Figure 6.

The ΔG value (change in global cpRNFL thickness [follow-up – baseline]) for each of the 150 eyes. The x-axis represents the ΔG value, with the eyes displaced along the y-axis for visualization purposes. The vertical dashed lines represent the ΔG criteria of −3 to −8 um. The red circles are the eyes in the P group based on the RS; the green circles, the eyes in the NP group; and the gray circles, the eyes in the “uncertain” group, that is, neither P or NP. The gray arrows indicate the outliers in the uncertain group with the extreme ΔG value.
