A 63-year-old male with a healthy history presented with a red and swollen right eye for 3 months. Neuro-ophthalmic examination showed slight bulging of the right eyeball, and multiple spiral conjunctival vessels were visible on the surface of the right conjunctiva, suggesting a right carotid cavernous fistula. Cerebral angiography showed left occipital dural arteriovenous fistulas. After endovascular embolization treatment, the patient's abnormal craniocerebral venous drainage and right eye syndrome resolved, and there was no recurrence during the one-month clinical follow-up after surgery.
