With the increasing number of infants born exposed to cocaine, we are confronted with a problem whose extent has not yet been evaluated. In this study, the Preferential Looking Acuity Card Procedure was used to assess the visual acuity of four infants exposed to cocaine in utero. Binocular function was evaluated utilizing a cover test, Hirschberg, and Bruckner test for strabismus and amblyopia. No correlation was found between cocaine exposure and decreased visual acuity or increased incidence of strabismus.
