Two cases of orbital varicosities without extraorbital extension are presented. Radiographic evidence of the varices was obtained in both cases. One varix was demonstrated by orbital venography while in the other, orbital phleboliths were conspicuous in the plain film. In one case the varix was clinically evident at birth while the other became evident only in the third decade. Both cases had the clinical sign of intermittent exophthalmos. No surgery was attempted in the patients. A review of cases of intermittent exophthalmos in the literature revealed a variety of lesions, including localized orbital varices, orbital varices with intracranial extension, and arteriovenous malformations.
