Abstract:
Objective To explore the impact of the interaction between fasting plasma glucose(FPG)and serum uric acid(SUA)on peripheral diabetic retinopathy(DR).Methods Peripheral DR patients(n=188)admitted to our hospital from July 2022 to June 2023 were selected as the research subjects and divided into mild to moderate non-proliferative diabetic retinopathy(NPDR)group(M-NPDR,n=114)and severe NPDR(S-NPDR,n=74)group.DM patients without diabetic retinopathy admitted to our hospital during the same period were set as the control(T2DM,n=100)group.The general data and biochemical indicators were compared among the three groups.Logistic regression was used to analyze the relationship between FPG and SUA and the severity of DR.The interaction between FPG and SUA was evaluated.A nomogram model was established to predict the occurrence of severe NPDR.Results The DM duration,best corrected visual acuity converted to logarithm of minimum resolution angles(logMAR BCVA),FPG,SUA and urinary albumin/creatinine ratio(UACR)in M-NPDR and S-NPDR groups were higher than those in T2DM group(P＜0.05).Subfoveal choroidal thickness(SFCT),albumin(ALB)and free triiodothyronine(FT3)were lower than those in the T2DM group(P＜0.05).BUN in S-NPDR group was higher than that in T2DM group(P＜0.05).The DM duration,logMAR BCVA,FPG,TC,TG and SUA in S-NPDR group were higher than those in M-NPDR group(P＜0.05),and SFCT was lower than that in M-NPDR group(P＜0.05).SFCT,FPG,ALB,SUA,and(UACR)were independent influencing factors of severe NPDR(P＜0.05).The column chart model predicted the probability of severe NPDR occurrence,with area under curve of 0.919 and 0.910 before and after validation,and the average absolute error of the calibration curve 0.013,which can be used as risk tool to predict DR severity of T2DM patients.Conclusions FPG and SUA are risk factors affecting the severity of DR and there is an interaction.Early warning of risk factors based on the nomogram model is helpful to improve the prognosis of patients with peripheral DR.
