Average compound plane-wave images (A, B), and power Doppler images (C, D) of the ONH region obtained from two sets of data from a healthy 46-year-old female subject. Each set was acquired for 1.6 seconds at 6.66-KHz compound imaging frame rate (three angles over ±10° per image). After postprocessing with the plane-wave Doppler technique, choroidal perfusion and flow in the short posterior ciliary artery and central retinal vein are visualized.
