Overview

Duane syndrome type 1 is the most common type of Duane syndrome, an eye movement disorder that is present at birth.[1] People with Duane syndrome have restricted ability to move the affected eye(s) outward toward the ear (abduction) and/or inward toward the nose (adduction). The different types are distinguished by the eye movements that are most restricted.[1][2] Duane syndrome type 1 is characterized by absent to very restricted abduction and normal to mildly restricted adduction.[1] The eye opening (palpebral fissure) narrows and the eyeball retracts into the orbit with adduction. With abduction, the reverse occurs.[3] One or both eyes may be affected. The majority of cases are sporadic (not inherited), while about 10% are familial. 70% of affected people do not have any other abnormalities at birth (isolated Duane syndrome).[1]
