Hemodialysis as a Possible Risk Factor for Ischemic Optic Neuropathy: Case Report (.pdf)

"Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) is presumed to result from circulatory insufficiency within the optic nerve head. NAION has been reported in association with many conditions that may predispose to decrease its perfusion. The hemodynamic compromise such as the one generated in systemic hypotension, blood loss and anemia may produce optic nerve ischemia. Hypotensive episodes in the setting of chronic anemia without blood loss, as in chronic hemodialysis, may result in Ischemic Optic Neuropathy (ION).
