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.
