Ocular temperatures during infrared or millimeter wave exposure were measured with thermography, fluoroptic thermometer, and microencapsulated thermochromic liquid crystals (MTLC) method. MTLC showed good correlation with ocular damage.
In vivo ocular temperatures in rabbits were measured during 40 GHz millimeter-wave exposure (400–100 mW/cm2). To visualize aqueous humor convection, 0.2% microencapsulated thermochromic liquid crystals (MTLCs) were injected into the anterior chambers of rabbit eyes. Exposure to 40 GHz increased corneal, lens and retrobulbar temperature, with aqueous humor convection having an important role in heat...
Acute ocular damage threshold of 40 GHz millimeter wave (MMW) exposure was investigated. Pigmented rabbits were exposed unilaterally to 400, 300, 200 or 100 mW/cm2 40 GHz MMW for 6 minutes by a lens antenna under systemic anesthesia. Ocular changes were evaluated by slit-lamp biomicroscopy. Miosis and corneal epithelial damage except corneal stromal opacification were observed immediately after 6...
