First experiences with HLA-matched corneal grafts in high risk cases

In highly vascularized corneas the number of graft failures caused by irreversible rejections is higher than in non-or slightly vascularized corneas. The importance of antigen compatibility is demonstrated, especially in these 'high risk' cases. Ten highly vascularized corneas were grafted with HLA-matched donor material; only one reversible rejection was seen in this group. Nine non-or slightly vascularized corneas were grafted with donor material chosen a random. Retrospective HLA matching was performed. Three irreversible rejections were seen in this group. The number of HLA incompatibilities was high.
