PURPOSE
The purpose of this study is to compare the postoperative results of surgery for 60 patients with intermittent exotropia (20-30PD). METHODS: They were classified into two groups: one group with bilateral lateral rectus recession (n=34) and another group with unilateral medial rectus resection and lateral rectus recession (n=26). We assessed the postoperative results by comparing the deviation at postoperative 1 year to those at 1day, 1week, 1month, and 6months after surgery. RESULTS: The stisfactory result defined as orthophoria and deviation between 10PD esodeviation and 10PD exodeviation. The postoperative success rates are as follows: 65% in the bilateral rectus recession group and 62% in the unilateral lateral rectus muscle recession and medial rectus resection group. In the bilateral lateral rectus recession group, postoperative 1 day alignment of 11-15PD esodeviation showed the success rate of 83%. In the unilateral medial rectus resection and lateral rectus recession group, postoperative 1 day alignment of 1-5PD esodeviation resulted in the success rate of 80%. CONCLUSIONS: The initial postoperative esodevation of 11-15PD in bilateral lateral rectus recession and esodeviation of 1-5PD in unilateral medial rectus resection and lateral rectus recession can lead to good results. Postoperative 1 year surgical results for exotropia of moderate degree could be predicted from angle of deviation at postoperative 6 months, regardless of the type of surgery. |
