What causes Duane syndrome?
Duane syndrome is caused by an abnormality in the early development of the cranial nerve involved in eye movement. The exact cause for this is unknown. Duane syndrome usually occurs in a family for the first time, without any previous family history . In some cases, Duane syndrome is inherited from an affected parent.
How does Duane syndrome affect the body?
Isolated Duane retraction syndrome is a disorder of eye movement. This condition prevents outward movement of the eye (toward the ear), and in some cases may also limit inward eye movement (toward the nose). As the eye moves inward, the eyelids partially close and the eyeball pulls back (retracts) into its socket.
Is Duane syndrome hereditary?
What do we know about heredity and Duane syndrome? Most likely, both genetic and environmental factors play a role in the development of Duane syndrome (DS). For those cases that show evidence of having a genetic cause, both dominant and recessive forms of DS have been found.
How many people in the US have Duane syndrome?
Duane retraction syndrome (DRS) prevalence is estimated at between 1/1000 and 1/10,000 in the general population, representing approximately 1-5\% of all strabismus cases. Females are more frequently affected than males.
How do you fix Duane syndrome?
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.
Can you prevent 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.

Duane syndrome type 3: The ability to move the affected eye(s) both inward toward the nose (adduction) and outward toward the ear (abduction) is limited. The eye opening narrows and the eyeball retracts when the affected eye(s) attempts to look inward toward the nose (adduction).

Is Duane syndrome a birth defect?
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.
