AIM To determine if frequency doubling technology perimetry (FDT) is more sensitive to optic nerve injury in non-arteritic ischaemic optic neuropathy (NAION) than standard automated perimetry (SAP). METHODS Charts from 18 patients (20 eyes) with NAION with altitudinal defects who underwent a complete neuro-ophthalmic examination, SAP, and FDT were reviewed. The extent of damage as determined ...

PURPOSE To evaluate the macula with spectral domain type optic coherence tomography (OCT) in eyes with acute nonarteritic anterior ischemic optic neuropathy (NAION) at the presentation visit. METHODS Medical charts of the 133 patients who received the diagnosis of acute NAION between January 2008 and July 2014 at the Neuro-ophthalmology unit of Dokuz Eylul University were reviewed retrospecti...

background: sleep apnea is temporary cessation or absence of breathing during sleep. significant increase in blood pressure is clinically seen in apneic episodes. the aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (naion) in a case control study. methods: nineteen naion patients (9 men and 10 women) and 31 age and sex...

BACKGROUND Although cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is considered a cerebrovascular disorder with almost exclusively neurological symptoms, the arteriopathy is generalized and involves choroidal and retinal vasculature as demonstrated by fluorescein angiographic and ocular electrophysiological abnormalities. The occurrence of ...

purpose : to evaluate the correlations between visual field (vf) defects with retinal nerve fiber layer (rnfl) thickness in nonarteritic anterior ischemic optic neuropathy (naion) eyes, compare different gdx parameters with the other healthy contralateral eyes, and calculate receiver operating characteristic (roc) curve for the gdx parameters methods : eighteen patients with unilateral naion fr...

Seven patients, aged between 50 and 69 years, had typical features of nonarteritic anterior ischemic optic neuropathy (NAION) within 36 hours after ingestion of sildenafil citrate (Viagra) for erectile dysfunction. Six patients had vision loss within 24 hours after use of the agent. Final visual acuity in the affected eye ranged from 20/20 to light perception. Both eyes were affected in one ind...

Abstract Introduction Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) is an ischemic insult to the anterior portion of optic nerve with unclear etiology. Several small sized studies and case reports have demonstrated association between OSA NAION. In this case, we present a patient bilateral NAION who was later diagnosed which may signify important clinical association. Report case(s) A...
