羊膜在结膜囊成形术中的临床应用

目的总结羊膜在结膜囊成形术中的应用及临床疗效。方法对24例不同眼部疾病患者行结膜囊成形术。其中11眼结膜缺损,行单纯羊膜移植术;5眼睑球粘连牵涉角膜或角膜有大量新生血管,行羊膜移植联合板层角膜移植术;8眼行羊膜移植联合结膜穹窿成形。术后随访6～12个月。结果无1例感染。10d后,移植的羊膜透明,缝合处结膜向羊膜上爬行;1个月后新生的结膜上皮完全覆盖移植区。24眼术后治愈9眼(37.5%),好转13眼(54.2%),无效2眼(8.3%)。结论羊膜是修补结膜囊的一种有效材料。

Application of Amniotic Membrane in Conjunctival Sac Plasty

Objective To observe the application of amniotic membrane in conjunctival sac plasty. Methods 24 cases with different eye diseases were performed with conjunctival sac plasty, in which 11 eyes were performed with amniotic membrane transplantation, 5 eyes with symblepharon which adhered with cornea or emerged neovascularization were performed with amniotic membrane transplantation and lamellar keratoplasty, other 8 eyes were performed with amniotic membrane transplantation and conjunctival fornixe. They were followed up for 6-12 months. Results There was no inflammation observed after operation. The transplanted amniotic membrane turned transparent and the conjunctiva at sewing location crawled to amnion 10 d after operation. One month later, the neonatal conjunctiva covered transplanting region completely. Among the 24 eyes, 9 eyes were healed, 13 eyes were improved, and 2 were ineffective. Conclusion Amniotic membrane is a kind of effective material during conjunctival sac plasty for narrow conjunctival sac.
