What Is Duane Syndrome?
Duane syndrome (DS) is a rare, congenital (present from
birth) eye movement disorder. Most patients are diagnosed by
the age of 10 years and DS is more common in girls (60 percent
of the cases) than boys (40 percent of the cases).
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 when they should.
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).
Often, when the eye moves toward the nose, the eyeball also
pulls into the socket (retraction), the eye opening narrows
and, in some cases, the eye will move upward or downward.
Many patients with DS develop a face turn to maintain
binocular vision and compensate for improper turning of the
eyes.
