Any	2.6% (44) (1.8–3.4)	1.5% (25) (0.9–2.1)
Unilateral anisometropic	1.5% (25)	0.8% (14)
Unilateral strabismic	0.4% (6)	0.2% (4)
Unilateral combined strabismic/anisometropic	0.2% (3)	0.0% (0)
Unilateral deprivational	0.1% (1)	0.0% (0)

CI = confidence interval.

^*Reported by race/ethnicity for overall amblyopia prevalence only.

^†One African American child had bilateral aphakia with a history of congenital cataracts; all other cases of bilateral amblyopia were due to bilateral ametropia alone. One additional African American child with high myopia was classified as having unilateral amblyopia but also met the criteria for bilateral amblyopia.
