Introduction: The incidence of fellow eye involvement in non-arteritic anterior ischemic optic neuropathy (NAION) is 15% at 5 years after initial onset, although risk factors have not been identified. aim this article to determine the factor that could influence with NAION. Case Report: A 72 year-old male presented gradual painless vision loss left (LE) for 3 months. He did smoking habit. BCVA ...

Purpose. To compare optic disc topography performed by confocal laser ophthalmoscopy in eyes with nonarteritic anterior ischemic optic neuropathy (NAION), arteritic anterior ischemic optic neuropathy (AAION), and open-angle glaucoma (OAG), adjusting for the amount of retinal ganglion cell (RGC) loss, as measured by nerve fiber layer (NFL) thickness and average visual field loss. Methods. At fou...

Purpose: To evaluate the therapeutic effect of posterior sub-tenon methyl prednisolone in anterior ischemic optic neuropathy, No class 1 study has shown any conclusive medical or surgical treatment for non-arteritic anterior ischemic optic neuropathy (NAION). Efficacy of systemic or intravitreal steroids was suggested by some studies. This study was performed to evaluate the efficacy and safety...

purpose: to present a case of herpes zoster ophthalmicus (hzo) with consequent posterior ischemic optic neuropathy (pion). case report: a 58-year-old woman with a history of hzo in her right eye which was under treatment presented with loss of vision to no light perception. on examination, positive relative afferent pupillary defect was detected; however the optic disc was normal on ophthalmosc...

BACKGROUND Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, ...

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...
