Sudden-Onset Blindness from a Spontaneous Carotid-Cavernous Fistula with Secondary Central Retinal Artery Occlusion

Abstract

High-flow carotid-cavernous fistulas (CCFs) typically present with blurry vision, headache, diplopia and pain with trauma1, however a ruptured cavernous carotid artery aneurysm may present similarly.2 We describe a case of spontaneous high-flow CCF presenting as sudden vision loss, with venous congestion and concomitant central retinal artery occlusion
