Abstract

Superior oblique myokymia (SOM) is an uncommon condition of unclear etiology that results in episodes of oscillopsia and diplopia. There is no established treatment protocol for SOM. We present 2 cases of SOM successfully managed with topical levobunolol 0.5%; both patients responded to a short course of medication administration and required minimal ongoing therapy. Case 1 was a 69-year-old woman with left SOM who had previously undergone a left Harada-Ito procedure. Her SOM improved immediately on administration of levobunolol and was maintained at follow-up 1 year later. Case 2 was a 49-year-old man with right SOM that affected his ability to work. After 2 days of topical levobunolol 0.5% nightly in the right eye, SOM episodes ceased; he continues to use drops intermittently for occasional recurrences.
