Studies of strabismus and amblyopia in infant monkeys.

Longitudinal studies of grating acuity have been conducted with strabismic infant monkeys. Representative data from several different monkey models of strabismus are presented. Acuity in the fixating eyes of these monkeys developed to adult levels similarly to acuity development in normal infant monkeys. Acuity in the non-fixating eyes often lagged behind, and in some cases never reached normal levels, resulting in a permanent amblyopia.
