Objective: To evaluate the clinical characteristics of protruding eyes and some other orbital lesions on patients with carotid-cavernous fistula. Subjects: 59 patients (62 bulging eyes) with carotid-cavemous fistula has been diagnosed and treated by embolization. Methods: Cross-sectional descriptive study at different time points: Before treatment, just after treatment and six months after the treatment, compared with the results on untreated patients.

Vision, vision field, intraocular pressure, papilledema, oculomotor paralysis... were progressed more slowly. Statistics in 6 months time have the following results: Protruding eyes were 3.2 percent, conjunctivitis - 4.8 percent, high intraocular pressure - 11.3 percent, optic disc atrophy 8. 1 percent, concave optic disc - 35.5 percent, oculomotor paralysis... Compared with clinical findings in the eye before embolization of some domestic and international researches, it shows that after embolization, the clinical recovery is significant. Patients with carotid-cavernous fistula should be treated early.
