重视角膜缘干细胞移植术后效果的合理评价

The importance of therapeutic evaluation on limbal stem cells transplantation

各种原因破坏角膜缘干细胞将导致角膜上皮缺损、新生血管长入、角膜结膜化等角膜缘干细胞衰竭。角膜缘干细胞移植是一种可供选择的方法。但是，由于此手术方式、移植条件不同，术后评价指标差异很大，因此，各种角膜缘干细胞移植术后的效果缺乏可比性，应制定移植术后合理的评价方法。

Damage to the limbus by disease or injury would result in corneal epithelium defects, neovascularization and conjunctivalization, which is called limbal stem cells deficiency and could be treated by limbal stem cells transplantation. But the outcomes of surgery were much different due to various surgical techniques, different grade damages of recipient site and criteria for clinical evaluation after surgery. This article focused on reasonable evaluation methodology after limbal stem cells transplantation.
