Risk of Nonarteritic Anterior Ischemic Optic Neuropathy in Patients Prescribed Semaglutide.

JAMA ophthalmology
Importance Anecdotal experience raised the possibility that semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1 RA) with rapidly increasing use, is associated with nonarteritic anterior ischemic optic neuropathy (NAION).

Ischemic Optic Neuropathy

Neurologic Clinics, 1991
ION typically affects the older population with a sudden decrease in vision, altitudinal visual field loss, and a swollen optic nervehead. Systemic hypertension and diabetes mellitus are the most commonly associated medical problems. Occlusion of the posterior ciliary arterial blood supply to the retrolaminar optic nerve leads to axoplasmic stasis and ...

Migrainous ischemic optic neuropathy

Neurology, 1985
Anterior ischemic optic neuropathy (AION) is a stroke syndrome of the eye seen in isolation or as a manifestation of underlying disease. A case of migrainous AION is reported, and the implications of anterior visual pathway migraine discussed.

Anterior Ischemic Optic Neuropathy

Archives of Neurology, 1981
Though anterior ischemic optic neuropathy (AION) has been widely reported, it is not fully appreciated as one of the commonest causes of impaired vision in persons past middle age. These patients are not infrequently suspected of having an intracranial tumor.

Three Tesla 3D High-Resolution Vessel Wall MRI of the Orbit may Differentiate Arteritic From Nonarteritic Anterior Ischemic Optic Neuropathy.

Investigative Radiology, 2019
BACKGROUND Anterior ischemic optic neuropathy (AION) is the most common cause of acute optic neuropathy in older patients. Distinguishing between arteritic AION (A-AION) and nonarteritic (NA-AION) is paramount for improved patient management.

Unraveling the Enigma of Nonarteritic Anterior Ischemic Optic Neuropathy.

Journal of neuro-ophthalmology, 2019
Non-arteritic anterior ischemic optic neuropathy (NAON) is the second most common optic neuropathy in adults. Despite extensive study, the etiology of NAION is not definitively known.

Acute Ischemic Optic Neuropathy

JAMA: The Journal of the American Medical Association, 1985
Acute anterior ischemic optic neuropathy (AION) is a common cause of profound visual loss in the elderly and the not-so-elderly and is often associated with systemic disorders. Even so, this condition is not frequently discussed in the medical literature outside ophthalmology specialty journals.

Posterior Ischemic Optic Neuropathy

Ophthalmologica, 1981
3 patients (5 eyes) with posterior ischemic optic neuropathy (PION) are presented. PION is a distinct clinical entity, caused by ischemia of the posterior part of the optic nerve. These eyes presented with a visual acuity varying from normal to no light perception, optic nerve-related visual field defects, and no fundus abnormality (on ophthalmoscopy ...

Optical coherence tomography angiography features of optic nerve head drusen and nonarteritic anterior ischemic optic neuropathy.

Canadian Journal of Ophthalmology-journal Canadien D Ophtalmologie, 2019
OBJECTIVE To evaluate the optic disc microvasculature in optic nerve head drusen (ONHD) vasculature in comparison to acute nonarteritic anterior ischemic optic neuropathy (NAION) and normal eyes using optical coherence tomography angiography (OCT-A ...
