Onyx Embolization of Carotid-Cavernous Fistulas and Its Impact on Intraocular Pressure and Recurrence: A Case Series

BACKGROUND Carotid-cavernous fistulas (CCFs) are acquired pathological shunting lesions between the carotid artery and the cavernous sinus leading to elevated intraocular pressure (IOP). CCFs are commonly treated via endovascular embolization, which theoretically restores physiological pressure differentials. OBJECTIVE To present our institutional data with CCF treated with embolization and discuss endovascular routes, recurrence rates, and...
