Abstract

In ischemic optic neuropathies, ischemia is due to deranged blood flow in the optic nerve. To understand their pathogenesis and management a firm grasp of the following is crucial: (i) the blood supply of the optic nerve (as discussed before – see Chap. 3), and (ii) the factors that influence the blood flow of the optic nerve head (ONH). It is the lack of in-depth knowledge of these two factors which is responsible for most of the controversy and confusion on ischemic optic neuropathies. The purpose of this chapter is an attempt to present a brief overview of the current state of our knowledge about the factors that finally determine the state of the circulation in the ONH, as discussed previously [1,2].
