Research the Relations between HbA1C and the Thickness of Diabetic Retinopathy in the Macular Area

Objective: To research the relationship of retinal thickness at macular area and related biochemical indicators HbA1 C in early diabetic retinopathy patients. Methods: Diabetes group had 20 cases(40 eyes), male is 12 cases and female is 8 cases. The control group had 20 cases(40 eyes), male is 14 cases and female is 6 cases, optical coherence tomography(OCT) was applied to measuring the retinal thickness at macular area. including central macular thickness(CPT), thickness of macular central concave down(SCMT), macular volume(TMV). Related biochemical analyzer was used to test glycosylated hemoglobin(HbA1C) in the diabetes group. Two groups of retinal thickness at macular area were compared and the relationship of macular area thickness and related biochemical indicators in the diabetes group was analyzed. Results: Macular area in the selected diabetes group patients was thicker than that in normal group, which was positively correlated with HbA1C(P0.05). Conclusion: For patients with early diabetes, detecting the macular area thickness and HbA1 C changes is conductive to the early prediction of complications of diabetes.
