Fig. 2. The relative density, presented as the average amount of each cytokine expressed in each dry eye syndrome (DES) severity grade group relative to that in the normal control group. (A-C) The areas of basic fibroblast growth factor (bFGF) (A), interleukin (IL)-10 (B), and transforming growth factor (TGF)-β2 (C) were significantly greater than those of normal controls only in grade 4 DES patients. (D) There was no significant difference of tumor necrosis factor (TNF)-α expression according to the grades of DES. (E) The areas of angiogenin in DES grade 3 and 4 patients were significantly lower than those of normal controls and DES patients of grades 1 and 2 (*p < 0.05).
