Abstract:
We rerport a 69-year-old man who presented with diplopia. He had a conjunctival injection with corkscrew-vessels, proptosis, and sixth cranial nerve palsy in his right eye (RE), and was diagnosed with a right carotid-cavernous fistula (CCF). Intraocular pressure was within normal limits. Gonioscopic examination revealed a pinkish appearance of the trabecular meshwork, but the Schlemm's canal could not be identified on anterior segment optical coherence tomography (OCT). We discuss the potential usefulness and limitations of OCT in the assessment of the Schlemm's canal in CCF.
