The effect of probucol in the treatment of diabetic retinopathy was investigated to analyze its impact on its hemodynamics, rheology and blood lipid. A total of 80 patients with diabetic retinopathy who were treated in the Ninth People's Hospital of Chongqing (Chongqing, China) from January 2015 to August 2016 were selected and divided into two groups by random number table, with 40 patients in each group. Control group was treated by conventional and intensive glycemic control and antihypertensive therapy, while observation group was orally administered with 0.375 g probucol twice a day on the basis of intensive therapy. Outpatient follow-up was performed to all the patients for 6 months, then, among the blood rheology, the changes in blood viscosity and erythrocyte aggregation indexes at different time points before and after intervention in the two groups were compared, mean blood flow velocities in renal artery, renal artery pulse indexes and renal artery resistance indexes at different time points were recorded, changes in blood lipid of the two groups before and after intervention were compared, and complication rates during the treatment were calculated. After intervention, the whole blood viscosity at high shear rate, whole blood viscosity at low shear rate and plasma viscosity in observation group were lower than those before intervention and lower than those in control group after intervention (P&lt;0.05); The erythrocyte aggregation indexes in observation group were obviously increased compared with those in control group at 1 week, 1 month and 6 months after intervention (P&lt;0.05). The mean blood flow velocities in renal artery in observation group were remarkably higher than those in control group at 1 week, 1 month and 6 months after intervention (P&lt;0.05), while the renal artery pulse indexes and resistance indexes in observation group were lower than those in control group in the same period (P&lt;0.05). In observation group, the levels of total cholesterol (TC), triglyeride (TG) and low density lipoprotein cholesterol (LDL-C) after intervention were decreased compared with those before intervention, while the level of high-density lipoprotein cholesterol (HDL-C) was increased. The levels of TC, TG and LDL-C in observation group were lower than those in control group after intervention, while the HDL-C level was higher (P&lt;0.05). During the treatment, the total incidence of phlebitis, chills, fever, rash and maculopapule in observation group was obviously lower than that in control group. Probucol can significantly improve the hemodynamic and rheological indexes and lower blood lipid in the body, and is an effective medicine for diabetic retinopathy.
