Radial 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 کاملOptic nerve head drusen.
Optic disc drusen are congenital and developmental anomalies of the optic nerve head seen commonly in clinical practice, often as an incidental ophthalmologic finding during routine exams. Optic disc drusen are a form of calcific degeneration in some of the axons of the optic nerve. Visual acuity is often not affected but the visual fields of these patients can be abnormal and deteriorate over ...
متن کاملRadial 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 کاملthe results of radial optic neurotomy for treatment of central retinal vein occlusion
central retinal vein occlusion (crvo) is the third most common blinding vascular retinal disorder. as there is no proven treatment for crvo, we performed this study to evaluate the effectiveness of radial optic neurotomy (ron) on visual acuity in eyes with crvo. this study was designed as an interventional case series. pars plana vitrectomy with ron was performed in 18 eyes of 16 patients with ...
