title: Presumed phlebitis of the optic disc.
abstract: The clinical picture of unilateral disc edema suggests the presence of ocular, orbital, or intracranial disease. This report focuses on a poorly appreciated and often overlooked cause of unilateral disc edema, presumed phlebitis of the optic disc, along with a review of the  literature. Typical case presentations are reviewed, and emphasis is placed on the neurophthalmologic approach to this entity. An appropriate diagnostic evaluation and indications for treatment are presented. Awareness of this syndrome can eliminate extensive neurodiagnostic procedures for the patient with a typical clinical picture.
