Comitant Horizontal Strabismus in South African Black and Mixed Race Children—A Clinic-based Study

Abstract

Congenital esotropia remains common in South African black children, and of the few who presented with exotropia, most had constant type. Accommodative esotropias were more prevalent in South African mixed race children, but in smaller proportions than in other studies. Exotropias were mostly intermittent in this ethnic group, and showed a similar profile to that in white American children.
