The Surgical Effect of Posterior Fixation Suture in Incomitant Strabismus

Purpose: To know the surgical effect and the indication of posterior fixation suture in incomitant strabismus. Methods: From January 2003 to October 2004, posterior fixation sutures were used in five patients with strabismus after orbital wall fracture and in three patients with high AC/A accommodative esotropia. Using Worth 4-dot tests, we compared the amount of incomitant deviation before and after surgery. Results: The mean decrease in deviation after surgery was 7.8±2.6PD(P=0.04) in patients with strabismus after orbital wall fracture, and 11.3±4.2PD in those with high AC/A ratio accomodative esotropia. Conclusions: The posterior fixation suture was effective in reducing the amount of incomitant deviation occurring in cases of strabismus after orbital wall fracture and cases of high AC/A accommodative esotropia.
