Phenotypic and Etiological Characterization of Susac Syndrome

SUSAC's Syndrome (SS) is characterized by the clinical triad of encephalopathy, hearing loss, and retinal artery branch occlusions. Since the first description of SS in 1979, hundreds of patients with SS, mostly young women, have been reported. However, comprehensive epidemiological, clinical and etiological features of SS have never been specifically addressed so far.
