Using the principle of promoting blood circulation to remove stasis to observe central retinal arterial and venous blood flow indexes

and hemorrheology of diabetic retinopathy patients with puerarin. Thirty patients with diabetic retinopathy were randomly divided into the treated group (n= 15) and the control group (n= 15). The treated group was given puerarin 400 mg per day intravenously dripping. The control group was given Mikebao 500 μg intramuscularly

once per day. Both groups were treated for 3 consecutive weeks as one treatment course. Two courses later

hemorrheologic parameters

central retinal arterial and venous blood flow indexes were observed. Comparison before and after treatment showed red blood cell aggregation index

the whole blood viscosity rate

plasma viscosity rate

fibrinogen and erythrocyte sedimentation rate

have all improved obviously (P<0.05

P<0.01). Compared with the control group

there was significant difference (P<0.05

P<0.01). With the treated group before and after treatment

the peak systolic velocity (PSV) of central retinal artery

their end diastolic volume

the acceleration

the central retinal venous reflux velocity have improved respectively. Naked eye visions were also improved

compared with the control group

the difference was significant (P<0.01). Puerarin could reduce blood viscosity

improve microcirculation

and play a positive therapeutic role in diabetic retinopathy.
