Abstract
Objective To analyse the long-term efficacy of strabotomy surgery for sensory exotropia. Methods Thirty-three cases of sensory exotropia from Jan. 2011 to Dec. 2015 who underwent monocular strabismus surgery were retrospectively analyzed. All cases were randomly divided into two groups: over corrected group postoperative, 5△-10△ esotropia after surgery, 15 cases, and orthophoria group postoperative, 18 cases. Results The follow-up time was 12-52 months. At last follow-up, orthophoria occurred in 26 cases(78.79%), under-corrected in 7 cases(21.21%), and none was over-corrected. The postoperative orthophoria rate of over corrected group was higher than that of orthophoria group. The difference was statistically significant (P 0.05). Conclusion Strabismus surgery for the treatment of sensory exotropia is a effective method with high satisfaction. The patients with immediate mild over correction after surgery have good postoperative eye position. The patients with preoperative smaller-angle strabismus have good postoperative eye position. BCVA of squinting eye has no effect on postoperative eye position. Key words: Exotropia, sensory; Strabismus surgery; Efficacy, long-term
