In 1985, Kues et al. (Bioelectromagnetics, 6, pp.177-188, 1985) report
ed that corneal endothelial abnormalities were observed after a 4-hour
exposure of anesthetized monkey eyes to 2.45 GHz CW. We have traced t
heir experimental study without anesthetization. Although we irradiate
d with power density exceeding the threshold of 30 mW/cm2 obtained by
them, we could not observe the same abnormalities as they did.
