在光镜和电镜下动态观察兔眼后房型人工晶体囊袋内植入术后的人工晶体表面,发现明显的纤维蛋白膜、炎性细胞和色素沉着。纤维蛋白膜在术后第1天即已形成,第7天最明显,术后14天有所减少。并发现,前房内纤维蛋白渗出是纤维蛋白膜形成的基础,与人工晶体表面的巨噬细胞、纤维母细胞样细胞、巨细胞一起共同参与此膜的形成,并使之机化。纤维蛋白膜和炎性细胞以人工晶体边缘、光学部分与袢连接处和定位孔处为多。分析纤维蛋白膜形成的原因可能是人工晶体刺激、血-房水屏障破坏和免疫反应所致。
Under light microscope and electron microscope, the intraocular lens (IOL) was implanted into posterior chamber intraocular lens (IOL) in rabbit eyes and the obvious fibrin membrane, inflammatory cells and pigmentation were found. Fibrin membrane in the first day after surgery has been formed, the most obvious on the 7th day, 14 days after the decrease. And found that anterior chamber fibrin exudation is the basis of fibrin membrane formation, and artificial crystal surface of macrophages, fibroblast-like cells, giant cells together to participate in the formation of this membrane, and to make it. Fibrin membrane and inflammatory cells to the edge of the artificial crystal, the optical part and 袢 junction and positioning holes at more. Analysis of fibrin membrane formation may be caused by artificial lens stimulation, blood-aqueous barrier damage and immune response.
