    Neurologic sequelae, including cranial nerve blockades and apnea, occurred in patients after retrobulbar anesthesia. These temporary effects resolved within hours, highlighting potential risks associated with reduced anesthesia coverage for eye surgery.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Anesthesiology

    Background:

    • Retrobulbar anesthesia is commonly used for ophthalmic procedures like cataract surgery.
    • Recent policy changes in some regions suggest reduced anesthesia coverage for these surgeries.

    Observation:

    • A series of eight patients experienced adverse neurologic events following retrobulbar anesthesia.
    • All patients exhibited blockade of one or more cranial nerves.

    Findings:

    • Six patients required intubation and mechanical ventilation due to apnea.
    • Neurologic deficits included contralateral amaurosis, nonreactive pupils, ductional defects, and dysphagia.
    • All reported sequelae resolved within 2 to 12 hours, with spontaneous respiration returning in 30-60 minutes for apneic patients.

    Implications:

    • The findings underscore the potential risks of retrobulbar anesthesia, even with temporary sequelae.
    • These results are significant given the trend towards reduced anesthesia staffing for ophthalmic surgeries.
    • Careful patient selection and monitoring are crucial when administering retrobulbar anesthesia.
