Abstract

PURPOSE: The purpose of this study was to compare the surgical results between unilateral lateral rectus recession-medial rectus resection (R and R) and bilateral medial rectus resections in recurrent exotropia.
METHODS
In this retrospective study, 22 patients with recurrent exotropia of the basic or pseudodivergence excess types were enrolled. In group A (14 patients), unilateral R and R was performed during the first operation, and R and R was performed in contralateral eyes during the second operation. In group B (8 patients), bilateral lateral rectus recessions were performed during the first operation and bilateral medial rectus resections during the second operation.
RESULTS
The mean time interval between the first and second operations was 28.9 months (range, 5 to 64 months) in Group A and 59.9 months (range, 35 to 75 months) in Group B, which was a significant difference between the two groups (p=0.006). The success rates at last follow-up after the second operation were 85.7% in Group A and 87.5% in Group B, which was not statistically different between the two groups (p<1.000).
CONCLUSIONS
There was no difference in success rate after the second operation between the two groups. Therefore, the operation method for recurrent exotropia can be chosen according to the operator's preference.
