眼表羊膜手术的羊膜固定方式

眼表碱烧伤、角膜溃疡等多种眼表疾病均可造成角膜、结膜的损伤和缺失，且常伴有角膜新生血管的形成，进而影响视觉功能。而羊膜具有使急性损伤的角膜或结膜缺损区迅速上皮化，抑制炎症、减少瘢痕形成等作用。因此在眼表重建及治疗角膜新生血管方面，羊膜已得到大量应用。但在术中如何固定羊膜十分关键。既保证黏附时间和覆盖面积，又保证操作便捷且刺激性小才能达到最佳治疗效果。本文即对羊膜遮盖术中羊膜的固定方式进行综述。

Methods of amniotic membrane fixation in ocular amniotic membrane surgeries

Various ocular surface disorders like alkali burns and corneal ulcers can all cause damage to the cornea and conjunctiva, and often induce corneal neovascularization(CNV)that affects the visual function. However, amniotic membranes(AM)can promote the rapid epithelization of acute injured corneas and conjunctiva defects, diminish scarring, and perform anti-inflammatory effect. Therefore, AM has been widely used in ocular surface reconstructions and treatment of CNV. But the key problem is how to fix the AM. Only ensuring the adhesive time and cover area with convenient operation and little stimulation can achieve the best curative effect. This article reviews the methods of AM fixation in AM patch technique.
