Anesthetized rabbits were positioned on a styrofoam pedestal with the left eye on the axis of the beam, one foot beyond the second focal point of the dish antenna
No ocular changes could be found in animalsexposed for 15 or 30 min at power densities of 100 or 200 mW/cm2. Also no longterm effects under these exposure conditions could be observed by monthly examination for a one-year periode. At 300 mW/cm2 and above, acute effects, such as miosis, anterior chamber flare, injection of the conjunctiva, and dilations of irisvessels, were found. These effects persisted for as long as 24 h and were believed to be caused by thermalstress. One year after exposure these changes were absent.
