Table 3. Postoperative surgical outcomes at distant fixation in the BLR group and the RR group treated for basic-type intermittent exotropia.

Values are presented as number (%).

BLR = bilateral lateral rectus muscle recession; RR = unilateral lateral rectus recession-medial rectus resection; Δ = prism diopters.

^*Overcorrection = esophoria/tropia >8Δ at a distance; success = esophoria/tropia ≤8Δ to exophoria/tropia ≤8Δ at a distance; undercorrection/recurrence = exophoria/tropia >8Δ at a distance. All patients who underwent reoperation for a recurrence of exotropia were also included in “Recurrence” category; ^†Statistics by Pearson's chi-square test; ^‡Statistics by Fisher exact test.
