High-frequency Doppler ultrasound examination of blood flow in the anterior segment of the eye.


PURPOSE To show that extending Doppler imaging into the high-frequency domain could allow detection and characterization of blood flow in small arterioles and capillaries. METHODS A 40-MHz continuous wave Doppler system and a 60-MHz pulsed-wave Doppler system were constructed, tested, and used to examine the ciliary body region in two normal volunteers… (More)
