CA 2478091

Apparatus and method for the measurement of vascular impedance of the ocular circulation in vivo are provided. A pressure pulse waveform is recorded from measurement of the intraocular pressure, and the velocity profile of blood flow in the retrobulbar circulation is recorded. These two readings are used to calculate the vascular impedance modulus.

Cette invention a trait à une méthode, ainsi qu'à l'appareil correspondant, permettant de mesurer, in vivo, l'impédance vasculaire de la circulation oculaire. On enregistre une forme d'impulsion de pression, dérivée de la mesure de la pression intra-oculaire, ainsi que la vitesse de débit sanguin de la circulation rétrobulbaire. On utilise ces deux lectures pour calculer le module de l'impédance vasculaire.
