A case of a patient with a zygoma fracture in combination with a carotid-cavernous sinus fistula--an arterio-venous fistula between the internal carotid artery and the cavernous sinus--is presented. The most frequent cause is trauma, but the carotid-cavernous sinus fistula itself may have been the cause of trauma. The patient showed complete loss of ocular motility and total monocular blindness. Treatment of the fistula with endoarterial coil embolization was followed by improvement of vision and ocular motility, until finally complete recovery of ocular functions, which is exceptional. In this case, careful analysis of the MRA's showed that the CCSF most likely developed in the posttraumatic phase.
