Abstract

Intermittent exotropia shows higher incidence in Oriental than in Caucassian. The results of surgical treatment is variable and the factors related to that have been a matter of some dispute. The authors retrospectively reviewed the relationships between the factors and the results of surgical treatment on the 186 children who had intermittent exot ropia and who were treated with bilateral lateral recti recessions. The 162 cases(86.5%) of 187 cases showed satisfactory surgical results, which was less than 5 prism diopters of exotropia and esotropia at far and near, with good stereopsis. The age at onset and initial surgery, the time interval from onset to initial surgery, the preoperative deviation angle, the types of intermittent exotropia, the inferior oblique overaction and dissociated vertical deviation did not significantly influence the surgical results(p>0.05). But, early postoperative overcorrection of 6~9 prism diopters lead to successful result(95.6%). This study revealed initial postoperative overcorrection influence the surgical results of bilateral lateral recti recessions in intermittent exotropia(p=0.03).
