Summary

Single-stage adjustable strabismus surgery (SSASS) offers a safe and precise method for correcting restrictive strabismus. This technique, using local anesthesia, achieved good ocular alignment in most patients, including those with dysthyroid orbitopathy.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Strabismus Management

Background:

  • Restrictive strabismus presents unique surgical challenges.
  • Previous surgical interventions may complicate strabismus correction.
  • Dysthyroid orbitopathy is a common cause of restrictive strabismus.

Purpose of the Study:

  • To assess the feasibility and stability of ocular alignment using single-stage adjustable strabismus surgery (SSASS).
  • To evaluate SSASS in patients with restrictive strabismus, including those with dysthyroid orbitopathy.

Main Methods:

  • An observational case series of 12 patients with restrictive strabismus undergoing SSASS under local anesthesia.
  • Adjustments were primarily made to vertical rectus muscles, with horizontal muscles adjusted as needed.

  • Ocular alignment was assessed at 2 days, 6 weeks, and 3 months post-surgery.

    • Main Results:

    • All patients tolerated the SSASS procedure well with minimal discomfort.
    • Satisfactory vertical alignment (<2 prism diopters) was achieved in 83.4% of patients.
    • Two patients with dysthyroid orbitopathy experienced progressive overcorrection following inferior rectus recession.

    Conclusions:

    • Single-stage adjustable strabismus surgery (SSASS) is a safe and precise treatment option for restrictive strabismus.
    • SSASS is effective even in complex cases, including those with dysthyroid orbitopathy.
    • The technique demonstrates good stability of ocular alignment post-operatively.
