Summary

The difficulty to measure blood flow in humans is connected with the necessity of using not invasive, reliable and reproducible techniques.

There is several quantitative approaches to study eye blood flow which do not answer all these specifications. The laser doppler velocimetry allows movement speed measures but not vessel diameter. Optical coherence tomography doppler allows a simultaneous diameter and speed of travel (movement) measures, but presents a limited spatial resolution and thereby not easily reproducible vessel diameter measures.

The investigators propose development of a technique allowing a simultaneous diameter and velocity measure of these vessels.
