The correlation coefficient between rim area and cpRNFLT at different reference plane heights and with different disc types. (Pearson’s product/moment correlation coefficient) The highest correlations were found at a height of 120 μm in the FI group (r = 0.511, P = 0.006), 150 μm in the MY group (r = 0.575, P = 0.007), 180 μm in the SS group (r = 0.551, P = 0.017), and 60 μm in the GE group (r = 0.805, P < 0.001).
