Contact Us Duane syndrome Duane syndrome with radial ray anomalies DURS2 locus DURS1 locus Research: Duane syndrome Duane syndrome (DS) is an eye movement disorder present at birth (congenital) characterized by a limited ability to move an eye inward towards the nose (adduction), outward towards the ear (abduction), or in both directions. In addition, when the affected eye(s) move inward towards the nose, the eyeball retracts (pulls in) and the eye opening (palpebral fissure) narrows. In some cases when the eye attempts to look inward, it moves upwards (upshoot) or downwards (downshoot). Similar to CFEOM, Duane syndrome falls under the larger heading of strabismus (misalignment of the eyes) under the subclassification of incomitant strabimsus (misalignment of the eyes which varies with gaze directions) and subheading of extraocular muscle fibrosis syndromes (conditions associated with restriction of both active and passive movement of the eyeball). Although "muscle fibrosis" suggests that syndromes under this heading are primary disorders of muscle, evidence suggests that DS (and other Congenital Cranial Dysinnervation Disorders-CCDD's) may actually be primary disorders of nerve innervation

Extractions: Duane Retraction Syndrome Definition: A syndrome characterized by marked limitation of abduction of the eye, variable limitation of adduction and retraction of the globe, and narrowing of the palpebral fissure on attempted adduction. The condition is caused by aberrant innervation of the lateral rectus by fibers of the oculomotor nerve. There are three subtypes: type 1 (associated with loss of abduction), type 2 (associated with loss of adduction), and type 3 (loss of abduction and adduction). Two loci for Duane retraction syndrome have been located, one at chromosome 8q13 (DURS1) and another at chromosome 2q31(DURS2). It is usually caused by congenital hypoplasia of the abducens nerve or nucleus, but may rarely represent an acquired syndrome.

It may occur from active co-contraction of the horizontal rectus muscles such as in Duane retraction syndrome. Patients with Duane syndrome have strabismus, upshooting or downshooting eye movements, and narrowing of palpebral fissure and retraction of globe on adduction. Enlargement of orbital cavity after orbital blowout fractures also may cause the globe to be retracted. It may be due to prolapse of orbital contents into adjacent sinuses, atrophy of orbital fat, or contracture of necrotic extraocular muscles entrapped within the fracture. Globe retraction also can be seen in metastatic scirrhous breast carcinoma from cicatrization of orbital tissue. Although less common, some cases of sclerosing orbital pseudotumor have been reported to cause globe retraction. A thorough history and examination are required to determine appropriate management for patients with globe retraction.

Duane Retraction syndrome: Duane syndrome; DRS Duane Retraction syndrome is a congenital disorder of ocular movements which was first described in 1905. There are three types of DRS that share common features. The condition may affect one or both eyes. DRS more commonly affects the left eye and is more common in girls. The reasons for this are not yet known. In DRS there is an abnormality of horizontal eye movements resulting in restriction of the affected eye from turning outwards or inwards or in both directions. As the eye is turned in toward the nose (called adduction) the eyelids narrow as the eye is apparently drawn back (retracted). As the affected eye is turned outwards (abducted), the eye lids widen. There may be associated vertical eye movement changes causing an up shoot or down shoot. Individuals who are affected with DRS may also have a squint (strabismus) when they look straight ahead. It is possible to have good vision in each eye with stereo vision. However, in order to maintain stereo vision, individuals with DRS may adopt a face turn.
