Objective To observe the therapeutic effect of radial optic neurotomy (RON) for ischemic central retinal vein occlusion (CRVO) with macular edema. Methods The clinical data of 6 patients with ischemic CRVO combined with macular edema who had been treated with vitrectomy and radial optic neurotomy were retrospectively analyzed. The pre- and post-operative visual acuity, results of fundus fluorescein angiography (FFA) and optic coherence tomography (OCT), including the macular thickness, fluorescein filling in retinal veins, retinal hemorrhages and papilloedema were analyzed and compared. Results In the 6 patients, the visual acuity increased in different degrees and retinal hemorrhages decreased evidently. Macular edema was alleviative in 5 patients, retinal vein dilatation meliorated in 4, and papilloedema disappeared in 2. Conclusion RON may alleviate macular edema in patients with ischemic CRVO, but the relation of the therapeutic effect and vitrectomy can not be eliminated. (Chin J Ocul Fundus Dis, 2005,21:3-5)
