Key result
Electrooptical laser Doppler accurately measures retinal blood speed, with arteries showing fewer artifacts than veins.
Why the study?
A technique for absolute measurement of red blood cell speed in retinal vessels was needed to improve assessment of retinal circulatory alterations.
The development of an electrooptical laser Doppler system enables absolute measurement of blood speed and flow rate in retinal vessels, which is useful for studying retinal circulatory alterations.

Supports absolute retinal RBC speed measurement; leaves open clinical validation before practice adoption.
Feke et al. (1987) studied Retinal vascular disease. Electrooptical laser Doppler system was evaluated on Absolute measurement of blood speed in retinal vessels. An electrooptical laser Doppler system provides absolute measurements of red blood cell speed in retinal vasculature, with retinal arteries being less susceptible to experimental artifacts than veins.
