No of patients with detectable vitreous PDGF concentrations (n= 31)
| Vitreoretinal pathology | Detectable | Undetectable |
|---|---|---|
| RD + PVR | 7 (mean 55.1 pg/ml) | 1 |
| RD | 0 | 10 |
| Vitreous haemorrhage | 8 (mean 73.3 pg/ml) | 0 |
| IOFB | 4 (mean 29 pg/ml) | 1 |
RD = retinal detachment; PVR = proliferative vitreoretinopathy.
↵Statistical analysis using the Wilcoxon rank sum test indicates that PDGF concentrations are significantly higher in patients with RD and PVR than in patients with RD alone at the α < 0.001 significance level.
