Screening corneal tomography as a helpful adjunct in the diagnosis of keratoconus in children with Down syndrome

Abstract

Keratoconus (KCN) is a bilateral progressive corneal ectasia characterized by the presence of irregular astigmatism and corneal thinning with possible visual impairment if not diagnosed and treated. This disease can have an aggressive course in pediatric patients and patients with Down syndrome (DS). We hypothesize that regardless of refractive error, we should screen children with DS using corneal tomography to detect keratoconus.
