INTRODUCTION Here, we describe a patient who presented with anterior ischemic optic neuropathy (AION) and subsequently developed uveitis. CASE A 69-year-old man was referred to our hospital and initially presented with best-corrected visual acuities (BCVA) of 20/40 (right eye) and 20/1000 (left eye) and relative afferent pupillary defect. Slit-lamp examination revealed no signs of ocular infl...

The purpose of this case report is to evaluate the visual outcome of an intravitreal triamcinolone acetonide injection (IVTA) as a treatment for a patient with acute nonarteritic anterior ischemic optic neuropathy (NAION). A 65-year-old male patient with severe visual loss due to acute NAION was treated with 4 mg/0.1 mL IVTA. Fundus examination and measurements of the patient's best-corrected v...

Purpose. To describe a patient who developed bilateral, simultaneous nonarteritic anterior ischemic optic neuropathy (NAION) after ingestion of Sildenafil citrate (Viagra) for erectile dysfunction. Methods. Observational case report. Results. A 60-year-old diabetic man noted sudden decrease of vision in both eyes 16 hours after his third consecutive 50 mg daily Sildenafil ingestion. A diagnosis...

Background: To report the sequential peripapillary vascular changes in nonarteritic anterior ischemic optic neuropathy (NAION) with optical coherence tomography angiography (OCTA) Methods: A 60-year-old male presented with right eye painless vision loss leading to inferior field defects and right eye 0.5 vision. The sequential OCTA was performed at presentation and 5 months later to evaluate th...

PURPOSE To report a case of severe conjunctival-corneal melt in association with carotid artery stenosis. METHODS Observational case report. RESULTS A 76-year-old man with a history of bilateral severe carotid artery occlusion and nonarteritic ischemic optic neuropathy developed a spontaneous bulbar conjunctival defect. Despite intensive lubrication, and attempts at surgical closure includi...

Purpose. To compare optic disc topography performed by confocal laser ophthalmoscopy in eyes with nonarteritic anterior ischemic optic neuropathy (NAION), arteritic anterior ischemic optic neuropathy (AAION), and open-angle glaucoma (OAG), adjusting for the amount of retinal ganglion cell (RGC) loss, as measured by nerve fiber layer (NFL) thickness and average visual field loss. Methods. At fou...

Anterior ischemic optic neuropathy is caused by microvascular occlusion of the prelaminar or laminar portion of the optic nerve head. The main types are arteritic, non-arteritic, and autoimmune. Few cases were reported following coronary artery bypass surgery. A 63-year-old man, who is both diabetic and hypertensive, underwent coronary artery bypass graft complicated postoperatively by sudden v...

INTRODUCTION Pseudo-Foster Kennedy syndrome is a triad consisting of ipsilateral optic atrophy, contralateral optic disc edema, and ipsilateral anosmia in the absence of an intracranial mass. Vitamin B12 plays an important role in DNA synthesis, and its deficiency causes peripheral neuropathy, myeloneuropathy, and, very rarely, optic neuropathy. CASE PRESENTATION In this study, we describe a ...

In several diseases, fractal analysis has been proven useful to give contribution in diagnosis and prognosis of the patient and to improve treatments. In the present work we have evaluated the mass dimension of the vascular pattern of optic nerve head in non-glaucomatous optic neuropathic patients and healthy controls. Static fluorescein angiogram was performed and the images of the early venou...
