Abstract

We analyzed the clinical results of 58 patients who had undergone bilateral medial rectus muscle recession from January, 1988 to June, 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 51PD, 5.8mm and 4PD respectively in suspension recession group and 53PD, 5.7mm and 4PD respectively in conventional recession group. 2. Overall success rate was 81% in suspension recession and 84% in conventional recession at 6 weeks postoperatively, and 67% and 76% respectively at the time of most recent follow-up. The statistical difference in the success rate of recession over 6.0mm and recession under 5.5mm as well as overall success rate between suspension and conventional recession group was not found. 3. Overcorrection was 5% in suspension recession and 2% in conventional recession at 6 weeks postoperatively, and 14% and 3% respectively at the time of most recent follow-up. 4. Undercorrection were 14% in suspension recession and 14% in conventional recession at 6weeks postoperatively, and 19% and 21% respectively at the time of most recent follow-up.
