Ischemic Optic Neuropathy Associated With Internal Carotid Artery Dissection

Ischemic optic neuropathy associated with internal carotid artery dissection.

BACKGROUND Ischemic optic neuropathy (ION) is an infarction of the anterior or, less frequently, posterior part of the optic nerve, usually due to a disease of small arteries supplying the optic nerve. Carotid stenosis or occlusions are rare causes, and among them, carotid dissections have been so far reported in only 5 cases. METHODS We describe 4 patients with ION (2 anterior and 2 posterio...

Optic Neuropathy Mimicking Normal Tension Glaucoma Associated with Internal Carotid Artery Hypoplasia

Anterior ischemic optic neuropathy is not associated with carotid artery atherosclerosis.

BACKGROUND AND PURPOSE The relation between anterior ischemic optic neuropathy and carotid artery atherosclerotic disease is unclear. We studied patients with anterior ischemic optic neuropathy to determine if they had an increased occurrence of carotid artery stenosis. METHODS Fifteen consecutive patients with anterior ischemic optic neuropathy were evaluated prospectively for cervical carot...

Anterior ischemic optic neuropathy following neck dissection.

BACKGROUND Ischemic optic neuropathy (ION) is a rare but devastating complication of surgery. It has traditionally been associated with intraoperative hypotension in patients with underlying arteriosclerosis. METHODS We present a case of ION following bilateral neck dissections in which there was minimal intraoperative hypotension and preservation of both internal jugular veins. The potential...

Anterior Ischemic Optic Neuropathy Associated with Udenafil

We report a case of anterior ischemic optic neuropathy associated with udenafil. A 54-year-old male presented with an acute onset visual field defect of the right eye after udenafil use. Examination revealed a relative afferent pupillary defect and a swollen disc. Automated visual fields revealed an enlarged blind spot and a narrowed visual field. Fluorescein angiography revealed both an inferi...
