    Laser Doppler Holography (LDH) is a non-invasive imaging technique that assesses choroidal blood flow with high temporal resolution.

  • 2

    LDH can differentiate between arterial and venous blood flow, providing quantitative hemodynamic data and visualizing flow waveforms.

  • 3

    The systematic review identified 10 studies, with a meta-analysis revealing a pooled mean diameter of choroidal arteries at 134.2 μm.

  • 4

    LDH offers advantages over traditional imaging methods by capturing rapid blood flow changes and providing full-field maps of the choroid.

  • 5

    This review aims to establish normative reference values for choroidal vascular anatomy and identify gaps for future research.
