Penetrating corneal homografts in vascularized rabbit corneas are regularly rejected if skin from the corneal donor is grafted to the corneal recipient.^1-4 The delayed graft reaction and the similarity of the clinical picture in experimental and in human grafts point to a common immunological type of reaction.

Corneal vascularization is required for the experimental immune rejection of corneal homografts;^5-6 in its absence, even lamellar heterografts can remain clear indefinitely.^6-7 One of the problems found in clinical cases of corneal homotransplantation is how to prevent the late corneal graft rejection (or graft sickness) when the transplant has been done in a vascularized host. To a certain extent, corticosteroids can prevent or diminish the reaction,⁶ but in most cases, they fail to prevent opacification of the transplant.

The successful use of antimetabolites, especially 6-mercaptopurine (6-MP) and its derivative azathioprine, in preventing the rejection of highly vascularized organs such . . . [Full Text PDF of this Article]
