Non-arteritic Anterior Ischemic Optic Neuropathy (NAION)
2014A 65-year-old male presented with acute, painless vision loss in the lower portion of his left eye (OS) for one day. Past medical history was significant for hypertension, hyperlipidemia, and coronary artery disease with previous coronary artery stenting. Significant medications included aspirin and clopidogrel (Plavix).

OCT angiography of acute non-arteritic anterior ischemic optic neuropathy
Journal Français d'Ophtalmologie, 2017To describe changes of the retinal peripapillary microvasculature on optical coherence tomography angiography (OCT-A) in non-arteritic anterior ischemic optic (NAION) neuropathy.Observational study of 10 patients at the acute phase of NAION. OCT-A was performed using a 3mm×3mm square centered on the optic disc (Cirrus HD-OCT with Angioplex, Carl Zeiss ...

Treatment of Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION)
2019Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common acute optic neuropathy in older individuals and usually occurs in patients with vascular risk factors and a “disc at risk” (i.e., a small optic nerve head and an absent or small physiologic cup).

Mitochondrial DNA nucleotide changes in non-arteritic ischemic optic neuropathy
Neurology, 2004The authors sequenced the entire mitochondrial DNA coding region in a group of 19 patients with non-arteritic anterior ischemic optic neuropathy (NAION) and in 100 controls. Synonymous and nonsynonymous nucleotide changes were more common in NAION patients (p < 0.001).

Non-arteritic anterior ischemic optic neuropathy and refraction.
Bulletin de la Societe belge d'ophtalmologie, 1997A small cup-disk ratio has been reported as a risk factor in non-arteritic anterior ischemic optic neuropathy. Hyperopia is possibly related with a small cup-disk ratio. The purpose of the present study is to compare the refraction of 37 eyes with non-arteritic anterior ischemic optic neuropathy with a sex and age matched control group of 74 eyes.

Non-arteritic anterior ischemic optic neuropathy with retinal emboli
Neuro-Ophthalmology, 2001We report a case of non-arteritic anterior ischemic optic neuropathy (NAION) associated with retinal emboli in a 68-year-old man with decreased vision. Carotid Doppler imaging revealed critical stenosis (80–99%) of the ipsilateral internal carotid artery. Carotid endarterectomy was performed and two weeks postoperatively a partial improvement in visual

Non-arteritic Anterior Ischemic Optic Neuropathy (NAION)
2018A 65-year-old male patient entered a local hospital with visual complaints of a black shadow in his temporal field OD, which rapidly grew larger in the subsequent 3 days. He was given prednisolone 4# bid for 10 days. However, there was no improvement after medication. He visited us for a second opinion concerning blurry vision in the right eye.

[Methotrexate in Atypical Non-Arteritic Ischemic Optic Neuropathy].
Klinische Monatsblatter fur Augenheilkunde, 2018Background: Optic nerve disease can occur from a variety of different causes, with vascular, inflammatory or toxic pathologies. In such cases, it is hardly possible to clarify the aetiology. These diseases of the optic nerve are usually accompanied by progressive loss of visual field and visual impairment.

Pathogenesis of Classical Non-arteritic Anterior Ischemic Optic Neuropathy
2011Non-arteritic anterior ischemic optic neuropathy (NA-AION) is the most common type of ischemic optic neuropathy. Although findings of sudden onset of segmental visual field defect, initially with optic disc edema with a few peripapillary hemorrhages and later on optic atrophy were reported in the very early literature, the pathogenesis and management ...
