Clinical InformationClinical
Optic Neuropathy, Ischemic
ischemic injury to the optic nerve which usually affects the optic disk (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). the injury results from occlusion of arterial blood supply which may result from temporal arteritis; atherosclerosis; collagen diseases; embolism; diabetes mellitus; and other conditions. the disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. the optic disk appears normal in posterior ischemic optic neuropathy. (glaser, neuro-ophthalmology, 2nd ed, p135)
Patient EducationClinical
Optic Nerve Disorders
The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs. It may affect one or both eyes.
