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...

purpose : to evaluate the effects of memantine on improving visual function in patients with acute nonarteritic anterior ischemic optic neuropathy (naion) methods : this was a prospective, double masked, randomized, clinical trial. the study involved 47 subjects with unilateral naion of less than 8 weeks duration. eligible patients were randomly allocated to take either memantine tablets (5 mg ...

BACKGROUND We conducted this study to report the demographics and clinical profile of patients with nonarteritic anterior ischemic optic neuropathy referred to a referral neuro-ophthalmology center in Iran. METHODS During a five-year period, 107 patients with nonarteritic anterior ischemic optic neuropathy were studied. A detailed history of previous or current systemic diseases was obtained ...

BACKGROUND AND PURPOSE The relation between anterior ischemic optic neuropathy and carotid artery atherosclerotic disease is unclear. We studied patients with anterior ischemic optic neuropathy to determine if they had an increased occurrence of carotid artery stenosis. METHODS Fifteen consecutive patients with anterior ischemic optic neuropathy were evaluated prospectively for cervical carot...

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...

Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common form of ischemic optic neuropathy and the second most common optic neuropathy. Patients are generally over the age of 50 years with vasculopathic risk factors (eg, diabetes mellitus, hypertension, and obstructive sleep apnea). The exact mechanism of NAION is not fully understood. In addition, several treatment options ha...
