PURPOSE Nonarteritic anterior ischemic optic neuropathy (NAION) results in optic nerve damage with retinal ganglion cell (RGC) loss. An NAION model, rodent anterior ischemic optic neuropathy (rAION), was used to determine AION-associated mechanisms of RGC death and associated regional retinal changes. METHODS rAION was induced in male Wistar rats, and the retinas analyzed at various times aft...
A 62-year-old hypertensive male presented with acute nonarteritic ischemic optic neuropathy (NAION) with contiguous macular edema and subretinal fluid in the right eye. Presenting vision was 20/1000. The patient was treated with intravitreal bevacizumab 1.25 mg/0.05 ml. At 1 month follow-up, the macular edema and the optic nerve head edema completely resolved with a good visual improvement up t...
A retrospective analysis of clinical profiles of 20 patients with anterior and posterior ischemic optic neuropathy and diabetic papillopathy was used to evaluate optic neuropathy in diabetes. We found that vascular optic neuropathy in diabetic patients resulted from microangiopathy, macroangiopathy, and certain structural factors in the optic nerve head.
Since the launch in 1998 of the anti-impotence drug sildenafil (viagra), the American food and drug administration has identified 50 cases of drug-related blindness, the so-called nonarteritic anterior ischemic optic neuropathy. This, very serious, side effect frequently leads to sudden, mostly irreversible loss of vision, and there is no proven effective treatment to cure patients or to preven...
Purpose Optic nerve (ON) damage following nonarteritic anterior ischemic optic neuropathy (NAION) and its models is associated with neurodegenerative inflammation. Minocycline is a tetracycline derivative antibiotic believed to exert a neuroprotective effect by selective alteration and activation of the neuroinflammatory response. We evaluated minocycline's post-induction ability to modify earl...
