| Abstract |
|
This study was designed to assess the postoperative status of the large-recessed superior rectus muscle using hang-loose technique(HLT) in rabbits. We also examined the histopathological featores of the muscles in HLT recession. The results were as follows: In HLT recession, anterior displacement of the muscles was noted in 16 of 20 eyes(80%) and the degree of anterior displacement increased in time to three months postoperatively. The average degree of displacement in 20 eyes was 1.1mm. The anterior margin of the muscle was parallel with limbus in 12 of 20 eyes(60%). In HLT recession, inflammation and foreign body reaction in the muscle decreased while fibrosis increased with time. Two weeks after HLT recession, adhesion between the muscle and the sclera was observed. Therefore, the authors thought that these findings should be considered in the clinical use of hang-loose technique. |
