Abstract

Adjustable strabismus surgery sometimes fails because of changes in the angle of deviation which develops a few days after surgery. Therefore, the delayed adjustment was recommended; however, the postoperative tissue adhesion disturbed this delayed adjustment. We studied 20 eyes of 10 rabbits; adjustable strabismus surgery was performed on each of the right lateral rectus muscles by hemichangback technique for control study and the surgery on each left lateral rectus muscle was performed by same methods using polyethylene film. The polyethylene film was wrapped around the muscle allowing it to be placed between the muscle and sclera, and between the muscle and cojunctiva. The mean duration of postoperative tissue adhesion was 1.6 +/- 0.70 days in control group and 18.7 +/- 7.09 days in polyethylene group. These results suggested that the use of polyethylene film provides a valuable resource to defer the adjustment by preventing the postoperative tissue adhesion.
