Fig. 2

Bland-Altman plots illustrating the agreement between (a) FAZA corrected with ALest vs. FAZA corrected with ALact and (b) FAZA before correction vs. FAZA after correction with ALact. Plots of relative change between (c) FAZA after correction with ALest vs. FAZA after correction with ALact, and (d) FAZA before correction vs. FAZA after correction with ALact. The linear dashed lines in (c) and (d) are linear fits to the data. The horizontal dashed lines in c and d indicate a 5% relative change in the FAZA. The yellow regions in a and b represent the 95% CI. ALact, actual axial length; ALest, estimated axial length; CI, confidence interval; FAZA, foveal avascular zone area; SD, standard deviation
