Test/Retest reproducibility of color Doppler imaging assessment of blood flow velocity in orbital vessels.


PURPOSE The purpose of this study was to evaluate the test-retest reproducibility of measures of blood flow velocities using color Doppler imaging (CDI) in orbital arteries. PATIENTS AND METHODS Measures of peak systolic velocity, end-diastolic velocity, and resistive index were performed in a group of 15 normal tension glaucoma patients and in 15 healthy… (More)
