Summary

Topical anesthesia is a viable alternative to retrobulbar anesthesia for penetrating trabeculectomy, offering similar efficacy and patient-reported pain. This minimally invasive approach demonstrates clinical feasibility for glaucoma surgery.

Area of Science:

  • Ophthalmology
  • Surgical Anesthesia

Background:

  • Penetrating trabeculectomy is a surgical procedure to manage glaucoma.
  • Anesthesia choice impacts surgical outcomes and patient experience.

Purpose of the Study:

  • To compare the efficacy and clinical practicability of topical anesthesia versus retrobulbar anesthesia for penetrating trabeculectomy.

Main Methods:

  • A prospective clinical trial randomized 20 patients into topical (oxybuprocaine/cocaine eye drops) or retrobulbar (mepivacaine injection) anesthesia groups.
  • Intraoperative pain was assessed using a 10-point rating scale post-surgery.

Main Results:

  • No significant differences were observed between groups in surgery duration, preoperative/postoperative intraocular pressure, subjective pain scores, or surgeon-reported practicability.

  • Both anesthesia methods proved effective and well-tolerated.

    • Conclusions:

    • Topical anesthesia presents a feasible and minimally invasive option for penetrating trabeculectomy.
    • It may be considered as an alternative to retrobulbar anesthesia in select cases.
