Ischemic optic neuropathies.

ABSTRACT

Primary or secondary impairment of blood supply to the optic nerve results in a spectrum of ischemic optic neuropathies with multiple etiopathogenesis. Among these the clinical features of traumatic and radiation optic neuropathy are outlined. Diagnostic criteria, associated conditions, risk factors and functional prognosis of anterior ischemic optic neuropathy are reviewed and discussed in the light of the contribution of recent literature.
