Figure 2. Analysis of degrees of inflammation after BAC treatment. A: Increased corneal inflammatory index after BAC treatment. TNF-α expression was elevated in both the cornea and conjunctiva (B). Representative images showed more inflammatory infiltration in peripheral corneal stroma after BAC-treatment (D) compared with that of the control (C). In central cornea, fewer layers of epithelium and more epithelial damage in BAC-treated eyes (F) were observed than that of the control (E). Scale bar=100 μm.
