Figure 2. Comparison of tear cytokine/chemokine levels in DED patients with control subjects. EGF, Fractalkine/CXC3L1, IL-1Ra, IP-10/CXCL10, and VEGF levels were significantly increased in evaporative-type DED tear samples compared to controls. Values are presented on a logarithmic scale. EGF, epidermal growth factor; IL, interleukin; IL-1Ra, interleukin 1 receptor antagonist; IP-10, interferon inducible protein 10; VEGF, vascular endothelial growth factor. OD, right eye; OS, left eye. *p<0.05, DED tears compared to corresponding controls.
