Rhesus monkeys' eyes were irradiated at 9.31 and 2.45 GHz at an average power density of 150 mW/cm^2. Up to the time of reporting, the authors state that microwave radiation had not resulted in deleterious ocular effects.

Abstract

Microwave irradiation of rhesus monkeys' eyes at 9.31 and 2.45 GHz and at an average power density of 150 mW per centimeter square is reported. Irradiation, beginning in 1976, of 17 monkeys (Macaca mulatta) was accomplished without restraint or anesthesia by training the monkeys to irradiate themselves. To data microwave radiation of these monkeys has not resulted in deleterious ocular effects.
