Wound Healing After Laser Injury to Skin - The Effect of Occlusion and Vitamin E

Abstract

The effects of argon and copper vapor laser irradiation of the skin of the Yorkshire pig were determined by gross and microscopic evaluation as a function of dose. For both lasers, the incident irradiance was between 3.5 and 4.5 watts/cml for a 10-14 mm beam diameter with a nearly uniform intensity profile. The dose was varied by varying exposure duration. The minimal erythemic doses for the copper vapor and argon laser exposures were 35 + 2 j/CM2 (10 second exposure) and 22.4 + 0.1 J/cm2 (6 second exposure) respectively.
