[Blood flow velocity in the ophthalmic artery measured using transbulbar Doppler sonography]

Blood-flow velocity in the ophthalmic artery was examined at different orbital depths by pulsed ultrasound (4 MHz). Blood-flow velocity was influenced by patient age and showed a decrease in the vicinity of the eye. Forty-one normal subjects had an average systolic and diastolic blood-flow velocity of 36.5 and 10.9 cm/s at a 36 mm depth.
