对8例10眼先天性青光眼手术切除的小梁标木,进行扫描电镜(SEM)和透射电镜(TEM)观察。结果表明。SEM显示小梁异常有2型:①分化不全,小梁柱变性扭曲、断离,网眼缺乏,排列紊乱。②房角部分区域有不连贯的膜样细胞群遮挡。TEM显示小梁柱轴心胶原纤维或明显增多或明显减少,前者杂有高和低两种电子密度物质沉淀,后者小梁水肿。被覆的内皮细胞变性,线粒体呈大泡样结构。 8 cases of 10 cases of congenital glaucoma trabecular surgery were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show. SEM showed trabecular abnormalities have type 2: ① incomplete differentiation, trabecular degeneration distorted, off, lack of mesh, arranged disorder. ② corner of the area some inconsistent membrane-like cell block. TEM showed trabecular or axial collagen fibers significantly increased or significantly reduced, the former miscellaneous high and low two kinds of electron density material precipitation, the latter trabecular edema. Coated endothelial cells degenerate, mitochondria showed a large bubble-like structure.
