    Summary
    This summary is machine-generated.

    This study presents an adjustable Harada-Ito procedure for superior oblique palsy, effectively treating excyclotorsion without inducing vertical deviation. The adjustable suture allows precise correction, resolving torsional symptoms and improving patient comfort.

    Area of Science:

    • Ophthalmology
    • Strabismus Surgery
    • Neuro-ophthalmology

    Background:

    • Superior oblique palsy can cause symptomatic excyclotorsion, often without significant vertical deviation.
    • Traditional surgical techniques may not offer precise control over torsional correction.

    Observation:

    • Four patients with superior oblique palsy and symptomatic excyclotorsion underwent surgery.
    • The procedure involved anteriorizing and lateralizing superior oblique tendon fibers using an adjustable suture (adjustable Harada-Ito procedure).

    Findings:

    • Postoperative adjustments of the suture effectively eliminated excyclotorsion in all patients.
    • No new vertical deviation was induced, and no limitation of elevation in adduction was observed.
    • Follow-up ranged from two to 20 months, with sustained symptom relief.

    Implications:

    • The adjustable Harada-Ito procedure offers enhanced precision for correcting excyclotorsion in superior oblique palsy.
    • This technique minimizes or eliminates symptomatic complaints related to torsional deviation.
    • It provides a valuable option for surgeons managing complex strabismus cases.
