Figure 4.

Boxplots depicting FD development from baseline up to 6 months postoperatively according to disease severity for patients with complete datasets only. Due to the small sample size, FD development for moderate glaucoma eyes is not displayed. p-values for the difference between baseline to individual follow-up time points are derived from Wilcoxon signed-rank tests. p-values ≤ 0.05 are highlighted in bold. Note that distances between the time intervals are not to scale. SCP = superficial capillary plexus, DCP = deep capillary plexus, RPC = radial peripapillary capillaries, n = number.
