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...

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 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 hypoparathyroidism might cause various musculoskeletal findings, resembling spondyloarthropathies. case presentation we described a 52-year-old woman, diagnosed as a case of undifferentiated spondyloarthropathy for ten years, who was unresponsive to classic anti-inflammatory therapies. she developed anterior ischemic optic neuropathy and had elevated muscle enzymes during the cours...

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...

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...
