Intravitreal Triamcinolone in Susac Syndrome.

PURPOSE To report the use of intravitreal triamcinolone for Susac Syndrome in one patient. METHODS Case report. RESULTS A 23-year-old woman presented with presented with sudden visual loss in the left eye with associated neurologic symptoms. Ophthalmic examination and fluorescein angiography showed multiple areas of branch retinal artery occlusion, bilaterally. Magnetic resonance imaging showed dot-like, diffusion-restricted lesions in the corpus callosum, and audiometry showed low-frequency sensory hearing loss, compatible with Susac Syndrome. The patient received a single intravitreal injection of triamcinolone (4 mg) in the left eye. One week later, before beginning systemic corticosteroids, all signs and symptoms resolved in the left eye only. CONCLUSION In cases of delayed systemic corticosteroid therapy, intravitreal triamcinolone resolves the ocular manifestations of Susac Syndrome.
