Sliding transplantation of auto-corneal limbus stem cell combined with mitomycin C for pterygium treatment

AIM: To evaluate the efficacy of sliding transplantation of auto-corneal limbus stem cell combined with mitomycin C(MMC)on pterygium treatment. METHODS: Totally, 79 patients(89 eyes)who received treatment at our hospital were selected. Eighty-nine eyes of 79 patients with pterygium were randomly divided into two groups: 40 patients(45 eyes)in group A underwent sliding limbal autograft transplantation with MMC and 39 patients(44 eyes)in group B underwent simple limbal autograft transplantation. Recurrence rate and complications were observed during the 12-month follow-up.RESULTS: One of 45 eyes(2%)of group A and six of 44 eyes(14%)in group B were recurrent with significant difference(P0.05).CONCLUSION: Sliding transplantation of auto-corneal limbus stem cell combined with MMC for pterygium had advantages of lower recurrence rate, rapid recovery and less complications.
