Evaluation of lateral incomitance in mid-term follow-up after different surgical methods for basic exotropia in children

Abstract

AIM: To study the correlation between the selection of surgical methods for children with basic exotropia and the incidence of lateral incomitance and correction effect.METHODS: Retrospective study. Clinical data of 180 children with basic exotropia who received treatment in the ophthalmology department of our hospital from June 2018 to December 2020 were selected. The patients were divided into 104 cases in monocular recess-resection group(R & R group)and 76 cases in binocular lateral rectus recession group(BLR-rec group)according to the surgical method. The general information, correction effect, the degree of surgical strabismus and the lateral incomitance were compared between the two groups.RESULTS: There were no differences in the degree of near and far strabismus between 2 groups at 3d, 1 and 6mo after surgery(all P>0.05). The correction rate of the R& R group at different time after surgery was higher than that of the BLR-rec group(P0.05).CONCLUSION: R & R is better than BLR-rec in correcting children's basic exotropia, and it can reduce the incidence of lateral incomitance.
