Exotropic shift is a significant problem in the exotropia.There has been much presumption about factors that affect the surgical outcome of intermittent exotropia such as amblyopia, stereopsis, age at operation, frequency of manifestation, deviation of angle and associated strabismus.The authors compared preoperative and postoperative factors between 36 patients who had second operation because of recurrent exotropia and 30 patients who had satisfactory surgical results.A 'satisfactory surgical result'was defined as a final alignment of orthotropia, esotropia less than 5 prism diopter or exotropia less than 10 prism diopter at postoperative 6 months.Sex, age at operation, angle of deviation, presence of amblyopia, associated hypertropia and type of intermittent exotropia were not different between two groups. Inferior oblique overaction and poor stereopsis were more common in reoperation group (p<0.05).Initial postoperative undercorrection in satisfactory surgical result was also more frequent in reoperation group (p<0.05).
