目的探讨采用自体角膜缘部上皮移植（limbalautografttansplantation，LAT）治疗复发性翼状胬肉的临床效果和有效机制。方法采用LAT治疗58例（58眼）复发性翼状胬肉。结果除1眼再次复发，其余57眼均获满意效果。随访1年以上，未见胬肉样组织（结膜源性组织）长入角膜，视力也均有不同程度提高。结论自体角膜缘上皮移植治疗复发性翼状胬肉为受损的角膜缘提供了新的干细胞来源，是一种有推广意义的新术式。
Objective To investigate the clinical effect and effective mechanism of limbal autograft transplantation (LAT) on recurrent pterygium. Methods 58 cases (58 eyes) of recurrent pterygium were treated with LAT. The results in addition to a recurrence of the other eyes, the other 57 were satisfactory results. Follow-up more than 1 year, no pterygium tissue (conjunctival tissue) grew into the cornea, visual acuity also increased to varying degrees. Conclusion Autologous limbal epithelial transplantation for the treatment of recurrent pterygium provides a new source of stem cells for the damaged limbal limbus and is a promising new technique.
