HLA-compatible donor cornea for prevention of allograft reaction.
Our series comprises 80 penetrating grafts. Of the recipient corneas 36 were vascularized. Of the donor corneas 48 were fresh and 32 were cryopreserved. As prophylaxis, we gave topical and systemic prednisolone, combined, in heavily vascularized cases, with azathioprine. Corneal donor-recipient pairs were divided into three groups according to HLA histocompatibility. In Group I  (0-1 mismatch) the rate of allograft reaction was 1 in 27, in Group II (2-4 mismatches) it was 4 in 19, and in the untyped Group III 9 in 34. Even when the prognosis was poor, a well-matched donor cornea (Group I) greatly improved the chances of success; when the corneal bed was vascularized, the well-matched donor corneas had a failure rate of 1 in 13, whereas in untyped pairs it was 7 in 18. The importance of possible presensitization is discussed.
