Abduction Deficits in Strabismus: Differential Diagnosis

Abstract

The differential diagnosis for abduction deficits in strabismus includes many disorders. While some conditions are described for an abduction deficit, many have only an associated abduction limitation as part of their spectrum of clinical findings. The classifications of abduction deficits can be divided into congenital and acquired disorders and further categorized as traumatic, restrictive, or metabolic.
