  The choroid is a highly vascularized tissues supplying the retinal pigment
epithelium and photoreceptors. Its implication in retinal diseases is gaining
increasing interest. However, investigating the anatomy and flow of the choroid
remains challenging. Here we show that laser Doppler holography provides high
contrast imaging of choroidal vessels in humans, with a spatial resolution
comparable to state of the art indocyanine green angiography and optical
coherence tomography. Additionally, laser Doppler holography contributes to
sort out choroidal arteries and veins by using a power Doppler spectral
analysis. We thus demonstrate the potential of laser Doppler holography to
improve our understanding of the anatomy and flow of the choroidal vascular
network.
