Retinal color Doppler flow in control (a), diabetes (b), LBP-400 (c), and LBP-200 (d) groups. (a)–(d) Representative color Doppler image showing blood flow in the central retinal artery and central retinal vein (curve below 0 in Y-axis). (e) Measurements of peak systolic velocity (PSV), end-diastolic velocity (EDV), central retinal vein velocity (CRV), and mean flow velocity (MV). Diabetes decreased PSV, EDV, CRV,and MV. LBP treatment increased these velocity measurements compared with the diabetic control group. 0.05 compared with the control group; P<0.05 compared with the model group.
