Histopathologic evaluation of blebs. HE staining of eye tissue revealed dense cells and fibrotic scarring in the control group (a,b) and relatively sparse cells and milder scar formation in the treatment group (c,d). EVG staining revealed dense collagen deposition and scar formation in the conjunctiva and sclera of the control group (e,f), whereas collagen deposition was faintly stained, conjunctival tissue was loose, and the subconjunctival space was maintained in the treatment group (g,h). Magnification: ×4 for (a,c,e,g); ×10 for (b,d,f,h). Arrows: the conjunctiva, arrow heads: the sclera.
