Adhesion Power and Histopathologic Findings After Muscle-scleral Tuck of Extraocular Muscles with Absorbable Suture Material in Rabbits

ABSTRACT

It was reported that muscle-scleral tuck with nonabsorbable suture material helps to preserve anterior ciliary artery circulation and to prevEnt anterior segment ischemia. The authors measured maximum adhesion power and obsesved histopathologic findings at 1st, 2nd, 4th, and 8th week following a muscle-scleral tuck procedure with absorbable suture material in rabbits. Maximum adhesion powers were increasing with time, 110, 120, 150, and 250gm at each week respectively, and kept enough tension for using absorbable suture material Histopathologic findings demonstrated that inflammatory and foreign body reactions decreased with time, and collagen fibers were proliferated at muscle scleral contact area, and fibers in muscle and sclera connected each other and formed firm adhesion. We concluded that muscle-scleral tuck with absorbable suture material maintained adhesion power enough as a rectus muscle strengthening procedure.
