 Colour Doppler imaging results and blood pressure measurements of the three study groups

Control group(n = 40)Stable glaucoma(n = 102)Progressive glaucoma(n = 12)
CRA, central retinal artery; EDV, end-diastolic velocity; PSV, peak-systolic velocity; SPCA, short posterior ciliary artery.
*Significant differences between the groups (p<0.05).
