Summary

The outstanding clinical picture of the early graft reaction is given by the rejection of the endothelium, which is caused by lymphocytes. These cells reach the graft via the scar and unhealed Descemet's membrane or the uveal tissue. Typical clinical pictures can be observed and correlated with various stages of the rejection of experimental grafts.

Abnormal wound healing, vascularization of the cornea, adhesion of the iris to the scar and chronic inflammation facilitate rejection. Endothelial regeneration is possible in eyes with normal host endothelium but the prognosis is bad in eyes with dystrophic endothelium which cannot replace destroyed graft endothelium. Retrograft membranes or abnormal endothelial cells are frequent findings in the late stages of graft rejection.
