Abstract:
Objective To examine the concentrations of hepatocyte growth factor(HGF)and vascular endothelial growth factor (VEGF)in the patients with diabetic neovascular glaucoma(NVG),proliferative retinopathy without neovascularization of the iris(PDR) and idiopathic macular role(IMH),and to determine the relationship between HGF and VEGF.Design Prospective case series. Participants 14 patients(14 eyes)with NVG,22 patients(22 eyes)with non-NVI PDR,19 patients(19 eyes)with IMH.Methods The double-antibody sandwich enzyme-linked immunosorbent assay(ELISA)was used to measure the intravitreous level of HGF and VEGF.Main Outcome Measures The concentrations of HGF and VEGF in the same specimens.Results The concentrations of HGF (mean?SD)in vitreous of NVG group,PDR group and IMH group were(12908.42?2946.46)、(9770.86?3802.99)、(4160.54?2044.80)pg/ ml,respectively(Kruskal-Walls test,X~2=32.36,P=0.000).In addition,significant differences were observed between groups of the concentrations of HGF(P＜0.01,respectively).The intravitreous concentrations of VEGF(mean?SD)in three groups were(823.50?718.58)、(821.82?786.27)、(22.73?3.20)pg/ml(X~2=28.30,P=0.O00),respectively(Kruskal-Walls test,X~2=32.36,P=0.000).There was no significant correlation between the concentrations of HGF and those of VEGF in the same specimens from each group(P＞0.05, respectively).Conclusions The intravitreous concentrations of HGF in the patients with diabetic NVG are obviously higher than those with IMH and non-NVI PDR,suggesting that HGF appears to be associated with mediating the neovascularization of retina and iris in NVG.However,it is not found there is any relationship between the intravitreous levels of HGF and VEGF.
