The main limitation of the study by Danesh-Meyer et al. was neither discussed nor mentioned. The time axis was not taken into account. The functional change after an acute event such as anterior ischemic optic neuropathy (AION) is immediate, but there is a delay before the anatomic changes take place. In this study, most of the patients with nonarteritic anterior ischemic optic neuropathy (NAIO...

PURPOSE To evaluate electrically evoked phosphene thresholds (EPTs) in healthy subjects and in patients with retinal disease and to assess repeatability and possible correlations with common ophthalmologic tests. METHODS In all, 117 individuals participated: healthy subjects (n = 20) and patients with retinitis pigmentosa (RP, n = 30), Stargardt's disease (STG, n = 14), retinal artery occlusi...

Ischemic optic neuropathies could be a result of inflammatory and non inflammatory small vessel disease and have been classified as arteritic and non-arteritic anterior ischemic optic neuropathy respectively. This review has been intended to elucidate the epidemiology, etiology, pathogenesis, clinical picture and management of NAION and the literature search was completed using the published da...

purpose: to evaluate the effect of levodopa-carbidopa on improvement of visual acuity, color vision, and visual field in patients with nonarteritic anterior ischemic optic neuropathy (naion) with onset less than 6 wks. methods: in this double-blind randomized controlled trial, 13 patients were treated with levodopa-carbidopa and 12 patients were treated with placebo for 3 weeks. after 6 months,...

Q. What conditions comprise ocular thrombosis? CJG Ocular thrombosis includes central and branch retinal vein occlusion (CRVO), central retinal artery occlusion (CRAO), amaurosis fugax (AF), and non-­arteritic ischemic optic neuropathy (NAION), all of which are closely related to coagulation abnormalities. In the United States, branch and central retinal rein occlusions are the second most comm...
