Secondary glaucoma following carotid cavernous fistula
Carotid-cavernous fistulas are a major cause of secondary glaucoma due to increased episcleral venous pressure. We present the case of a 72-year-old female patient, treated at the Hospital de Clínicas at the Universidade Federal do Triângulo Mineiro (HC-UFTM), with pain, proptosis, episcleral engorgement, chemosis and pulsation in the right eye, with increased intraocular pressure (IOP) on anti-glaucomatous medication. Arteriography showed dural fistula to the right cavernous sinus, with reflux to orbital veins. Treatment with liquid embolization agent was performed, following full recovery of proptosis and congestion of the episcleral vessels. However, the patient maintained increased IOP because of narrow-angle glaucoma development due to the presence of goniosynechiae in 270°, which was controlled satisfactorily with medication.
