Abstract:
Objective To explore the variation characteristics of ganglion cell complex(GCC)parameters in patients with diabetic retinopathy(DR)at different stages and their relationship with hemoglobin(HB)level.Methods A total of 97 DR patients who were treated in our hospital from January 2021 to January 2023 were selected and divided into the moderate non-proliferative DR(mNPDR)group(n=35),the severe non-proliferative DR(sNPDR)group(n=32),and the proliferative DR(PDR)group(n=30).The general data,biochemical indicators,and GCC parameters of the three groups were compared.Logistic regression was used to analyze the influence of ganglion cell layer(GCL)parameters on the staging of DR.In addition,according to the terartiles of HB levels,they were divided into the low-level(LHB)group of(10.31±1.13)g/dl(n=32),the medium-level(MHB)group of(12.52±0.32)g/dl(n=31),and the high-level(HHB)group of(14.73±0.31)g/dl(n=34).The general data,biochemical indicators and GCC parameters of the three groups were compared,and the influence of HB on the stage of DR were analyzed by Logistic regression.Logistic regression was used to analyze the influence of HB level on GCC parameters.Results The age,hemoglobin A1c(HbA1c),fasting plasma glucose(FPG),total cholesterol,local lost volume of GCC(FLV),and overall lost volume of GCC(GLV)in the mNPDR,sNPDR,and PDR groups increased successively(P<0.05).Rate of anemia,low-density lipoprotein cholesterol in PDR group was higher than mNPDR and sNPDR groups(P<0.05).The HB,albumin,total bilirubin(TBIL),direct bilirubin(DBIL),thicknesses of GCC,retinal nerve fiber layer(RNFL),and ganglion cell layer(GCL)decreased successively(P<0.05).The TBIL,DBIL,GCC thickness,RNFL thickness and GCL thickness in the LHB,MHB and HHB groups increased successively(P<0.05),while the age,serum creatinine,FLV and GLV decreased successively(P<0.05).HbA1c,FPG,rate of anemia in the HHB group were lower than those in the LHB and MHB groups(P<0.05),and triglyceride in the MHB and HHB groups were higher than that in the LHB group(P<0.05).Logistic regression analysis showed that after adjusting for confounding factors,all GCL thicknesses and HB levels were influencing factors for DR staging.After adjusting for GCC and RNFL thicknesses,HB levels were influencing factors for the average thickness,minimum thickness,upper thickness,and lower thickness of GCL.Conclusions Both the thickness of GCL and the level of HB are factors affecting the DR staging.The level of HB has an impact on the thickness of GCL and deserves clinical attention.
