    Age-related changes slow blood flow in the choroid and cilioretinal arteries. This study analyzed fluorescein angiograms to understand how circulatory patterns in the eye change with age.

    Area of Science:

    • Ophthalmology
    • Vascular Biology
    • Gerontology

    Background:

    • The cilioretinal artery supplies blood to the optic nerve head, crucial for vision.
    • Age-related vascular changes can impact ocular circulation and optic nerve health.

    Purpose of the Study:

    • To investigate age-related alterations in ocular blood flow dynamics.
    • To compare the filling patterns of the central retinal artery, cilioretinal artery, and choroid in different age groups.

    Main Methods:

    • Analysis of rapid-sequence fluorescein angiograms from 127 healthy eyes.
    • Assessment of dye entry timing into the central retinal artery, cilioretinal artery, and choroid.
    • Stratification of participants into younger (≤49 years) and older (≥50 years) cohorts.

    Main Results:

    • In younger individuals, the cilioretinal artery filled simultaneously or prior to the central retinal artery.
    • In older individuals, the cilioretinal artery predominantly filled after the central retinal artery.
    • Comparison with choroidal filling revealed similar age-related slowing of circulation in both choroidal and cilioretinal arteries.

    Conclusions:

    • Ocular vascular circulation, particularly in the choroid and cilioretinal arteries, demonstrably slows with advancing age.
    • Sclerotic changes, more pronounced in choroidal vessels, contribute to this age-related circulatory decline.
    • Understanding these vascular changes is vital for comprehending age-related optic nerve head diseases.
