Abstract
Two cases of intermittent exophthalmos are reported. In both instances, cerebral angiography and orbital venography failed to outline the lesion, which was clearly demonstrated with the aid of computerized tomography. An orbital varix was seen to be the cause of proptosis in one surgically verified case, whereas in the other this same diagnosis was suspected on the basis of the clinicoradiological findings. The etiology, clinical manifestations, and management of orbital varix are briefly discussed.
