How to Treat Duane Syndrome?

What is Duane Syndrome?

Duane Syndrome, classified as a subtype of congenital strabismus, manifests as a distinctive form of inherent eye misalignment. Individuals affected by Duane syndrome grapple with impediments in horizontal eye movement, experiencing challenges both in inward (adduction) and outward (abduction) gazes. Moreover, the disorder extends its impact to compromise upward and downward eye movements. In tandem with ocular misalignment, Duane syndrome presents a unique feature – eyelid movements during attempted eye motions. This phenomenon is a consequence of irregular nerve signaling to the eye muscles, indicative of the condition's underlying neurological origins.

Named after Alexander Duane, who documented it in 1905, Duane Syndrome is recognized for its early onset, typically appearing in childhood. The disorder stems from abnormal developmental patterns in the eye muscles, leading to the characteristic limitations in eye movement. Notably, this congenital eye movement disorder predominantly affects one eye, with approximately 80% to 90% of cases being unilateral. The left eye is more commonly impacted, underscoring the distinct asymmetry often associated with Duane Syndrome.


Why Does Duane Syndrome Occur?

The precise cause of Duane Syndrome remains unclear, but it is generally considered a result of abnormal development of the ocular muscles and nerves during fetal development. Genetic factors may contribute, as the condition sometimes occurs within families. While Duane Syndrome is typically present at birth, its impact on vision and eye movement can vary.
