目的探讨撕剥角膜面翼状胬肉联合角膜缘干细胞移植术治疗翼状胬肉的临床效果。方法在显微镜下撕剥角膜面翼状胬肉联合角膜缘干细胞移植术治疗翼状胬肉50例(55眼),术后随访3~24个月。观察术后创面修复、胬肉复发以及移植片存活等情况。结果随访期内5眼复发(约占9%)。该术后角膜创面平整,修复较快,移植片存活良好,复发率较低。结论行撕剥角膜面翼状胬肉联合角膜缘干细胞移植术治疗翼状胬肉利于角膜缘干细胞功能和眼表的重建,可以明显地降低翼状胬肉术后复发率。
Objective To investigate the clinical effect of corneal pterygium conjunctival limbal stem cell transplantation in the treatment of pterygium. Methods Fifty cases (55 eyes) of pterygium were treated with corneal pterygium and limbal stem cell transplantation under microscope. The patients were followed up for 3 to 24 months. Postoperative wound repair, pterygium recurrence and graft survival were observed. Results During the follow-up period, 5 eyes recurred (about 9%). The postoperative corneal wound formation, repair faster, graft survival, low recurrence rate. Conclusions Tear corneal pterygium combined with limbal stem cell transplantation for the treatment of limbal stem cell function and limbal stem cell reconstruction of limbal stem cells can significantly reduce the recurrence rate of pterygium surgery.
