The anterior ischemic optic neuropathy is an uncommon complication of alpha-Interferon treatment, characterized by the either temporary or permanent diminishing in visual acuity. We are hereby presenting the clinical case of an anterior ischemic optic neuropathy (non-arteritic form) complicating interferon therapy for Chronic Hepatitis C. In such cases we recommend ophthalmological examinations...

OBJECTIVES To determine whether early recognition and detection of thrombocytosis in patients with giant cell arteritis can help secure an earlier diagnosis, and whether it can help differentiate cases of arteritic optic neuropathy from other forms of optic neuropathy. METHODS Medical and ophthalmologic records from 1993 to 1998 of the authors' patients with biopsy-proven temporal arteritis v...

PURPOSE To describe a case of non-arteritic ischemic optic neuropathy (NAION) secondary to acute primary-angle closure (APAC). METHODS Case report. RESULTS A 50-year-old woman with painful visual loss in the right eye was found to be in APAC with a right afferent pupillary defect. Laser peripheral iridotomy relieved pain but did not improve vision. Diffuse optic disc edema in the right eye ...

PURPOSE To evaluate the optic disc area of patients with non-arteritic anterior ischemic optic neuropathy (NA-AION) and arteritic anterior ischemic optic neuropathy (A-AION) and compare the results between each other and with those from controls in order to verify the existence and the magnitude of anatomical factors predisposing to the development of anterior ischemic optic neuropathy. METHO...

Introduction The aim was to study the risk of non arteritic ischemic optic neuropathy after phacoemulsification cataract surgery. Methods This study was conducted at King Hussein Medical Center during the period between January 2015 and July 2016. Patients attending ophthalmology clinic complaining of decreased vision due to lens opacity were evaluated. Patients were divided into two groups. ...

INTRODUCTION An "overlap syndrome" is defined as the sequential appearance over time of two or more risk factors for glaucomatous damage. The appearance of a new risk factor can alter the course and prognosis of previously stable disease. Exfoliation syndrome is a leading cause of glaucoma and is associated with vascular disease. We report a case of central retinal artery occlusion and non-arte...

purpose: to evaluate the role of transvitreal optic neurotomy (ton) in the management of non-arteritic anterior ischemic optic neurotomy (naion). methods: sixteen eyes of 16 patients with recent onset naion (less than six weeks duration) were included in this single-masked randomized controlled trial. the patients were randomized to ton (8 eyes) versus observation alone (8 eyes). pre- and posto...

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...
