本文报道了波长488nm的氩光对兔及猴眼视网膜损伤的实验研究结果;求得氩激光通过前置镜及平行光后的ED_(50)值;并测定出在这两种照射光束条件下的角膜及视网膜上的光斑直径. In this paper, the experimental results of retinal damage in rabbit and monkey eyes at 488nm wavelength were reported. The ED50 value of argon laser passing through the frontal mirror and the parallel light was obtained. Under these two irradiation conditions, The cornea and retinal spot diameter.
