Objective To explore the relationship between changes in fasting blood glucose(FPG)and glycated hemo-globin(HbA1c)levels and the severity of vision in elderly patients with type 2 diabetic retinopathy.Methods 92 pa-tients with type 2 diabetes admitted to Quangang District Hospital in Quanzhou City from June 2020 to June 2022 were selected as the research subjects.According to the presence or absence of retinopathy,they were divided into a non-retinopathy group of 48 cases and a retinopathy group of 44 cases.According to the severity of visual impairment,the patients with retinopathy were divided into a mild group of 15 cases,a moderate group of 14 cases,and a severe group of 15 cases.All patients were tested for fasting blood glucose and visual acuity on the day after admission,and FPG and HbA1c levels among different groups were observed.Pearson correlation analyzed the relationship between changes in FPG and HbA1c levels and the severity of the patient's vision.Results The levels of FPG and HbA1c in the retinopathy group were significantly higher than those in the non-retinopathy group,and the differences were sta-tistically significant(both P<0.05).The FPG and HbA1c levels in the moderate to severe group were significantly higher than those in the mild group,and the severe group was higher than the moderate group,and the differences were statistically significant(both P<0.05).FPG,HbA1c were positively correlated with the degree of visual impair-ment in patients with diabetic retinopathy(r=0.436,0.531,both P<0.001).Conclusion FPG and HbA1c levels are positively correlated with the degree of visual impairment in elderly patients with type 2 diabetic retinopathy.
