*P-value using Pearson’s χ2 test; **P-value using a two-sample t-test; †P-value using a Mann–Whitney U test. Data are presented as the mean (standard deviation) unless otherwise indicated. IXT, intermittent exotropia; M–W U, Mann–Whitney U; NA, not available; BCVA, best-corrected visual acuity; logMAR, logarithm of the minimum angle of resolution; OD, right eye, OS, left eye.
