摘要
翼状胬肉是多发的常见病,关于其病理改变,光镜下所见有关专著中多已论及,但其超微结构的情况尚少研究。本文就我们观察的病例报道于后,以求教于同道。材料与方法1.病例:6例7眼,1例为双鼻侧复发性,5例5眼为单眼鼻侧进行性翼状胬肉。均可见帽头颈体尾各部,帽头部水肿,体部充血肥厚,血管增殖明显。2.制片:将手术切下之胬肉组织按帽、头、颈、体、尾5部分切开。
Ultrastructure of the pterygium have been studied with transmi-ssion electron microscopy in 7 eyes of 6cases. The pterygium wereadvanced type in 5eyes and recurrent in 2 eyes. All were in nasalside. The clinical feature were edema of the areas of the apex (cap),and congestion, neovascularization of the head areas. The specimenof every pterygium were distributed to 5 areas, Which included cap,head, neck, trunk and tail. TEM: There were many fibrillogenesis andneovascularization in the caps, capillary sprouts and immature capilla-ries in the heads, various differential vessels in the necks and trunks,and fibrogenesis or fibroplasia in the tail areas. The fibrogenesis andneovasularization of the advanced pterygium encroached the cornea andto destroy. The advanced change in clinic must be checked.
