Abstract

We compared the clinical results of 37 patients who had undergone bilateral lateral rectus muscle suspension recession and conventional recession from July, 1989 to Decem ber, 1991 at St. Mary's Hospital, Catholic University Medical College. The results were as follows; 1. Mean preoperative deviation, mean recession amount, and mean postoperative deviation were 40PD, 6.9mm and 8PD respectively in suspension recession group and 36PD, 6.3mm, and 4PD respectively in conventional recession group. 2. Success rate was 67% in suspension recession and 86% in conventional recession at 6 weeks postoperatively, and 60% and 82% respectively at the time of most recent follow-up. The statistical difference in the success rate between suspension and conventional recession group was not found. 3. Undercorrection were 33% in suspension recession and 14% in conventional recessoin at 6 weeks postoperatively, and 40% and 18% respectively at the time of most recent follow-up. It appears that high number of undercorrections occurred in suspension recession. But statistical difference in undercorrection between suspension and conventional recession was not found. 4. Overcorrection was not found in suspension recession and conventional recession group at 6 weeks postoperatively and the time of most recent follow-up.
