Figure 3. The protein levels of five inflammatory factors in patient tears were measured before and after the conjunctival autografting pterygium surgery. The protein levels of (A) HGF, (B) MMP2, (C) TGF-β1, (D) TNF-α, and (E) FGF2 were measured with enzyme-linked immunosorbent assay (ELISA) in the tears of patients in the suture group (n = 28) and the glue group (n = 28) before surgery and at postoperative day 1, 7, and 30. Each experiment was repeated three times. The data were presented as the mean ± standard error of the mean (SEM). * p<0.05.
