Unilateral posterior polymorphous corneal dystrophy associated with ipsilateral anisometropic amblyopia.

Posterior polymorphous corneal dystrophy is typically considered asymptomatic unless visual opacity develops. However, some have suggested that asymmetric disease without visual opacity might be associated with asymmetric refractive error, which would have the potential to be the cause of amblyopia in young children. In support of this concept, a case of unilateral posterior polymorphous dystrophy with ipsilateral anisometropic amblyopia is reported.
