[Study of blood flow velocity in the central retinal artery using pulsed Doppler sonography].
Using the method of pulsed-wave ultrasound-Doppler-Sonography (2 MHz-probe; sample volume 10 mm; variable invading depth by using a so-called "flow-pipe"; transmission range 10 mW/m2), the author demonstrates an objective, reproducible and exact clinical test to examine blood-circulation in central retinal artery. Because of the fact, that the angle of ultrasound is nearly zero-degrees to central retinal artery, accuracy of measurement flow velocity is nearly hundred percent. Method can be applied without problems by using intracranial Doppler-Sonography (ICD). It is less expensive than Duplex-Sonographie for instance.
