Evaluation of an absorbable muscle sleeve to limit postoperative adhesions in strabismus surgery.

A muscle sleeve fashioned from polyglactin 910 Vicryl mesh was used in a rabbit animal model to evaluate its efficacy in decreasing postoperative adhesions encountered in extraocular muscle surgery. Clinical observations, as well as gross and histological comparison of the experimental and control groups, revealed a significant reduction in postoperative adhesions under conditions of normal surgical trauma. Where there was extensive trauma, however, no significant reduction was observed. No evidence of toxicity of the material to ocular tissues was found.
