Summary

Strabismus surgery detaching vertical and medial rectus muscles can cause anterior segment ischemia in adults. Most patients recovered fully, indicating this complication is linked to specific muscle detachments in strabismus procedures.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Oculomotor Muscle Surgery

Background:

  • Strabismus surgery, particularly involving rectus muscle detachment, is a common ophthalmological procedure.
  • Sixth nerve palsy and Duane's retraction syndrome are conditions often treated with rectus muscle surgery.
  • Understanding potential postoperative complications is crucial for patient management and surgical planning.

Observation:

  • Nine patients underwent detachment of vertical and medial rectus muscles for strabismus.
  • Five adult patients developed clinically significant anterior segment ischemia postoperatively.
  • Preexisting medical risk factors were uncommon in affected patients.

Findings:

  • Anterior segment ischemia occurred in 5 of 9 adult patients undergoing specific rectus muscle detachments.

  • The complication was observed even when few medical risk factors were present.
  • Most patients experienced full visual recovery within nine weeks, with corectopia as the main sequela.

    • Implications:

    • Anterior segment ischemia may be a more frequent complication of strabismus surgery in adults than previously recognized.
    • Surgeons should be vigilant for this complication when detaching superior, inferior, and medial rectus muscles.
    • This finding highlights the importance of careful surgical technique and patient monitoring in adult strabismus surgery.
