Fig. 5

Correlation coefficients (ρ) by sector between SAP and mfPOP arcuate clusters, and RNFL sector thicknesses. Black shading represents zero or negative correlations; shading is lighter for higher correlations with white representing 100% correlation. Coefficients in bold/blue indicate the highest r of each subject classification for that sector across the different functional tests, i.e. across each row. Sectoral correlations were strongest in the superior superotemporal sector in patients with one eye classified Severe. The “n” reported below the subject subgroup titles represents the number of subjects in each subgroup. P-value degrees of freedom for Normal subjects and those with Mild, Moderate and Severe glaucoma are 46, 18, 10 and 16 respectively. (* p < 0.05, ** p < 0.01, *** p < 0.001). RNFL clock-hour sectors: S = superior, N = nasal, I = inferior, T = temporal
