Peribulbar anesthesia is effective for vitreoretinal surgery, particularly vitrectomy. While less effective for scleral buckling alone or combined procedures, supplementation allows high success rates and patient satisfaction.

Area of Science:

  • Ophthalmology
  • Anesthesiology

Background:

  • Peribulbar anesthesia is an alternative to general anesthesia for ocular surgeries.
  • Vitreoretinal surgery encompasses procedures like vitrectomy and scleral buckling.

Purpose of the Study:

  • To evaluate the efficacy of peribulbar anesthesia in patients undergoing vitreoretinal surgery.
  • To assess the success rates of peribulbar anesthesia for different types of vitreoretinal procedures.

Main Methods:

  • Prospective study of 76 patients undergoing vitreoretinal surgery.
  • Assessment of anesthesia and akinesia duration and adequacy.
  • Evaluation of supplemental medication use and operative complications.

Main Results:

  • Adequate anesthesia and akinesia were achieved in 78.8% of vitrectomy, 28.1% of scleral buckling, and 18.2% of combined surgery patients.

  • Supplemental medications allowed completion of 97% of vitrectomies, 94% of scleral buckling, and 100% of combined surgeries.
  • Only 4% of patients experienced complications due to inadequate anesthesia or akinesia.

    • Conclusions:

    • Peribulbar anesthesia is highly effective for vitrectomy.
    • It can be considered for scleral buckling or combined surgeries when general anesthesia is contraindicated.
    • Patient satisfaction with peribulbar anesthesia was high (76%).
