[Noninvasive functional exploration using photoreflexometry].

Photoreflexometry measures the filling time of the intradermic venous plexus and quantifies the function of the venous pump in the leg. Thus it completes the other methods of venous functional investigation and provides data-figures on the seriousness of post-phlebitic illness. The essential interest of the non-invasive examination is that it makes it possible to read the phlebographic and therapeutic indications more discerningly.
