Optometric Vision Therapy in the Management of Amblyopia Associated with DRS-Type II: A Case Report.

Background: Duane retraction syndrome (DRS) is a congenital anomaly of the sixth cranial nerve and nucleus, resulting in limited abduction and/ or adduction of the affected eye and globe retraction and narrowing of the palpebral fissure on adduction.

Sumario:Background: Duane retraction syndrome (DRS) is a congenital anomaly of the sixth cranial nerve and nucleus, resulting in limited abduction and/ or adduction of the affected eye and globe retraction and narrowing of the palpebral fissure on adduction. Management to restore full- fledged ocular motility has been elusive. Case Report: An 8-year-old male, RK, visited our clinic with the complaint of outward deviation of the left eye, headache, and asthenopic symptoms. Upon examination, he was diagnosed with DRS-Type II with amblyopia. Vision therapy was started, which lasted for 3 months. A post-vision therapy binocular vision assessment showed marked improvement of visual acuity and other binocular parameters despite the presence of adduction limitations. Conclusion: Symptomatic patients with DRS may have amblyopia with compromised binocular vision functions. Optometric vision therapy must be considered as a first-line treatment, which helps patients to improve oculomotor control (saccades and pursuits), accommodative and vergence skills, stereopsis, visual-motor skill, and spatial processing.
