Abstract
The purpose of this study was to evaluate the effects of surgery on binocular function in intermittent exotropia who had subnormal preoperative stereoacuity of more than 100 seconds of arc with Titmus test in 30 patients, from January 1995 to June 1997. Sixteen were male and 14 were female. Age was 10.8[4~40] years old in average, and postoperative follow up period was 20.8[6~36] months in average. We evaluated visual acuity, refractive error, angle of exodeviation, fusional status with Worth-4-Dot test and stereoacuity with Titmus test before and after surgery. The success rate was 70%[21 of 30 patients] with equal to or less than 10 prism diopters. There was no overcorrection after surgery. There was an improvement of stereoacuity in 28 out of 30 patients[93%] after surgery. Among 28 patients, 19 patients[68%] had normal stereoacuity equal to or less than 100 seconds of arc. The fusion was improved in 20 out of 30 patients[67%]. We also evaluated the stereoacuity and fusional status in patients with postoperative deviation over 10 prism diopters. Stereoacuity was improved in all 9 cases. Fusion was improved in 4 cases. In conclusion, we can expect an improvement in stereoacuity and fusional status with surgery in intermittent exotropia, even though postoperative realignment of deviation was not achieved within 10 prism diopters.
