Duane syndrome is an eye movement disorder present at birth characterized by straight eye movement restriction: a limited ability to move the eye internal toward the nose, outward towards the ear, or in both instructions. The eyeball pulls back and the eye opening tightens when the affected eye relocations internal towards the nose. The 3 types of Duane syndrome present as follows: Duane syndrome type 1: The ability to move the affected eye outside towards the ear is limited, yet the ability to move the affected eye internal towards the nose is normal or nearly so. DS does not cause blindness and does not usually lead to other wellness problems. Women are slightly most likely to have DS than men. There are 3 types of DS: Type 1: People with this type aren't able to move their affected eye out towards their ear. Eyelid constricting: One eye may look smaller sized than the other. Minimized vision in the affected eye: One out of every 10 people who have DS have "lazy" eye, a condition called amblyopia. Head position: People that have DS might turn or transform their heads to try to keep their eyes straight. Some people with DS have dual vision and headaches. You may have neck pain as an outcome of tilting our head. Duane syndrome is a miswiring of the eye muscles, creating some eye muscular tissues to contract when they shouldn't and other eye muscular tissues not to contract when they should. Many patients with DS develop a face turn to preserve binocular vision and make up for inappropriate turning of the eyes. However, in some cases, both eyes are affected, with one eye usually more affected than the other.
