Sunglasses as an alternative alleviating agent for secondary Meige’s syndrome: Electrophysiological evidence

Abstract

Abstract Blepharospasm may be the most disabling of symptoms in Meige’s syndrome, and sunglasses or specialized tinted lenses (FL-41) have been suggested to be useful. The present report provides electrophysiological evidence to substantiate the utility of sunglasses as an alternative alleviating agent for Meige’s syndrome secondary to deep cerebral venous thrombosis with improvement extending beyond blepharospasm.
