Central retinal artery spasm.

W T Humphrey

    Annals of Ophthalmology
    |June 1, 1979

    Summary
    This summary is machine-generated.

    Central retinal artery spasm, a rare ocular sign, can cause temporary monocular blindness. Treating carotid artery plaque resolved symptoms, suggesting a link between atherosclerosis and vision loss.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Medicine

    Background:

    • Central retinal artery spasm is an uncommon ocular finding.
    • Transient monocular blindness (TMB) can be caused by various factors.
    • Carotid artery disease is a known risk factor for cerebrovascular events.

    Observation:

    • A patient presented with TMB in one eye, accompanied by central retinal artery spasm.
    • No other ocular pathologies were identified.
    • An ulcerative atheromatous plaque was found in the ipsilateral carotid artery.

    Findings:

    • Surgical removal of the carotid artery plaque led to complete resolution of the TMB and retinal artery spasm.
    • This case highlights a potential direct link between carotid atherosclerosis and retinal artery spasm.

    Implications:

    • Simultaneous bilateral central retinal artery spasm may explain amaurosis fugax.
    • Atherosclerosis and carotid artery obstructive disease may contribute to transient visual disturbances.
    • Central retinal artery spasm could potentially trigger vessel occlusion.
