BCVA, best-corrected visual acuity; LogMAR, logarithm of the minimum angle of resolution; SD, standard deviation.
For strabismic children without amblyopia, either the previously amblyopic eye or the right eye (if the child was never amblyopic) is listed for nonpreferred eye visual acuity. For normal control children, the right eye is listed for nonpreferred eye visual acuity.
In children treated strabismus without amblyopia, no differences were found on any reading measure between children who were never amblyopic (n = 8) and children who were previously treated for amblyopia (n = 15); P values ranged from 0.54 to 0.84).
