Radial Optic Neurotomy: A New Surgical Approach for Glaucoma Treatment?
Glaucoma is a leading cause of blindness worldwide, characterised by specific visual field defects due to the degeneration of retinal ganglion cells and damage to the optic nerve head (ONH). Elevated intraocular pressure (IOP) is the most important risk factor for glaucoma development. One of the clinical hallmarks of glaucomatous optic neuropathy is the excavation of the ONH, which consists of...
متن کاملRadial Optic Neurotomy for Central Retinal Vein Occlusion
PURPOSE Surgical decompression of the vein in central retinal vein occlusion (CRVO) by radial optic neurotomy (RON) was recently proposed as being surgically feasible, safe, and beneficial. The effect of RON on the visual field has not been systematically reported, although possible visual field defects are expected due to iatrogenic cutting of the optic nerve fibers. The authors report the res...

متن کاملRadial optic neurotomy as a treatment for anterior ischemic optic neuropathy secondary to optic disc drusen
IMPORTANCE Radial optic neurotomy (RON) was first described by Opremcak as a treatment for patients with central retinal vein occlusion (CRVO). The most common cause of visual loss in patients with optic disc drusen is nonarteritic anterior ischemic optic neuropathy (NAION). The pathogenesis of nonarteritic anterior ischemic optic neuropathy associated with optic disc drusen is assumed to be si...
متن کاملFundus and histopathological study of radial optic neurotomy in the normal miniature pig eye.
OBJECTIVE To demonstrate the fundus and histopathological changes in the normal miniature pig eye after radial optic neurotomy. METHODS Ophthalmoscopic examinations, fundus photography, and fluorescein angiography were performed on 12 eyes that underwent radial optic neurotomy, 5 normal eyes, and 7 eyes that underwent vitrectomy (from 12 pigs in total) preoperatively and 1, 7, 14, 30, and 90 ...
