Does Duane syndrome go away?
Because the affected sixth cranial nerve cannot be repaired or replaced, there is no cure for Duane syndrome. However, for people whose lives are significantly disrupted by the condition, surgery can be very helpful in: reducing or stopping the abnormal head posture many develop in an attempt to see better.
How many people are diagnosed with Duane syndrome?
Isolated Duane retraction syndrome affects an estimated 1 in 1,000 people worldwide. This condition accounts for 1 percent to 5 percent of all cases of abnormal eye alignment (strabismus). For unknown reasons, isolated Duane syndrome affects females more often than males.
How is Duane syndrome diagnosed?
The diagnosis of Duane syndrome is based on clinical findings. Mutations in the CHN1 gene are associated with familial isolated Duane syndrome. Direct sequencing of the CHN1 gene is available as a clinical test, and has to date detected missense mutations in seven patients and affected family members.
What is the history of Duane syndrome?

Can you get surgery to fix Duane syndrome?
There’s no cure for Duane syndrome, but surgery can be used to try to improve or eliminate issues with head turns, reduce or completely remove considerable misalignment of the eyes, reduce severe retraction of the eyeball, and improve the tendency of the eye to deviate upward or downward with particular eye movements.
How does Duane syndrome affect a person?
Duane syndrome affects the ability of the eye to move from side to side. Symptoms include restricted movement of eye outward and/or inward and the eyeball may be pulled back into the socket. In addition, the opening of the eye may be narrow.
Are you born with Duane syndrome?
Duane syndrome is present at birth and infants may have only a limited ability to move the affected eye outward and/or inward. Some people with Duane syndrome are at risk to develop lazy eye and have decreased vision in that eye. People with Duane syndrome may also have unusual head movements.
What does Duane syndrome look like?
It presents as an eye movement disorder in which an individual’s affected eye is unable to look inward toward the nose and up. The affected eye may be out of alignment with the unaffected eye and may show a downshoot and/or a widening of the eye opening when looking inward and up.
Can Duane syndrome cause other problems?
Not usually, however, some patients with Duane syndrome have other problems, such as hearing impairment, Goldenhar syndrome, spinal and vertebral abnormalities. There is also an increased frequency of Duane syndrome in patients with thalidomide exposure.
The syndrome was first described by ophthalmologists Jakob Stilling (1887) and Siegmund Türk (1896), and subsequently named after Alexander Duane, who discussed the disorder in more detail in 1905. Other names for this condition include: Duane’s retraction syndrome, eye retraction syndrome, retraction syndrome,…
