The different types are distinguished by the eye movements that are most restricted. Duane syndrome type 1 is characterized by absent to very restricted abduction and normal to mildly restricted adduction. The eye opening (palpebral fissure) narrows and the eyeball retracts into the orbit with adduction. With abduction, the reverse occurs. One or both eyes may be affected.
