Abstract

Authors retrospectively analyzed 22 cases of inferior oblique overaction, which were treated by means of infetior tlblique recession from May 1983 to June 1985. We compared preoperative and postoperative hyperdeviation in the primary position and adduction, and calculated the amount of corrected hyperdeviations in the prirrtary position and adduction pet millimeter of inferior oblique recession. The results were as follows: 1. The overall success rate was 84.4 % in primary inferior oblique overaction. 2. The amounts of correction in the primary position per millimeter of inferior oblique recession were 0.69 prism diopter. 3. The amounts of correction in adduction per millimeter of inferior oblique recession were 1.94 prism diopter. 4. Decrement amounts in adduction compared to in the primary position were 1.59 prism diopter per millimeter of inferior oblique recession.
