The mRNA levels were evaluated for 5 peptide growth factors: transforming growth factor (TGFB1), vascular endothelial growth factor (VEGFA), basic fibroblast growth factor (FGF2), epidermal growth factor (EGF) and insulin-like growth factor (IGF1) in pterygium and phenotypically normal conjunctiva by employing qRTPCR which detected significantly higher levels of expression of FGF2 and VEGFA in the former, compared with the latter. This evidence concerns the gene FGF2 and pterygium.
