Experimental suture studies in strabismus surgery. I. Reattachment rate of extraocular muscles after recession and resection operations.

We described a method for measuring the in vivo tensile strength of the muscle-scleral junction in rabbits. Data obtained on the reattachment time of extraocular muscles after recession and resection operations indicate the rate of healing is similar for both operations. Adequate wound healing is present by the 5th day after surgery, and sutures are probably unnecessary after 8 to 9 days. An ideal suture for strabismus surgery would be one that retains its strength during the first 8 to 9 days following surgery, then undergoes rapid absorption.

Experimental suture studies in strabismus surgery. II. Comparison of tensile strength of plain catgut with polyglycolic acid (Dexon) sutures after extraocular muscle surgery.

From our experimental studies it appears Dexon satisfies more of the criteria for an ideal suture for strabismus surgery than plain catgut for the following reasons. Its handling, tying, and knot-holding (if tighthened firmly) qualities are excellent. Tissue reaction is minimal. It seems to be non-antigenic. Of paramount importance. Dexon's tensile strength is high initially and it retains its strength through the critical period of muscle-scleral wound healing, then dissolves in a rapid uniform manner.
