Abstract

Purpose: To evaluate effectiveness of muscle transplantation for large angle strabismus

Methods: Prospective study of 9 eyes with large horizontal strabismus, undergoing conventional recess-resect with transplantation of resected muscle segment (4mm MR or 6mm LR) onto disinserted recessed muscle was done. Postoperative deviation and motility were analyzed at 1,3 and 6 months.

Results: 9 eyes of 8 patients were analyzed. Among 4 esotropia eyes, deviation improved from 86.25 pd(SD 9.60) for distance and 87.5 pd(SD 7.5) for near to 23.5 pd (SD 20.1) for distance and 30 pd (SD 15.8) for near after 6 months. Among 5 exotropias, it improved from 74 pd(SD 19.84) distance and 71 pd (SD 24.5) near to 29 pd(SD 25.17) for both distance and near. No ocular motility limitation was noted.

Conclusion: True muscle transplantation in combination with conventional recess-resect, for large angle strabismus works by increasing effective muscle length for recession, without compromising ocular motility.
