VEGFA and pterygium: The geometric means of the tear VEGF concentrations in pterygium patients with DE were 8.98 times (95% CI 3.81–21.20), 3.41 times (95% CI 1.09–10.69), and 5.20 times (95% CI 2.87–9.44) higher than those of the VEGF concentrations in HCs without DE (p < 0.001), HCs with DE (p = 0.031), and pterygium patients without DE (p < 0.001), respectively.
