Abstract
Argon laser therapy of superficial pigmented lesions in both young and old people is associated with a risk of complications including delayed wound closure and hypo/hypertrophic scarring. Problems may also occur after treatment of lesions located on the eyelid. To minimize the risk of these problems coagulation of deep tissue should be avoided. We discuss a technique using mercurochrome, a red-colored compound that absorbs the blue and green lines of the argon laser, as a barrier for the irradiated light that eliminates these complications and we provide probable reasons for this technique's effectiveness.
