目的本文旨在探讨新鲜羊膜对复发性翼状胬肉的治疗中促进角膜愈合的作用,分析翼状胬肉手术失败的原因。方法选用翼状胬肉切除、自体结膜干细胞移植、新鲜羊膜遮盖角膜创面的手术,治疗复发性翼状胬肉。结果 71例72眼均获手术成功,随访12~24个月无复发。结论对翼状胬肉成因的正确认知、良好的显微镜的直视效果、熟练规范的显微手术技巧,是开展翼状胬肉手术治疗的基本要素;术中彻底清除瘢痕和血管组织、对活动性出血需充分止血、保证结膜和羊膜植床的光滑、结膜及羊膜与角膜缘或结膜必须紧密缝合固定,是手术成功的关键。
Objective To investigate the role of fresh amniotic membrane in promoting corneal healing in the treatment of recurrent pterygium and to analyze the causes of the failure of pterygium surgery. Methods Pterygium resection, autologous conjunctival stem cell transplantation, fresh amniotic membrane covering corneal wound surgery, the treatment of recurrent pterygium. Results Seventy-two eyes of 71 patients were successfully operated. No recurrence was observed in 12 to 24 months. Conclusions The correct understanding of the causes of pterygium, good looking at the microscope and proficient normative microsurgical skills are the basic elements for the surgical treatment of pterygium. The scars and blood vessels are completely removed during operation, Hemorrhage to be fully hemostatic, to ensure that the conjunctiva and amniotic plaque bed smooth, conjunctiva and amniotic membrane and limbal or conjunctival suture must be closely fixed, is the key to successful surgery.
