Abstract

We used laser Doppler holography, a full-field imaging technique, to measure blood flow in the retina and choroid with an unmatched temporal resolution. We here report on the measurement of the flow waveforms in retinal arteries and veins after spatio-temporal filtering of the power Doppler. We demonstrate a full field mapping of the local resistivity index, and the possibility to perform unambiguous identification of retinal arteries and veins on the basis of their systolodiastolic variations. This work demonstrates the potential held by laser Doppler holography to study ocular hemodynamics in healthy and diseased eyes.
