The expression levels of four factors in the tears of patients with fungal keratitis in the early stage are as follows: galectin-3, 36107.60 ± 6116.71 pg/mL (P < 0.05); IL-1β, 242.76 ± 105.73 pg/mL (P < 0.05); IL-18, 194.57 ± 29.45 pg/mL (P < 0.05); and TNF-α, 49.91 ± 17.57 pg/mL (P < 0.05) (Figure 1(c)) while galectin-3, 87507.08 ± 31474.39 pg/mL (P < 0.05); IL-1β, 1526.30 ± 766.98 pg/mL (P < 0.05); IL-18, 148.11 ± 28.99 pg/mL (P < 0.01); and TNF-α, 70.29 ± 27.73 pg/mL (P < 0.05) in the late stage (Figure 1(d)), respectively. The gene discussed is TNF; the disease is fungal keratitis.
