Figure 1. Bland Altman plots comparing CCT between SD-OCT and Scheimpflug-Placido topographer (A), OLCR and SD-OCT (B), OLCR and Scheimpflug-Placido topographer (C), USP and OLCR (D), USP and SD-OCT (E), and USP and Scheimpflug-Placido topographer (F). The 95% limits of agreement are shown with dashed lines, and the solid line represents the difference between these measurements.
