Observation of superior rectus transposition with posterior intermuscular suture for abducent paralytic strabismus

Objective To observe the effective of superior rectus transposition with posterior rectus transposition with posterior intermuscular suture for treatment of abducent paralytic strabismus. Methods A retrospection study. Totally 21 cases (21 eyes) of severe esotropia caused by abducent paralysis were treated by superior rectus transposition with posterior intermuscular suture. The cases were collected from April 2014 to December 2015 in our hospital. The position of eye in preoperation, during operation and postoperation were analyzed. Results Treated by superior rectus transposition with posterior intermuscular suture and medial rectus recession, during operation, superior rectus transposition corrected internal oblique 12±3.2o, posterior intermuscular suture of superior rectus and external rectus corrected internal oblique 4.2±1.6o, medial rectus recession 6-8mm, corrected internal oblique 14±4.2o. Esotropia of 21 cases were corrected significantly. Apparent improvement was obtained in paralytic eye. No significant vertical and rotational strabismus was induced. After 6 months to 2 years follow-up, the eye position kept stable and no obvious change occurred. Conclusions Superior rectus transposition with posterior intermuscular suture in treating abducent paralytic strabismus is feasible and its outcome is stable.
