Bold values indicate statistical significance. Regarding VEGF-A level, in pairwise comparison with the control group, all intervention groups showed lower VEGF-A levels than the control group (p = 0.004 for subconjunctival bevacizumab vs. control, p = 0.010 for subconjuctival aflibercept vs control, p < 0.001 for intrastromal bevacizumab vs. control, and p < 0.001 for intrastromal aflibercept vs. control). Regarding VEGF-B level, in pairwise comparison with the control group, aflibercept groups showed lower VEGF-B levels than the control group (p = 1.000 for subconjunctival bevacizumab vs. control, p = 0.027 for subconjuctival aflibercept vs. control, p = 1.000 for intrastromal bevacizumab vs. control, and p = 0.002 for intrastromal aflibercept vs. control). Regarding PIGF level, in pairwise comparison with the control group, only the intrastromal aflibercept group showed lower PIGF levels than the control group (p = 1.000 for subconjunctival bevacizumab vs. control, p = 0.636 for subconjuctival aflibercept vs. control, p = 0.964 for intrastromal bevacizumab vs. control, and p = 0.031 for intrastromal aflibercept vs. control).
