Fluorescein Angiography as a Surrogate Marker of Disease Activity in Susac Syndrome.

Objectives: To evaluate the sensitivity of fluorescein angiography (FA) in detecting disease activity in Susac syndrome.

Methods: We conducted a blinded analysis of all FA, brain MRI, and audiogram examinations performed throughout the follow-up of patients with Susac syndrome.

Results: A total of 79 FA examinations, 85 brain MRI scans, and 49 audiograms were analyzed from 9 patients followed for a mean (SD) period of 6 (4) years.
