Posterior Ischemic Optic Neuropathy
Ophthalmologica, 19813 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 ...

Ischemia of the optic nerve may occur in several forms, usually associated with vasculopathic risk factors or vasculitis, and may present with various patterns of optic disc appearance and dysfunction. Though a proven therapy is not available for the most common syndromes, correct identification may present severe visual loss or systemic complications ...

Anterior Ischemic Optic Neuropathy
Seminars in Ophthalmology, 1995AION is the most common acute optic neuropathy in patients over 50 and, although the diagnosis is often straightforward, our methods for managing the associated visual loss are inadequate. Analysis of the wealth of information gained from recent clinical studies may move us closer to an effective therapy.
