Figure 1. Rejection kinetics of corneal allografts in the BN-PVG strain combination. A: An example of a well healed corneal allograft approximately day 21. B: Typical appearance of a rejected PVG allograft, arrow indicates epithelial rejection line (occasionally observed). C: Rejection kinetics of the BN-PVG strain combination BN-PVG n=15, BN-BN n=9.
