Non-arteritic anterior ischemic optic neuropathy is one of the most common conditions affecting the optic nerve in the elderly. It may lead to severe visual loss. Typical symptoms are painless impairment of visual function accompanied by relative afferent pupillary defect, edema of the optic disc and visual field defects. Aim is to present 38 patients with nonarteritic anterior ischemic optic n...

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...

A 46-year-old Caucasian female underwent pars plana vitrectomy (ppv) for retinal detachment. After the procedure, the patient could only distinguish hand movements; the condition was tentatively diagnosed as nonarteritic anterior ischemic optic neuropathy. Conventional treatment with systemic corticosteroids and acetylsalicylic acid was ineffective and yielded substantial steroid-related side e...

PURPOSE To evaluate the accuracy and generalizability of a published model that derives estimates of retinal ganglion cell (RGC) counts and relates structural and functional changes due to glaucoma. METHODS Both the Harwerth et al. nonlinear model (H-NLM) and the Hood and Kardon linear model (HK-LM) were applied to an independent dataset of frequency-domain optical coherence tomography and vi...

in patients with nonarteritic anterior ischemic optic neuropathy. Differential diagnosis of concentric visual field defects using electrophysiological methods. patterns of cone degeneration in retinitis pigmentosa with concentric narrowing of the visual field. electroretinograms and visual evoked potentials in retinitis pigmentosa. Documenta of multifocal electroretinograms obtained under monoc...

Purpose Diabetes mellitus (DM) is one of the most important risk factors for nonarteritic anterior ischemic optic neuropathy (AION). In this study, we investigated for the first time the impact of experimental AION in a DM model. Methods We induced a photochemical thrombosis model of AION after streptozotocin-induced DM and performed serial optical coherence tomography (OCT), morphometric ana...

INTRODUCTION We report on three cases of visual loss due to nonarteritic anterior ischemic optic neuropathy that developed during the course of refractory anemia, a subtype of myelodysplastic syndrome. PATIENTS AND METHODS Patients underwent fundus, visual field examination, and fluorescein angiography. A thrombophilic tendency investigation including prothrombin time, partial thromboplastin ...

OBJECTIVE To evaluate the pattern of various types of visual field defects and their prevalence at initial examination of nonarteritic anterior ischemic optic neuropathy (NA-AION). METHODS The data were compiled from 312 consecutive eyes (in 265 patients) that fulfilled our inclusion and exclusion criteria. A comprehensive ophthalmic evaluation was performed, including recording of visual acu...

BACKGROUND There have been anecdotal reports of anterior ischemic optic neuropathy (AION) occurring in eyes with optic disc drusen (ODD), but the clinical features of this condition have not been well characterized. OBJECTIVES To better describe the clinical features of AION associated with ODD and to compare the clinical features of this condition with those of "garden variety" nonarteritic ...

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 ...
