Summary

Perilimbal anesthesia with monitored anesthesia care is effective for pars plana vitrectomy in selected patients. This technique avoids risks associated with general anesthesia and other anesthetic methods.

Area of Science:

  • Ophthalmology
  • Anesthesiology

Background:

  • Pars plana vitrectomy is a common surgical procedure for various vitreoretinal conditions.
  • Traditional anesthesia methods like retrobulbar or general anesthesia carry specific risks.

Purpose of the Study:

  • To evaluate the efficacy and safety of perilimbal anesthesia combined with Monitored Anesthesia Care (MAC) for pars plana vitrectomy.

Main Methods:

  • A cohort of 15 selected patients aged 55-79 underwent pars plana vitrectomy.
  • Patients excluded had conditions precluding supine positioning or requiring reoperation.
  • Anesthesia was administered via perilimbal approach with MAC (intravenous sedation and vital sign monitoring).

Main Results:

  • All surgeries were completed successfully without the need for additional anesthesia.

  • No patient reported discomfort during the procedure.
  • Operating times ranged from 45 to 135 minutes (mean 102.3 minutes).

    • Conclusions:

    • Perilimbal anesthesia with MAC is an effective anesthetic option for selected patients undergoing pars plana vitrectomy.
    • This method mitigates risks of globe perforation and general anesthesia complications.
