Unilateral Isolated Paucisymptomatic Optic Disc Edema

Unilateral isolated optic disc edema (UIODE) represents a challenging clinical presentation that frequently precipitates an extensive diagnostic work-up. Patients without an apparent diagnosis despite appropriate investigations are often categorized as having 'papillophlebitis,' an entity that is poorly defined in the existing literature.
