玻璃体手术中巩膜穿刺孔脱出物的组织病理学检查

Histopathologic examination of the prolapsed tissues at sclerotomy site during vitrectomy

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 2 0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。

Objective To investigate the histopathologic characteristic of the vitreous herniation out of sclerotomy site during vitrectomy. Methods Twenty specimens of tissues herniated at vitrectomy site were collected. The paraffin sections or fresh smears were stained with hematoxylineosin and examined under light microscope. The specimens were collected from the affected eyes with rhegmatogenous retinal detachment (9 cases), traumatic retinal detachment (1 case), miscellaneous vitreous hemorrhage (6 cases) and intraocular foreign body (4 cases). Results The herniated tissues were found to be retina in 4 cases, ciliary tissue in 1 case, retina and ciliary tissue in 1 case, uvea in 1 case,and hyaloid tissue in 13 cases. Conclusion There were not only vitreous, ciliary epithelial cells and pigment contained epithelia, but also ciliary body, retina and uvea in the prolapsed tissues of sclerotomy site, which might be related to the occurence of some clinical complications.
