The oculocardiac reflex: a review

M D Van Brocklin, R R Hirons, R L Yolton

    Journal of the American Optometric Association
    |May 1, 1982
    PubMed
    Summary

    The oculocardiac reflex (OCR) can cause cardiac arrest during eye surgery. While preventive measures exist, this reflex remains a significant concern for eye care professionals.

    Area of Science:

    • Ophthalmology
    • Cardiology
    • Anesthesiology

    Background:

    • The oculocardiac reflex (OCR) is a physiological response linked to cardiac events during ocular procedures.
    • It can be triggered by pressure or traction on orbital structures, including the eye and extraocular muscles.

    Purpose of the Study:

    • To review the established pathways of the oculocardiac reflex.
    • To discuss preventive strategies and the continued relevance of OCR in optometry.

    Main Methods:

    • Review of established literature on the oculocardiac reflex pathways.
    • Discussion of preventive interventions such as retrobulbar blocks and atropine administration.

    Main Results:

    • The oculocardiac reflex is a known risk factor for cardiac arrest in ophthalmic surgery.
    • Preventive methods and advancements in anesthesia have likely reduced the incidence of fatal events.
    • Despite reduced fatalities, the reflex warrants continued attention in optometric practice.

    Conclusions:

    • The oculocardiac reflex, though mitigated by modern medical practices, remains a critical consideration in ophthalmic surgery.
    • Understanding OCR pathways and prevention is essential for patient safety in eye care.
    • The reflex continues to be a subject of optometric interest due to its potential impact on patient outcomes.
