The sensitive period for anisometropic amblyopia.

Fifty-five children with pure anisometropic amblyopia presented consecutively between 1983 and 1986. Analysis of their records was undertaken with respect to the age at presentation, the initial visual acuity after spectacle correction, and the final acuity attained after treatment. The results show that the final vision achieved does not depend on the age at presentation. The implications of these findings are discussed and their relations to the sensitive period for the development of amblyopia from other causes outlined.
