Duane Syndrome – What it is, Symptoms and Treatments that many are still unaware of. Also, Duane Syndrome  is a rare eye disease . It is characterized by a disturbance of eye movement.

This condition limits horizontal eye movement, ie from the eye outward (abduction) toward the ear, but there are some cases where the limitation occurs with inward movement (adduction) toward the nose. In general only one eye is affected.

Duane Syndrome Types:

There are three types of Duane Syndrome according to the limitation presented:

Type I: There is limitation on abduction;

Type II: there is limitation on adduction;

Type III: There is limitation in both (abduction and adduction).

The most common is type I.

Causes of Duane Syndrome:

The Duane syndrome is an acquired disease from birth, caused by changes in oculomotor third nerve, in some cases, it is due to the absence of head Friday, known as abducens.

This syndrome is usually associated with Klippel-Feil Syndrome that causes malformations on the face, teeth and ears, is autosomal.

The Duane syndrome usually causes strabismus and stiff neck this is due to the position to be taken by the person who has this disorder and movements to do to get a better visual field.

Duane Syndrome Symptoms:

Amblyopia;

Loss of sight;

Eye misalignment ;

Retraction of the affected eye (when looking inwards – adduction);

Abnormal position of the head;

Limitation of horizontal eye movement:

Outer movement;

Inner movement;

Inner and outer movement (simultaneously);

Narrow eyelid fissure (during adduction, the eyeball pulls the eye opening, narrowing it).

Duane Syndrome Treatment:

Treatment of Duane Syndrome usually involves correction surgery. Main goals of surgery:

Eliminate or improve the abnormal position of the head;

Eliminate or reduce eye misalignment;

Reduce retraction when the eye rotates inward;

Improve vertical eye movement that may be affected in certain movements of the globe.

To date no specific surgical technique has been completely successful in eliminating abnormal eye movements. However, some of the procedures used have shown significant benefits.

The choice of the most appropriate intervention depends on the case and the individual. The success rate in surgery to eliminate abnormal head position is estimated at 79 to 100%.
