Superior oblique myokymia (SOM) is an uncommon disorder characterized by episodic monocular oscillopsia. In most cases of SOM no specific etiology is found but occasional cases have been associated with intracranial tumors and head trauma. Recent radiologic evidence suggests that microvascular compression of the fourth cranial nerve may be a pathogenetic mechanism of SOM. This presentation will review the clinical presentation and course of SOM, including video examples, and discuss treatment options.Commercial interest
