[Tissue typing in perforating corneal transplantation].
The demand for matched corneal grafts has risen rapidly over the last years. One reason for this is the change in the judgement of the value of tissue and especially HLA typing for prevention of an immune reaction in perforating corneal transplantation. Besides HLA or major antigens, there are other immunologically relevant tissue surface molecules such as the non-MHC antigens of which blood groups and minor antigens are the most important. With regard to effective cost-benefit and waiting time-benefit analyses, differentiated matching strategies are needed to assure optimized utilization and allocation of the still unsatisfactory number of available corneal grafts. With special matching strategies, such as the calculation of the individual waiting time, the consideration of split, non-MHC and HLA antigens, additional HLA loci as well as so-called "permissible" and "taboo" mismatches, much more has to be taken into account in the future than just the numerical correspondence of HLA antigens. This will make it possible to turn from a pure numerical approach to a functional matching strategy. This review summarizes the discussion and different matching strategies, possibilities and limitations of HLA and tissue typing in perforating corneal transplantation.
