Abstract

Aim-To correlate peripapillary capillary perfusion parameters with structural &functional changes in mild,moderate,severe POAG.Methods-Cross sectional study of 100 pts 25 in each grp. HFA,OCT, OCT-A done. MD,PSD,RNFL thickness, vessel density and flux index calculated. Results- Average vessel density showed positive correlation with MD (Mild, r =0.41 p= 0.040,Moderate r =0.40,p= 0.046,SeverePOAG r =0.64 p=0.001)& negative correlation with PSD(Mild, r=-0.60,p=0.002,Moderate r=-0.55,p =0.005,SeverePOAG r=-0.64 p=0.001).Average flux index showed positive correlation with MD(Mild, r=0.45,p=0.024,Moderate r =0.42,p =0.037,Severe POAG r= 0.75,p <0.001)& negative correlation with PSD(Mild r=-0.56,P=0.003,Moderate r= -0.58,p= 0.002,Severe POAG r=-0.76 p <0.001).RNFL thickness showed positive correlation with average vessel density& average flux index. Conclusion- There was a spatial correlation of OCT-A parameters with the RNFL thickness parameters and visual function in glaucomatous eyes.
