Despite steady improvement in the laser treatment of port wine stains (PWS), hypertrophic scarring remains a serious side-effect in approximately 10% of patients. The tunable dye laser (577 nm) has been shown to cause selective vascular destruction in normal and PWS skin. We have treated ten patient

Test treatment of portwine stains (PWS) was performed with a microsecondpulsed dye laser at 577nm using a 2-mm spot diameter. Although selective coagulation of the erythrocytes occurred, this did not result in bleaching of the treated area. Massive destruction of the dilated capillaries is suggested
The standard wavelength in the treatment of port-wine stains (PWS) with the pulsed dye laser is 585 nm. In many cases, the response to therapy is not adequate despite many treatments, depending partly on vessels out of reach of the laser. Longer wavelengths penetrate deeper into the dermis, but are
## SUMMARY Previous studies assessing the treatment of portβwine stains (PWS) with the 585 nm pulsed dye laser have relied on either subjective clinical assessment or __in vivo__ measurement of skin colour alone. The aim of the present retrospective study was to develop an objective method of asses
