Duane Syndrome in Children: A Case Report

Abstract

Duane syndrome is a congenital ocular motility disorder caused by hypoplasia or agenesis of the abducens nerve, leading to limited outward gaze. The article reports the case of a 1-year-old child with inward strabismus in the left eye, with MRI showing the absence of the left abducens nerve. There are three types of Duane syndrome: type 1, inward strabismus with loss of outward gaze; type 2, outward strabismus with limited inward gaze; type 3, limitations in both gaze movements. The diagnosis of Duane syndrome primarily relies on clinical evaluation, but MRI aids in confirming abducens nerve agenesis. Treatment typically involves surgery to correct strabismus. High-resolution MRI is useful in the diagnosis and management of this syndrome.
