Alterations of corneal structures and goblet cells in the conjunctiva. (a, b) HE staining of corneal epithelium and goblet cells in the conjunctiva observed by PAS staining. Scale bars: 50 μm. (c) Decreased epithelial corneal layers were recorded after PDTC treatment (B + P vs. B + S: , day 28 vs. day 0: ). (d) Number of goblet cells decreased over time (day 28 vs. day 0: ). Compared to the B + S group, PAS staining showed markedly increased goblet cells in the B + P group (B + P vs. B + S: ).
