    Summary

    The single-injection peribulbar block is a safe and effective anesthesia method for anterior segment eye surgery. This technique demonstrated a low rate of sight-threatening complications in a large prospective study.

    Area of Science:

    • Ophthalmology
    • Anesthesia

    Background:

    • Peribulbar block is a common anesthesia technique for anterior segment eye surgery.
    • Ensuring effective anesthesia and akinesia is crucial for successful ophthalmic procedures.

    Purpose of the Study:

    • To evaluate the safety and efficacy of a single-injection peribulbar technique.
    • To determine the incidence of complications and need for supplemental anesthesia.

    Main Methods:

    • Prospective study of 2,684 consecutive cases.
    • Single-injection peribulbar block performed over three years.
    • Data collection on complications and supplemental anesthesia requirements.

    Main Results:

    • A low incidence of 0.6% for sight-threatening complications.
    • No cases were canceled due to peribulbar hemorrhage.
    • Only 1.2% of patients required supplemental anesthesia.

    Conclusions:

    • The single-injection peribulbar technique is a highly effective and safe method for anesthesia and akinesia in anterior segment eye surgery.
    • This technique minimizes the risk of serious complications and the need for additional anesthesia.
