Correlation of serum leucine-rich α-2 glycoprotein 1 and fibroblast growth factor 21 levels with neovascular glaucoma
·AIM:To investigate the correlation of serum leucine-rich α-2 glycoprotein 1(LRG1)and fibroblast growth factor 21(FGF-21)levels with neovascular glaucoma(NVG).·METHODS:A total of 110 cases(110 eyes)with NVG admitted to the ophthalmology department from September 2020 to September 2022 were selected as NVG group,with 23 cases of grade Ⅱ,44 cases of grade Ⅲ,and 43 cases of grade Ⅳ,while 90 sex and age matched cataract patients(90 eyes)were selected as control group.The levels of LRG1,FGF-21,vascular endothelial growth factor(VEGF),pigment epithelium-derived factor(PEDF),and tumor necrosis factor-α(TNF-α)in serum were detected by ELISA;Pearson correlation analysis was used to analyze the correlation of serum LRG1 and FGF-21 levels with Teich grade,VEGF.PEDF and TNF-α levels.·RESULTS:The levels of serum LRG1,FGF-21,VEGF,PEDF and TNF-α in the NVG group were significantly higher than those in the control group(all P＜0.01).With the increase of Teich grading,the levels of serum LRG1,FGF-21,VEGF,PEDF and TNF-α in NVG patients significantly increased in turn(all P＜0.05).Correlation analysis showed that the levels of LRG1 and FGF-21 in serum of NVG patients were positively correlated with the levels of VEGF,PEDF and TNF-α(all P＜0.05).·CONCLUSION:The levels of LRG1 and FGF-21 in serum of patients with NVG are obviously increased,which are positively correlated with the levels of VEGF,PEDF and TNF-α,both of which may be related to the development of NVG.
