Abstract

Described is a device for examining the eye using an ultrasonic probe, the device being designed to measure and record, reliably and reproducibly, all the main eye blood-circulation parameters. To this end, a mounting (1) is placed on the eye, the side of the mounting facing the eye having a concave recess which matches the curvature of the eyeball. Fitted inside the mounting (1) is a measurement probe (2) which is designed as a transceiver for pulsed signals and which includes both a pulse generator and a processing circuit suitable for measuring the Doppler effect.
