Duane retraction syndrome in a patient with abnormal head position.

Abstract

Duane’s syndrome is a rare retraction anomaly characterized by an innervation defect in the lateral rectus muscle, limitation of abduction and adduction due to the result of abnormal innervation of the horizontal rectus muscles, changes in the eyelid fissures, and abnormal vertical eye movements. The affected eye is displaced up and/or down in adduction. This syndrome, also known as Stilling-Turk-Duane syndrome, accounts for approximately 1 to 5% of all strabismus cases. In this article, we present a one-and-a-half-year-old male patient who had abnormal head position, and was diagnosed as having Duane retraction syndrome. Through this study, we want to draw attention to Duane retraction syndrome, which is one of the rare causes of strabismus.
