Fig. 3 — Example of an eye with different disc centring between baseline (A) and follow-up (B) scans. The red arrows and dashed red lines confirm the misalignment by the position of the blood vessel shadows on the circle scan. A second example shows different foveal centreing (white crossed lines) in the baseline (C) and follow-up (D) RGC+ probability plots. The black arrows indicate areas with subtle differences in the probability values due to foveal centring rather than true glaucomatous progression.
