The objective was to investigate the clinical course of ocular damage and the healing process in eyes exposed to 162 GHz millimeter wave (MMW). As a 162-GHz electromagnetic wave source, a gyrotron FU CW GV was used. An ocular damaged rabbit model with good reproducibility for 162 GHz MMW exposure was developed, and damage occurrence threshold values were obtained. The right eyes of pigmented rabbits were exposed to 162 GHz from a spot-focus-type lens antenna, and the non-exposed contralateral eyes were used as control eyes. Slit-lamp examination 1 day after MMW exposure revealed a round area of opacity, characterized by fluorescein staining indicating damaged epithelial cells in the central pupillary zone. Corneal edema, indicative of corneal stromal damage, peaked 2–3 days after exposure, with thickness gradually subsiding to normal by 9 days after exposure. Power densities of 162 GHz MMW causing ocular damage with probabilities of 10, 50, and 90% obtained by probit analysis were 173, 252, and 368 mW/cm², respectively.

高频毫米波（162 GHz）引起的眼外伤的临床病程和损伤阈值的研究

目的是研究暴露于162 GHz毫米波（MMW）的眼睛的眼部损伤的临床过程和愈合过程。作为162 GHz电磁波源，使用了回旋加速器FU CW GV。建立了对162 GHz MMW暴露具有良好再现性的眼损伤兔模型，并获得了损伤发生阈值。从点聚焦型透镜天线将有色兔子的右眼暴露于162 GHz，将未暴露的对侧眼用作对照眼。MMW暴露后1天的裂隙灯检查显示出一个不透明的圆形区域，其特征是荧光素染色表明中央瞳孔区的上皮细胞受损。角膜水肿表明角膜基质受损，在接触后2至3天达到峰值，暴露后9天厚度逐渐恢复正常。通过概率分析获得的162 GHz MMW引起眼损伤的功率密度分别为173、252和368 mW / cm，概率分别为10％，50％和90％^2个。
