Abstract/OtherAbstract:
PURPOSE: To test the effects of clodronate liposomes on graft survival and neovascularisation after transplantation in pre-vascularised recipient corneas. METHODS: Corneal neovascularisation was induced in F344 rats by injecting heat inactivated rabbit serum intrastromally. After 4 weeks F344 rats were orthotopically grafted with corneal buttons from DA rats. Directly after transplantation and on 2, 4, 6 and 8 days postoperatively clodronate liposomes were administrated subconjunctivally in one group, whereas the other group remained untreated. For 60 days grafts were observed for signs of graft rejection and neovascularisation. RESULTS: Graft survival was significantly prolonged, but not prevented in clodronate liposome treated rats compared to untreated rats ( p =.004). Also clodronate liposome administration delays growth of corneal neovascularisation after transplantation. CONCLUSIONS: Previous studies revealed that clodronate liposomes prevent corneal graft rejection and reduce neovascularisation in orthotopic corneal allotransplantation in rats. This study shows that also in pre-vascularised recipient corneas subconjunctival administration of clodronate liposomes seems to delay corneal graft rejection and reduces neovascularisation.
