Abstract

The present case study highlights about Central retinal vein occlusion secondary to carotid-cavernous sinus fistula. Carotid cavernous fistulas are a rare entity occurring as result of head trauma and also spontaneously. A 61 year-old man consulted for acute unilateral visual loss preceded by a five days history of red eye and a bruit of the head. The patient had a history of blunt head trauma with no associated systemic illness. Carotid-cavernous fistulas arise from abnormal connections between the carotid arteries and the cavernous sinus leading arterialized blood to shunt into the venous system leading to venous hypertension.
