Implication

May enable absolute retinal RBC velocity assessment; leaves open clinical validation before practice adoption.

Structured PICO

Does a bidirectional laser Doppler technique provide absolute measurement of red blood cell speed in retinal vessels?

P
Population
Retinal vessels (preliminary measurements using a prototype instrument)
I
Intervention
Bidirectional laser Doppler technique
O
Outcome
Absolute measurement of maximum red blood cell speed (V(max))surrogate

A novel bidirectional laser Doppler technique allows for absolute measurement of red blood cell speed in retinal vessels independent of vessel orientation.
