A 22-year-old gentleman sought consult for noticing double vision, forward protrusion of the left eye with dull pain, and whooshing sound in his left ear for 15 days. He had suffered trauma to his right side of the face following a road traffic accident 2 months back. The computed tomography (CT) at the time of injury showed maxillofacial fractures on the right side, and his records suggested that they were managed conservatively. On examination, he showed the left-sided pulsatile axial proptosis, dilated episcleral vessels with bruit over the orbit and temporal fossa, diplopia, restricted elevation as well as abduction [Figure 1]. His BCVA was 6/9, N6, intraocular pressure was 22 mmHg with normal reacting pupil, and fundus in the left eye, while the right eye was unremarkable. CT angiography showed immediate enhancement of the left cavernous sinus with grossly dilated superior ophthalmic vein suggesting possibility of a carotico-cavernous fistula [Figure 2] without any bony fractures on the left side. Digital subtraction angiography was performed by a neurointerventional radiologist, which demonstrated a high flow-direct carotico-cavernous fistula (Type A) that was subsequently successfully treated with coil embolization procedure [Figure 3]. His symptoms resolved completely within 2 weeks of intervention [Figure 4].

| Discussion|| |
Craniofacial trauma is a major cause of CCF. When present, an early detection and treatment of CCF is essential to preserve visual acuity and avoid multiple cranial nerve palsies. Carotico-cavernous fistula contralateral to the side of maxillofacial injuries is rarely reported. Optimal treatment for direct CCF involves closure of abnormal arteriovenous communication and preservation of internal carotid artery patency. The techniques utilized by interventional radiologist include coil embolization, balloon occlusion of fistula, or covered stent grafts., A timely and successful occlusion of fistula can lead to resolution of proptosis, diplopia, and raised episcleral venous pressure. The role of an ophthalmologist in early detection of CCF is to be emphasized.
