Intractable glaucoma: Hunt for carotico-cavernous fistula

Abstract

Carotico-cavernous fistula is a dural arteriovenous fistula arising from abnormal arteriovenous shunting between the internal carotid artery and the cavernous sinus. Imaging features in a rare case presenting with intractable glaucoma due to bilateral carotico-cavernous fistula following head injury are reported in this article.
