The purpose of this review is to describe the most recent and relevant clinical and experimental data about the use of amniotic membrane in ophthalmology.
The amniotic membrane is a biologic tissue that has been used as a graft for corneal and conjunctival reconstruction in a variety of ocular surface diseases. It is avascular and possesses anti-angiogenetic, anti-scarring and antiinflammatory properties. It is not a substitute but rather a substrate upon which cells can migrate and regenerate, forming new and healthy tissue. The amniotic membrane can also be used as a biologic patch, as a bandage, to treat acute inflammatory disorders. With the development of cell therapy, amniotic membrane can be also used as a carrier of limbal stem cells or their progeny, cultivated in vitro.
Amniotic membrane use in ophthalmic surgery has been shown to provide an alternative for corneal and conjunctival reconstruction in many clinically challenging situations; however, there is still a lack of scientific evidence based on randomized comparative studies to prove that its use is better than other alternative therapies for ocular surface reconstruction.
本综述旨在描述关于羊膜在眼科应用的最新及相关临床和实验数据。
羊膜是一种生物组织,已被用作多种眼表疾病角膜和结膜重建的移植物。它无血管,具有抗血管生成、抗瘢痕形成和抗炎特性。它不是替代品,而是细胞可以迁移和再生、形成新的健康组织的基质。羊膜还可用作生物补片、绷带,以治疗急性炎症性疾病。随着细胞治疗的发展,羊膜还可作为体外培养的角膜缘干细胞或其后代的载体。
在许多具有临床挑战性的情况下,羊膜在眼科手术中的应用已被证明可为角膜和结膜重建提供一种替代方法;然而,仍然缺乏基于随机对照研究的科学证据来证明其应用比其他眼表重建替代疗法更好。
