Surgical Results of Modified Harada-Ito Operation for Excyclotorsion

ABSTRACT

PURPOSE: We evaluated the efficacy of the modified Harada-Ito operation for excyclotorsion in acquired superior oblique palsy patients after trauma. METHODS: This study represents a retrospective review of 10 eyes in 9 patients who were surgically treated for excyclotorsion. Cyclotorsion was measured with the double maddox-rod test and fundus photographies preoperatively and postoperatively. RESULTS: The median measured change in excyclotorsion before and after the surgery in the primary gaze was reduced from 15.67 +/- 6.00 to 4.78 +/- 3.42 according to fundus photographies and from 12.30 +/- 6.27 to 2.45 +/- 3.73 according to the double maddox-rod test. Subjective and objective changes in excyclotorsion werer not significantly different. CONCLUSIONS: The Modified Harada-Ito operation is an effective treatment for correcting excyclotorsion. Although not statistically significant, the amount of excyclotorsion on fundus photography is exaggerated. This point should be considered to achieve effective surgery.
