VEGFA and retinopathy of prematurity: Significant elevation and activation of MMP9 (p = 0.038), CFH (p = 2.24 × 10−5), C3 (p = 0.05), C4 (p = 0.001), IL-1ra (p = 0.0019), vascular endothelial growth factor (VEGF) (p = 0.0027), and G-CSF (p = 0.0099) proteins were observed in the vitreous of ROP babies suggesting an increased inflammation under hypoxic condition.
