Histology picture of the cornea, stained with hematoxylin and eosin, magnification ×200, on day 4 of uveitis. (a) Control (): cornea is lined with epithelium and endothelium; collagen fibers and keratocytes (specialized corneal fibroblasts) are visible; (b) placebo (): swelling and loosening of corneal collagen fibers, endothelial desquamation, partial destruction of Descemet’s membrane; epithelium is not changed; (c) SOD1 (): moderate loosening of the corneal collagen fibers, partial endothelial desquamation, cell infiltration is absent; (d) SOD1 nanozyme (): normal structure of the cornea.
