Figure 4.

Within-eye and within-subject correlation. Within-eye (A) and within-subject (B) correlation of RPE-BM peak reflectivity of patients with PXE and controls. Within-eye correlation is measured with horizontally and vertically orientated OCT scans. For within-eye correlation, there were 101 comparisons for patients with PXE and 36 comparisons for controls. For within-subject correlation, there were 29 pairs of observation in patients with PXE and 19 pairs of observation in controls. The diagonal line represents the perfect correlation. In the top-left corner, the Spearman correlation coefficients (ρ) are shown for patients with PXE (black) and controls (gray).
