Abstract：
This case report aims to describe a modified continuous suturing technique for firm fixation of a human amniotic membrane graft in a patient with persistent epithelial defect (PED) after a chemical eye injury. As a result of this technique, the amniotic membrane (AM) was firmly fixed to the corneal surface with eight continuous and locked episcleral sutures that resembled an octagon graft. This technique was performed in a 14-year-old patient with PED after a chemical corneal burn. Three weeks after the surgery, the PED was completely healed. This simple continuous suturing technique can allow firm and stable fixation of AM grafts on the ocular surface in cases of PED after chemical burn. It may prevent early loss of the graft and facilitate corneal epithelial wound healing.
摘要：
此病例报告旨在描述一种改良的连续缝合技术，用于在化学眼损伤后患有持续性上皮缺损（PED）的患者中牢固固定人羊膜移植物。由于这项技术，羊膜（AM）牢固地固定在角膜表面，有八个连续和锁定的巩膜缝线，类似于八边形移植物。该技术是在化学角膜烧伤后的14岁PED患者中进行的。手术三周后,PED完全痊愈了.在化学烧伤后发生PED的情况下，这种简单的连续缝合技术可以使AM移植物牢固稳定地固定在眼表上。它可以防止移植物的早期丢失并促进角膜上皮伤口愈合。
