Duane Retraction syndrome
What are the symptoms?
In DRS there is an abnormality of horizontal eye movements resulting in restriction of the affected eye from turning outwards or inwards or in both directions. As the eye is turned in toward the nose (called adduction) the eyelids narrow as the eye is apparently drawn back (retracted). As the affected eye is turned outwards (abducted), the eye lids widen. There may be associated vertical eye movement changes causing an up shoot or down shoot.
Individuals who are affected with DRS may also have a squint (strabismus) when they look straight ahead. It is possible to have good vision in each eye with stereo vision. However, in order to maintain stereo vision, individuals with DRS may adopt a face turn.
