Abstract
AbstractAcute optic neuropathy due to a vascular cause is essentially a syndrome of ischemic optic neuropathy. The mechanism of ischemic optic neuropathy involves a fall in perfusion pressure to the optic nerve which, in susceptible individuals, leads to infarction of the prelaminar or retrolaminar portion of the optic nerve. Ischemic optic neuropathy can be subdivided into anterior ischemic optic neuropathy and posterior ischemic optic neuropathy . A special category is post‐operative ischemic optic neuropathy. This lecture will discuss the clinical features that distinguish these forms of ischemic optic neuropathy , the risk factors associated with them and the approach to their management.
