Optic nerve infarction

A specific type of optic disc damage and visual field loss has been emphasized. The changes occur acutely at the inferotemporal disc margin and do not seem to progress. Such patients have normal intraocular pressures. We have termed this entity "acute inferotemporal prelaminar optic disc infarction syndrome" in an effort to avoid using the word glaucoma. Although similar events can occur in glaucomatous eyes, we feel that such changes are not progressive and that sophisticated diagnostic studies should be avoided. Three cases are presented as examples.
