华南首例!江西14岁少年在广州移植“猪角膜”后复明

2016-03-09 08:33:16   南方网

角膜

角膜:就是我们俗称的“黑眼珠”,位于眼球的正前方,形似圆球体的一部分。角膜透明无血管,感觉神经非常丰富。角膜可以保证外界光线毫无障碍地通过,到达眼底,获得清晰的成像。

人工角膜:国外虽然已有以异质性材料如玻璃、硅胶等为原料研发制作的人工角膜,但这些人工角膜均为人造高分子化学材料制成,存在生物相容性、力学特性差,临床试验效果不佳,无法形成连续化上皮,不能与患者自体组织完全整合等缺点,病人排异反应明显。

生物工程角膜:2015年4月底,国家食品药品监督管理总局为“艾欣瞳”颁发医疗器械注册证书,标志角膜再生医学领域的重大突破。这是由我国科学家自主研发并拥有完整自主知识产权的生物工程角膜,标志着世界上第一个也是唯一一个完成临床试验的生物工程角膜的上市。

生物角膜

移植

板层移植,患者哪层角膜受损就移植哪个层级。“使用生物工程角膜也有着严格的适应症,比如患者是患有角膜内皮失代偿或者角膜内皮营养不良引起的角膜溃疡患者,需要全层移植的患者并不适合应用该技术。”

去细胞

去抗原

处理

通过脱细胞方法去除猪角膜的免疫原性,可以降低猪角膜移植的炎症反应和免疫排斥反应。即便如此,剩下的这部分材质,还需要经过钴60的放射性辐照予以严格消毒。必须确保一些动物源性的疾病(发生于猪的疾病),不会因为移植而感染到人。

猪角膜

供应

通过对猪、牛、羊、鸡、鸭、鹅等筛选后,发现猪的角膜参数和人比较接近,其携带的病毒不太容易传染给人类。相比人的角膜,猪角膜来源丰富,最重要的是它具有和人角膜基质相似的组织结构。为了保证猪角膜的供应,研究方还专门设立了养殖场,同时在猪的品种上也有要求。

角膜病患者可免费筛查

为推动生物工程角膜“艾欣瞳”在广东地区的使用,更好地为广东地区的广大眼盲患者带来福音,中国再生医学国际有限公司联合广东三嘉公益组织将开展“助力光明-角膜盲精准扶贫项目”。广东三嘉公益执行理事长付明先生表示,该项目将对贫困山区角膜病患者进行免费筛查,并首批捐赠10枚生物工程角膜(价值二十余万元),用于患有角膜盲的贫困患者,为中国政府实现“2020年消灭可避免盲,让人人享有看见的权利”提供了强有力保证,这也推进了医疗卫生领域惠及民生工作。同时也呼吁更多的社会组织及相关企业共同来参加活动,让中国数百万的角膜盲患者有望重见光明,为我国的眼盲患者提供更多的便利与支持。
