PURPOSE: To report results of extraocular muscle surgery for superior oblique @entity7205 when medical treatment fails. METHODS: A retrospective review of 14 consecutive @entity1 undergoing superior oblique tenectomy and inferior oblique myectomy between 1976 and 2008. RESULTS: The mean age of onset of symptoms was 35.4 +/- 12.6 years (range, 16-59.5), with a mean duration of oscillopsia of 5 +/- 4 years (range, 1.5-17) prior to surgery. Medical treatment was unsuccessful in all 14. Preoperatively, 2 had a small @entity15170 that was consistent with an ipsilateral fourth (trochlear) nerve @entity912 ; 12 had no manifest tropia. Postoperatively, all had complete elimination of oscillopsia, and 12 of 14 were free of @entity892 in the primary position at 6 meters and 1/3 meter. The only 2 with @entity892 in the primary position after surgery were the 2 with a manifest @entity15170 preoperatively. Of the remaining 12 @entity1 , 5 had a @entity15170 of the affected eye limited to downgaze after surgery (mean of 6.2(Delta) +/- 1.6(Delta)). Of the 5, 3 needed contralateral inferior rectus surgery, and 1 required prism for downgaze. The mean follow-up was 4.1 +/- 2.4 years (range, 0.5-10). At the final visit, none had oscillopsia or uncontrolled @entity892 , but 3 (21%) needed prisms. CONCLUSIONS: Superior oblique tenectomy and inferior oblique myectomy effectively eliminate oscillopsia associated with superior oblique @entity7205 but result in @entity892 in downgaze in approximately 36% of @entity1 , which may cause symptoms in @entity1 who require a bifocal for near work.
