To an ophthalmologist, this is powerful justification for the Academy's recommendations for preschool screening and the similar advice promulgated, for years in some cases, by those devoted to pediatric and ocular health care.2-4 The potential development of irreversible amblyopia can be considered the driving force for screening programs.

Possible associated conditions include refractive errors, strabismus, and cataract.
