Group classifications: I: RRD with no PVR; II: RRD with PVR grade A and B; III: RRD with PVR grade C. Significant difference using one way ANOVA test among all RRD subgroups (). RRD: rhegmatogenous retinal detachment; VEGF-A: vascular endothelial growth factor-A; PDGF-AA: platelet derived growth factor-AA; PVR: proliferative vitreoretinopathy.
