  Laser Doppler holography was introduced as a full-field imaging technique to
measure blood flow in the retina and choroid with an as yet unrivaled temporal
resolution. We here investigate separating the different contributions to the
power Doppler signal in order to isolate the flow waveforms of vessels in the
posterior pole of the human eye. Distinct flow behaviors are found in retinal
arteries and veins with seemingly interrelated waveforms. 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. Finally we investigate the arterial flow waveforms
in the retina and choroid and find synchronous and similar waveforms, although
with a lower pulsatility in choroidal vessels. This work demonstrates the
potential held by laser Doppler holography to study ocular hemodynamics in
healthy and diseased eyes.
