[Incidence of non-arteritic anterior ischemic optic neuropathy in glaucomatous patients].

Abstract

Raised intraocualr pressure has been suggested to be a contributing factor in NAION occurrence. Thus, there should be a high NAION incidence rate in glaucoma patients when compared with that of the general population. From June 1990 to December 1991, we retrospectively surveyed 180 glaucoma patients to find the incidence of NAION, but no NAION cases were found. We concluded that the increase in intraocular pressure is not a major factor to cause NAION.
