Bland–Altman plots showing the level of agreement between 3 × 3 mm (left column) and 6 × 6 mm scans (right column) for vascular density (a, b) and perfusion density (c, d) in the fovea and foveal avascular zone (e, f). The solid line denotes the mean difference, and the dashed lines denote the 95% confidence limits of agreement.
