Popis: Doppler ultrasound and supraorbital photoplethysmography were used to screen 79 patients undergoing 87 carotid endarterectomies in the perioperative period. Supraorbital photoplethysmography permitted continual monitoring of ophthalmic artery flow dynamics throughout the operation on 14 patients. The ratio of supraorbital pulse amplitude during and prior to carotid clamping correlated well with the carotid back (stump) pressure (R = 0.87, P
