| Summary: |
Ischemic disorders of the
optic nerve constitute an important cause of visual loss.
Therefore, to understand the pathogenesis of these
diseases, it is imperative to be familiar with the
vascular anatomy and physiology of the optic nerve.
The purpose of this paper is to present a brief overview
of the current state of knowledge on this topic. The
blood supply of four anatomical regions of the optic
nerve, factors influencing the optic nerve circulation
and autoregulation mechanism are presented. |
