Abstract： 目的研究玻璃体手术中巩膜穿刺孔脱出物的组织病理学表现.方法标准的睫状体平坦部三通道玻璃体手术中,用剪刀平巩膜面剪取巩膜穿刺孔脱出的眼内组织,石蜡包埋切片或涂在干净玻璃片上,苏木素-伊红染色,光学显微镜检查.共收集到20例标本,裂孔性视网膜脱离9例,外伤性视网膜脱离1例,各种原因的玻璃体积血6例,眼内异物4例. 结果巩膜穿刺孔脱出组织光学显微镜检查发现为视网膜4例,睫状体1例,视网膜和睫状体组织1例,葡萄膜组织1例,玻璃体组织13例.玻璃体组织内含有各种形态的细胞和含色素细胞及色素颗粒. 结论巩膜穿刺孔脱出物中既含有玻璃体、睫状体上皮和色素上皮细胞,也可有睫状体、视网膜和葡萄膜组织,这些嵌顿的细胞和组织可能与一些临床并发症的发生有关.
