Histological observations of eyeballs at d21pi. H&E sections showed normal structures of posterior segment of the eyeballs in non-induced animals with different treatments (A–D). Infiltrating cells (arrow heads), vasculitis (arrow), and retinal folds (asterisks) were observed in EAU + Water group (E). Retinal fold (asterisk) was found in EAU + Dex group (F). Mild cell infiltration (arrow heads) was observed in EAU + lGTE group (G). No detectable change in posterior segment was observed in EAU animals treated with hGTE (H).
