Duane retraction syndrome: A rare cause of strabismus.

ABSTRACT

Duane retraction syndrome (DRS) is a rare cause of strabismus in children. It has a characteristic ocular motility disorder and constitutes approximately 1% of all cases of strabismus. We describe a 9-year-old girl with absent or restricted horizontal eye movement, globe retraction and narrowing of the palpebral fissure on attempted adduction. DRS is classified into three types based on the different restrictions of ocular motility and can be associated with various ocular and systemic anomalies.
