Summary: The aim of the study: Central retinal vein occlusion (CRVO) is one of the most common retinal vascular disorders and is often associated with significant visual loss. It is thought to arise from vascular obstruction at the level of lamina cribrosa. Radial optic neurotomy (RON) is an alternative treatment method for central retinal vein occlusion. Poor visual prognosis in patients with 0.1 or worse initial visual acuity is still a therapeutic challenge. RON may bye a beneficial surgical procedure for these patients. Authors present the RON procedure results of clinical study and own experience. Material and methods: Eleven eyes of 11 patients with central retinal vein occlusion lasting not longer than 3 months and with visual acuity Ł 0.1 underwent radial optic neurotomy. Results: Improvement of visual acuity was observed in 90% of operated cases. Four out of eleven patients developed chorioretinal venous anastomosis. No serious complications were noticed. Conclusion: Radial optic neurotomy can be beneficial for patients threatened with visual loss caused by central retinal vein occlusion. This procedure seems to be free from significant intra- and postoperative complications. However, in common with all previous reports, the current study is limited by the small number of patients included. Further randomized and controlled clinical studies are necessary to establish safety and efficacy of this technique.

Keywords: central retinal vein occlusion, radial optic neurotomy.
