Choroidal ischemia

A Gaudric, G Coscas, A C Bird

    American Journal of Ophthalmology
    |October 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Choroidal ischemia, a condition affecting blood flow in the eye, may be more common than previously thought. This finding is based on a study of patients with vascular disease but normal-appearing fundus examinations.

    Area of Science:

    • Ophthalmology
    • Vascular Biology
    • Medical Imaging

    Background:

    • Generalized vascular disease can affect various organ systems.
    • Choroidal perfusion is crucial for retinal health.
    • Retinal vascular changes are common indicators of vascular disease.

    Observation:

    • Nine patients (7 women, 2 men; age 21-86) with vascular disease presented with significant choroidal perfusion deficits.
    • Fundus examinations appeared normal, with no observable retinal vascular changes.
    • Abnormalities were detected exclusively through fluorescein angiography.

    Findings:

    • Significant deficits in choroidal perfusion were identified in patients with generalized vascular disease.
    • These perfusion abnormalities were not associated with visible retinal vascular changes.

  • Choroidal ischemia may be underdiagnosed due to normal fundus appearance.

    • Implications:

    • Choroidal ischemia might be a more prevalent condition than currently recognized.
    • Fluorescein angiography is essential for diagnosing subtle choroidal perfusion deficits.
    • Understanding choroidal ischemia is vital for managing vascular disease complications.
