|
Purpose:To compare the surgical outcomes between bilateral lateral rectus muscles (BLR) re-recession and bilateral medial rectus muscles (BMR) resection in recurrent exotropia.
Methods: The medical records of patients with recurrent exotropia who underwent surgery for intermittent exotropia during the 6 years from January 2001 to December 2006 and followed up for more than 6 months were reviewed retrospectively.
Results: In group A, BLR recessions was performed at the first surgery and BLR re-recession was performed at the second surgery. In group B, BLR recession was performed at the first surgery and BMR resection at the second surgery. Success rates at the last follow-up after the second operation were 81.9% in Group A and 83.3% in Group B, showing no statical difference between the two groups. In group A, no significant underaction of the BLR was noted. Success rates were not statistically different between the 2 mm re-recessed subgroup and 3 mm re-recessed subgroup.
Conclusion: The results support the notion that BLR re-recession successfully corrects recurrent exotropia without producing significant limitation of abduction.
