[Partial rectus muscle transposition for strabismus with lateral rectus muscles paralysis]

Area of Science:

• Ophthalmology
• Surgical Techniques
• Strabismus Management

Context:

• Paralytic strabismus, particularly with lateral rectus muscle paralysis, presents significant challenges in achieving ocular alignment and binocular function.
• Traditional surgical approaches may have limitations in addressing complex paralytic strabismus cases.

Purpose:

• To investigate the efficacy of augmented partial rectus muscle transposition (APRMT) for paralytic strabismus involving lateral rectus muscle paralysis.
• To evaluate the clinical outcomes, including alignment, head posture, and visual field expansion, following APRMT.

Summary:

• A retrospective study analyzed 28 patients (31 eyes) who underwent APRMT for paralytic strabismus.
• The procedure, often combined with other muscle transpositions, demonstrated high success rates in achieving orthotopic alignment (17/28 patients).
• Significant improvements were observed in binocular single visual fields (27.0° to 40.5°) and ocular motility.

Impact:

• APRMT is a safe and effective surgical option for correcting paralytic strabismus with lateral rectus muscle paralysis.
• The technique successfully eliminates abnormal head posture and diplopia, expanding the patient's visual field.
• Rectus muscle forced traction testing is crucial for determining the optimal surgical strategy.
