Partial central retinal artery occlusion.

E O Oji, D McLeod

    Transactions of the Ophthalmological Societies of the United Kingdom
    |April 1, 1978

    Summary
    This summary is machine-generated.

    Partial occlusion of the central retinal artery causes cotton-wool spots and inner retinal swelling. Interrupted axoplasmic transport is key to developing these fundus signs.

    Area of Science:

    • Ophthalmology
    • Retinal Vascular Diseases

    Background:

    • Cotton-wool spots and inner retinal swelling indicate retinal ischemia.
    • Central retinal artery occlusion (CRAO) is a critical cause of vision loss.

    Purpose of the Study:

    • To explain the clinical findings of cotton-wool spots and retinal swelling.
    • To discuss the pathophysiology of these signs in partial CRAO.

    Main Methods:

    • Clinical observation of fundus signs.
    • Pathophysiological analysis of retinal ischemia.

    Main Results:

    • Multiple circumpapillary cotton-wool spots are characteristic.
    • Mild ischemic swelling of the inner retina is observed.

    Conclusions:

    • Partial central retinal artery occlusion is the cause.
    • Interrupted axoplasmic transport plays a crucial role in cotton-wool spot formation.
