-
- Duane Syndrome is an eye disorder characterized by limitations in the movement
- of the eye needed to focus. It is hereditary and most commonly affects males.
-
- Symptoms
-
- Duane Syndrome is generally restricted to one eye. The affected eye shows
- defective horizontal mobility. The ability to move the eye away from the
- center (abduction) is reduced or absent. Movement of the eye toward the
- center (adduction) is limited, and there may be weakness in focusing
- (convergence). Attempted eye movements result in retraction of the eyeball.
- An abnormally small eye (microphthalmus), an unusually small cornea
- (microcornea), and a conically shaped cornea (keratoconus) may also often
- occur.
-
- The disorder is not degenerative and the symptoms remain stationary.
-
- Causes
-
- Duane Syndrome is an autosomal dominant hereditary disorder. (Human traits
- including the classic genetic diseases, are the product of the interaction of
- two genes for that condition, one received from the father and one from the
- mother. In dominant disorders, a single copy of the disease gene (received
- from either the mother or father) will be expressed "dominating" the normal
- gene and resulting in appearance of the disease. The risk of transmitting
- the disorder from affected parent to offspring is 50% for each pregnancy
- regardless of the sex of the resulting child.)
-
- Innervation of the nerves that cause eye movements and of the facial
- nerve is abnormal in this disorder.
-
- Affected Population
-
- Duane Syndrome occurs more frequently in males than in females.
-
- Related Disorders
-
- Duane Syndrome may sometimes occur in conjunction with the following
- disorders.
-
- 1. Holt-Oram Syndrome, a hereditary heart disease (usually an atrial or
- septal defect) associated with skeletal malformation.
-
- 2. Klippel-Feil Syndrome, characterized by fused cervical vertebrae, and
- many other symptoms in addition to those of Duane Syndrome.
-
- 3. Spina Bifida Cervicalis, a developmental abnormality characterized by
- defective closure of the vertebral bones over the spinal cord in the neck
- area.
-
- Therapies: Standard
-
- Treatment of Duane Syndrome is symptomatic and supportive.
-
- Therapies: Investigational
