A Comprehensive Guide To Duane Syndrome

Types Of Duane Syndrome And Characteristics

SeaGullFoundation

How Duane syndrome presents itself depends on the type the individual has. Typically only one eye is affected, though it is possible for both to be compromised.

Type 1, the most common, is characterized by the affected eye’s limited ability to move outwards towards the individual’s ear. The eye’s ability to move inwards is either entirely normal or close to it. In Type 1, the affected eye opening will narrow, and the eyeball will pull in when the patient looks inward. The reverse of this occurs when looking outward. Type 2, the rarest, is characterized by the affected eye’s limited ability to move inwards towards the nose and the usual ability to move outwards. In this type, the eye-opening will narrow, and the eyeball will pull in when the patient looks towards the nose. The affected eye in Type 3 has a limited ability to move both outwards and inwards. Like the other types, in Type 3 the eye-opening will narrow, and the eyeball will pull in when the patient looks inward.
