Figure 2

Corneal opacity induced by alkali burn is suppressed in NLRP3 KO mice cornea. Representative photographs are shown. Compared with WT mice (a, opacification grade 4; intense stromal opacity, only outline of pupil is visible), the opacification is suppressed in NLRP3 KO mice (b, opacification grade 2; minimal to moderate opacity including corneal stroma). Using opacification grade, it is shown that corneal opacity in NLRP3 KO mice (b) is significantly diminished compared with WT mice (a) (N = 10 each, WT mice; 3.5 ± 0.5, NLRP3 KO mice; 2.0 ± 1.2, *P < 0.05, MannWhitney U-test) on day 7 after alkali burn injury (c).
