Table 5

VEGF-A and PDGF-AA level ratio in each RRD subgroup.

Variable	Groups	n	Level (pg/ml)
VEGF-A/PDGF-AA vitreous	I	4	1.29 ± 0.19	0.0001
	II	4	0.35 ± 0.03
	III	9	0.78 ± 0.06
VEGF-A/PDGF-AA serum	I	4	0.95 ± 0.39	0.943
	II	4	1.03 ± 0.13
	III	9	0.96 ± 0.43

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.
