Abstract:
The purpose of this study was to determine the role of CDI in the assessment of normal ocular vasculature. Color and pulsed Doppler examinations were performed in 20 healthy subjects. The principal orbital vessels were detected: ophthalmic, central retinal, lacrimal, and posterior ciliary arteries and, in a small percentage, superior ophthalmic, central retinal, and vortex veins; blood flow of arterial vessels was studied by measuring TAV, St, PS, MD, ED, PI, and RI; the morphology of the spectral waveform also was investigated. Our results suggest that duplex color Doppler may be of value in ocular vasculature examination.
