Abstract :
The acute ocular injury threshold of 76 GHz band millimeter wave (MMW) exposure was investigated using an in vivo rabbit model. Pigmented rabbits were exposed unilaterally to 200, 100, 75, 50, 10 mW/cm2 76 GHz band MMW for 6 min with a lens antenna. Corneal opacity, epithelial injury, miosis, and ocular inflammation were present up to 2-3 days after exposure at a dose of 200 mW/cm2. No ocular changes other than reversible corneal epithelial injury were seen following exposure at 100 and 75 mW/cm2. There were no ocular changes after exposure at doses of 50 or 10 mW/cm2. Six-minute exposure to 76 GHz 10 mW/cm2 did not induce any detectable ocular tissue damage.
