Figure 4. Dispase-injected mice developed cardinal features of proliferative vitreoretinopathy (PVR). A: Ocular fundi of dispase-injected eye and saline-injected control eye. Arrow shows PVR membranes. B: Hematoxylin and eosin (H&E) staining of dispase-injected PVR eye and saline-injected control eye. Arrow shows proliferative epiretinal membranes (EM). C: PVR percentages at 1, 2, 4, 6, and 8-week time points after dispase injection.
