duane syndrome rarity

Where most forms of strabismus leave side-to-side eye movements intact, in Duane syndrome the “wiring” of the eye muscles gets jumbled, and movement of eye(s) is limited in certain directions. … Occasionally, surgery is not needed during childhood, but becomes appropriate later in life, as head position changes (presumably due to progressive muscle contracture). (1994) described a 'new' contiguous gene syndrome resulting from a de novo 8q12.2-q21.2 deletion and characterized by the branchiootorenal (BOR) syndrome (), the Duane syndrome, hydrocephalus (), and aplasia of the trapezius muscle (see 600257).This was the first reported localization of the gene responsible for Duane syndrome. Duane syndrome has no particular race predilection. Duane syndrome is a rare eye condition where one or sometimes both eyes do not turn to the side very well and the eyelids may open and close as the eyes try to turn. This means that Duane Syndrome, or a subtype of Duane Syndrome, affects less than 200,000 people in the US population. Even ophthalmologists don't know anything about it. Conductive and sensorineural hearing loss are both prevalent among these children. Resende , Julio Z. Abucham-Neto 2, Mariza Polati 2, Gerson Chadi 1,Umbertina C.

In rare forms of Duane syndrome, there can also be other problems, for example with the person’s hands. [5], Duane syndrome is most probably a miswiring of the eye muscles, causing some eye muscles to contract when they shouldn't and other eye muscles not to contract when they should. General physical examination to assess for presence of other associated syndromes, including hearing evaluation. Generally, with treatment, eye movement can be corrected.

The Duane-Radial Ray syndrome or Okihiro syndrome belongs to the SALL4-Related Disorders, a phenotypic spectrum, that additionally includes, acrorenoocular syndrome and Holt-Oram syndrome, caused by the alteration of the same gene, which has significant relevance in the mesoderm, the limbs, and the heart development. This study presents a detailed characterization of hearing loss in patients with Duane's retraction syndrome. Duane syndrome falls under the larger heading of strabismus (misalignment of the eyes) under the subclassification of incomitant strabismus (misalignment of the eyes that varies with gaze directions) and subheading of extraocular fibrosis syndromes (conditions associated with fibrosis of the muscles that move the eyes). DS is a miswiring of the eye muscles, causing some eye muscles to contract when they shouldn't and other eye muscles not to contract … This unusual congenital form of strabismus was first described by Duane (1905), who collected reports of 54 cases.The condition is bilateral in 20% of cases. The ocular anomalies usually include Duane anomaly (see 126800), but this finding may be absent in some … Occasionally, torticollis in Duane syndrome can be satisfactorily corrected with spectacles alone. Thus, on attempted abduction, stimulation of the lateral rectus via the oculomotor nerve will be accompanied by stimulation of the opposing medial rectus via the same nerve; a muscle which works to adduct the eye. ), (Roque, B.L.,2018) Isolated Duane’s syndrome in familial and simplex cases has been identified worldwide. DS is represented in 2% between ocular disorders. You have limited ability to move your eye toward your ear. familial nature of the case.

Duane syndrome is a strabismus syndrome characterized by congenital non-progressive horizontal ophthalmoplegia (inability to move the eyes) primarily affecting the abducens nucleus and nerve and its innervated extraocular muscle, the lateral rectus muscle. The aims of surgery are to place the eye in a more central position and, thus, place the field of binocularity more centrally also, and to overcome or reduce the need for the adoption of an abnormal head posture. Duane Syndrome is an rare birth anomaly of the eyes in which the patient can't move the eye outward. In most patients, DS is diagnosed by the age of 10 years. The characteristic features of the syndrome are: While usually isolated to the eye abnormalities, Duane syndrome can be associated with other problems including cervical spine abnormalities Klippel–Feil syndrome, Goldenhar syndrome, heterochromia, and congenital deafness. The majority of patients remain symptom free and able to maintain binocularity with only a slight face turn. There are three types of Duane syndrome, but the most common … Truncating mutations and SALL4 gene deletions have been identifie… Synergistic divergence is a rare entity with features similar to those of Duane syndrome. They also noticed mechanical factors and considered them secondary to loss of innervation: During corrective surgery fibrous attachments have been found connecting the horizontal recti and the orbital walls and fibrosis of the lateral rectus has been confirmed by biopsy. Ophthalmologic examination focusing on primary gaze, head position, extraocular movements, and aberrant movements 3. Patients with Duane syndrome can have an accommodative component to their esotropia, which is crucial to detect and correct prior to surgery to decrease the risk of long-term over-correction. At birth, affected infants have restricted ability to move the affected eye(s) outward (abduction) and/or inward (adduction). 2007. Orbital wall fixation of the lateral rectus muscle (muscle is disinserted and reattached to lateral orbital wall) is recommended an effective method to inactivate a lateral rectus muscle in cases of marked anomalous innervation and severe cocontraction. It sometimes also includes various problems with accessory parts of the eye, such as ptosis, or leads to refractive errors, such as anisometropia, and finally convergence insufficiency, poor binocular vision.

Duane Syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). Duane syndrome (DS) is a rare, congenital (present from birth) eye movement disorder. This is due to a rare eye condition called Duane's Syndrome or DS. In each eye, two muscles move the eye horizontally. People with DS have a limited (and sometimes absent) ability to move the eye outward toward the ear (abduction) and, in most cases, a limited ability to move the eye inward toward the nose (adduction). Duane syndrome is a strabismus syndrome characterized by congenital non-progressive horizontal ophthalmoplegia (inability to move the eyes) primarily affecting the abducens nucleus and nerve and its innervated extraocular muscle, the lateral rectus muscle. Normal eye movements . This misdirection of nerve fibres results in opposing muscles being innervated by the same nerve. Duane Syndrome Duane syndrome is a rare congenital (occurring at birth) syndrome resulting in a disability of the child to carry out certain eye movements. [9], Brown(1950) has classified Duane's syndrome according to the characteristics of the limitation of movement-, The first type is more common and accounts for 85% of the cases.[5][10]. In the clinical setting, the principal difficulties in differential diagnosis arise as a consequence of the very early age at which patients with this condition first present.

Vertical Duane syndrome, a rare entity, has been described as limitation of the affected eye on elevation or depression associated with globe retraction and narrowing of the palpebral fissure. Head injury. REFERENCES 1. However, researchers have identified mutations in one gene, CHN1, that cause the disorder in a small number of families.The CHN1 gene provides instructions for making a protein that is involved in the early development of the nervous system.
