Measuring and interpreting the incidence of congenital ocular anomalies: lessons from a national study of congenital cataract in the UK.

Abstract

These estimates of congenital and infantile cataract incidence were higher than reported previously from routine sources relying on passive notification around the time of birth. Studies of congenital ocular anomalies that are not always readily diagnosed at birth should consider the potential influence on disease frequency of diagnostic practices as well as of underlying disease risk.
