- Abstract: Recently hang-back recession is chosen instead of conventional recession to get better result in strabismus surgery. Jampolsky method, a popular method of hang-back recession, has some draw-backs; the extraocular muscle width can be decreased, the center of the muscle can be sagging posteriorly, and the amount of recession can be somewhat shortened than expected in operation. Accordingly, we devised a new modified hang-back recession and compared with Jampolsky method. Two months after respective operation in 7 albino rabbits, the width of the muscle comparing to preoperative condition, the amount of recession, and the sagging of middle part of the muscle were evalvated in comparison with the preoperative findings. The width of muscles was significantly shortened in Jampolsky method in comparison with preoperative condition (p<0.05), but not in our new method (p>0.05). The amount of recession by Jampolsky method was significantly shortened than expected in operation (p<0.05), but not by our new method (p>0.10). The significant sagging of the muscle was found with Jampolsky method (p<0.05), but not with our modified method (p>O.lO). In review of these findings, our new method is devoid of some draw backs of Jampolsky method.
