摘　　要：应用扫描电镜对老年性白内障晶体浅皮质纤维表面形态结构进行观察。结果显示晶体浅皮质纤维表面结构与正常人有很大差异。最明显的是纤维表面的突起出现肿胀、变形和排列紊乱现象。纤维表面的微嵴数量增多间距增宽,排列不规律。纤维平滑面的斑块状结构消失。上述异常改变,是影响晶体透明度的重要因素。The surface ultrastructure of superficial cortical fibers of senile cataractous human lenses was observed by using scanning electron microscope. The results displayed a significant difference in the surface ultrastructure of superficial cortical fibers of lenses between senile cataract and normal person. It was most significant that the processus on the surface of the fibers appeared swelling, the shape of which changed and the arrangement of which was out of order; that the number of microridges on the surface of the fibers increased, arrangement of which was disorder. The plaquelike structure on the smooth surface of the fibers disappeared. These abnomal changes described above were the important factors affecting the degeneration of the lens.
