Abstract:To observe the changes of blood glucose, coagulation factors and platelet parametersin patients with diabetic retinopathy, and to explore their clinical significance in diabetic retinopathy. Methods A total of 102 patients with diabetic retinopathy were selected as diabetic retinopathy group, 102 patients with diabetes mellitus as diabetic group and 102 healthy subjects as control group from March 2014 to October 2016 in Haikou People's Hospital. The blood glucose, coagulation factors and platelet parameters were measured in the three groups. Results The diabetic duration in the diabetic retinopathy group was longer than that in the diabetic group (p < 0.05). The levels of FPG and HbA1c in the diabetic retinopathy group were higher than those in the diabetic group and the control group ( p< 0.05). The levels of FPG and HbA1c in the diabetic group were higher than those in the control group (p < 0.05). FIB and PT% of the diabetic retinopathy group and the diabetic group were higher than those of the control group ( p< 0.05). FIB of the diabetic retinopathy group was higher than hat of the diabetic group ( p< 0.05). The levels of P-LCR, MPV and PDW in the diabetic retinopathy group and the diabetic group were significantly higher than those in thecontrol group (p < 0.05). The levels of P-LCR, MPV and PDW in the diabetic retinopathy group were higher than those in the diabetic group (p < 0.05). Conclusions Blood glucose, coagulation factors and platelet parameters in patients with diabetic retinopathy are abnormal. The diabetic retinopathy may be associated with the changes of blood glucose, coagulation factors and platelet parameters.
