Transposition procedures in Duane retraction syndrome.

Area of Science:

• Ophthalmology
• Neurology
• Congenital Cranial Dysinnervation Disorders

Background:

• Duane syndrome (DS) is a congenital disorder affecting eye movement.
• It is characterized by limited horizontal eye movement and globe retraction with eyelid narrowing during adduction.
• This occurs due to co-contraction of the lateral and medial rectus muscles.

Purpose of the Study:

• To review surgical transposition procedures for Duane syndrome.
• To discuss indications, strengths, and weaknesses of various techniques.
• To focus on unilateral esotropic DS while acknowledging other forms.

Main Methods:

• Review of proposed surgical approaches for Duane syndrome.
• Discussion of transposition techniques involving vertical rectus muscles (VRT, SRT, IRT).
• Consideration of augmentation techniques like posterior fixation sutures and medial rectus weakening.

Main Results:

• Various transposition techniques exist, involving one or both vertical rectus muscles.
• Procedures can include full/partial disinsertion and augmentation with sutures or muscle weakening.
• The review evaluates the effectiveness and considerations for each approach in DS.

Conclusions:

• Surgical transposition offers options to improve binocular alignment and reduce symptoms in Duane syndrome.
• The choice of technique depends on specific patient factors and desired outcomes.
• This review provides a comprehensive overview of surgical management strategies for DS.
