Increased levels of VEGF-165, VEGF-A, the endothelial junction protein CD31 and the lymphatic marker D2-40 as well as elevated blood and lymphatic vessel counts in pterygium specimens compared to normal conjunctiva support the fact that lymphangiogenesis and angiogenesis are pivotal for the pathogenesis of pterygium [115]. This evidence concerns the gene VEGFA and pterygium.
