Direct thermocouple measurements of temperature rise and heat conduction in the rabbit retina.

For a given burn, a greater dose was required to raise the temperature to the same level tuhen the spectral distribution of the source included both the visible and the near infrared. Temperature rises compatible with steam production have not been obtained even for very intense burns. In cases of retinal explosion the temperature rose above 40° C, which when added to the body temperature gave a total of about 78° C, sufficient to produce albumin coagulation. Temperature rises 1 or 2 nun. awaij from the center of the burn remained below 2° C. regardless of the intensity of the burn.
