Abstrakt: Background: Since 1991 homologous penetrating limbokeratoplasty has been performed in 32 patients with severe limbal stem cell insufficiency following chemical/thermal burns. The long-term results considering the effects of HLA matching are presented for the first time.
Patients: All patients received systemic cyclosporin A and/or mycophenolate mofetil in the postoperative course. In 9 patients grafts with 0-1 HLA mismatches in the HLA A, B and DR loci, in 6 patients grafts with 2-6 mismatches and in 17 patients untyped grafts were used. Long-term clear graft survival was estimated according to Kaplan and Meier.
Results: Five years postoperatively, 50% of the grafts with 0-1 mismatches, 32% of the grafts with 2-6 mismatches and 18% of the untyped grafts were centrally clear (log-rank-test, p>0.05).
Conclusions: Although statistically not significant, HLA matched grafts seem to deliver better results than untyped grafts in penetrating limbokeratoplasty. Improvement of matching strategies and immunosuppression may possibly further improve current results.
