Superior oblique myectomy and trochlectomy in recurrent superior oblique myokymia.

Abstract

In patients operated on for superior oblique myokymia with superior oblique tenotomy or tenectomy, symptoms of oscillopsia recur in approximately one-half. Failure of treatment may be caused by incomplete transection of the tendon or by residual attachments and postoperative adhesions between the proximal segment of superior oblique tendon and the globe which allow superior oblique muscle contractions to be partially transmitted to the globe. We report a patient with recurrent symptoms of superior oblique myokymia following superior oblique tenectomy who was successfully managed with superior oblique myectomy and trochlectomy via an anterior orbital approach.
