We studied light and electron microscopic findings in one case of cataract resulting from accidental radioisotope irradiation. A 53-year-old male, a radiographer, was irradiated by Ga-citrate which dropped accidentally into his left eye during a radioisotope procedure. Subsequently opacity appeared in the posterior and anterior subcapsular area of the left lens and increased in intensity. Intracapsular cataract extraction was performed one and a half years after the accident. The extracted lens was studied by light and transmission electron microscopy. Epithelial cells showed frequent stratification in some sites and disappeared in others in the equatorial region. Wedl cells and vacuoles were also seen in the posterior subcapsular area. Degeneration of lens fibers, including multilayered whorls, were observed in the cortex.
我们研究了1例因意外放射性同位素照射导致白内障的光镜和电镜检查结果。一名53岁男性放射技师在一次放射性同位素操作过程中，左眼意外被柠檬酸镓照射。随后，左眼晶状体后囊下和前囊下区域出现混浊，且混浊程度加重。事故发生一年半后进行了囊内白内障摘除术。对摘除的晶状体进行了光镜和透射电镜研究。赤道区上皮细胞在某些部位频繁分层，在其他部位消失。后囊下区域也可见韦德尔细胞和空泡。皮质中观察到晶状体纤维变性，包括多层螺旋状结构。
