Novel surgical approach to superior oblique myokymia

Abstract

Superior oblique myokymia (SOM) is a rare eye movement disorder that produces debilitating oscillopsia and diplopia. Various medical and surgical techniques have been reported to attempt to alleviate oscillopsia including superior oblique (SO) tenectomy with inferior oblique (IO) myectomy, SO nasal tendon displacement, and intracranial neurovascular decompression. These techniques have inherent risks of iatrogenic vertical strabismus or carry high risk for morbidity. We report a novel surgical approach that alleviates oscillopsia and avoids creating vertical strabismus.
