I read with interest the article by García-Arumí et al.1 Based on an uncontrolled study of radial opticneurotomy in 14 patients with nonischemic central retinal vein occlusion (CRVO),they conclude that radial optic neurotomy "improves or at least stabilizesthe course of severe" CRVO because of "decompression" and "by inducing newchorioretinal shunts."
From prospective studies of more than 600 patients with nonischemicCRVO during 30 years and from basic, experimental, and clinical research onthe optic nerve and CRVO, I find their conclusions misleading and the studyflawed. For example:
