Duane syndrome (DS) is an eye movement disorder present at birth (congenital) characterized by horizontal eye movement limitation: a limited ability to move the eye inward toward the nose (adduction), outward toward the ear (abduction), or in both directions. Duane retraction syndrome is a congenital eye movement disorder characterized by a failure of cranial nerve VI (the abducens nerve) to develop normally, resulting in restriction or absence of abduction, adduction, or both, and narrowing of the palpebral fissure and retraction of the globe on attempted adduction.

The syndrome can be inherited as an autosomal dominant or recessive trait. Duane syndrome encompasses a spectrum of strabismus entities that have as common features: mis‐innervation and co‐contraction of extraocular muscles in addition to enophthalmos with palpebral fissure narrowing.1‐3 Other findings often Duane syndrome is caused by an absence of or a problem with the operation of the 6th cranial nerve. Duane syndrome is the most common of the CCDDs, accounting for 1% to 5% of strabismus cases.

In all cases, a person with Duane syndrome will have little, or no, ability to look outwards (toward their ears) and often have limited ability to look inwards (towards their nose). Also, patients with Duane syndrome lack the abducens nerve, the sixth cranial nerve, which is involved in eye movement. It is also seen as part of other syndromes such as Goldenhar ( 164210 ), and Wildervanck ( 314600 ).
