Background: Long-term surgical outcomes were compared between bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession combined with medial rectus resection in the same eye (R&R) for therapy of basic type intermittent exotropia (IXT) with equal dominance.
Methods: Eighty-six subjects(3–11 years old) with the basic IXT with equal dominance who underwent surgery were reviewed retrospectively, at least 18-month follow-up. including 48 patients underwent R&R surgery and 38 underwent BLR surgery at a single center. Surgical outcomes between groups were compared.
Results: No statistical difference was detected between BLR group and R&R group at all intervals with the exception of the last examination, demonstrating a higher success rate and a lower undercorrection rate in the BLR group than R&R group at the last visit (76.3% vs 60.4%, P =0.04; 15.8% vs 35.4%, P =0.04 ). Postoperative recurrence continued in the R&R group, and it was lower in the BLR group. Stereoacuity and control showed overall improvement following both surgeries for basic intermittent exotropia. but this improvement had no statistical difference between groups(P>0.05). Cumulative probability of survival was lower in the R&R group than in the BLR group (P =0.027, log-rank test).
Conclusions: The BLR group had a better outcome than R&R group at final visit, which may be due to the difference in the recurrence rate over time.
