better. Surgical decompression via RON may improve visual acuity in eyes with CRVO, although postoperative complications such as vitreous hemorrhage or hematoma of the optic nerve head may occur. A randomized, controlled multicenter study should be conducted to determine the efficacy of RON in the treatment of CRVO and to further examine the possibility of severe complications.
