title: Estimation of blood flow in the carotid artery and intraorbital ophthalmic artery by color pulse Doppler ultrasonography.
abstract: Blood flow velocity was estimated in the orbital part of the ophthalmic artery and in the carotid artery, by way of pulse Doppler ultrasonography. The equipment was a Toshiba SSA-270A machine. The material comprised 12 glaucoma patients (20 eyes, all with open angles) under satisfactory IOP control, mean age 52 years, and 28 healthy controls (mean age 40 years; 54 eyes). Systolic flow velocities of 46 cm/sec and 103 cm/sec, in the ophthalmic and carotid artery respectively, were found in the normal subjects. With mean values of 42 and 116 cm/sec in the glaucoma group there was no significant difference between groups. The same applied to the average flow velocities. A considerable interindividual variation was found.
