Use of erythema index imaging for systematic analysis of port wine stain skin response to laser therapy

Quantitative methods to assess port wine stain (PWS) skin response to laser therapy are needed to improve therapeutic outcome. In this study, PWS skin erythema was analyzed using erythema index difference (ΔEI: erythema index difference between PWS and normal skin) images before and after treatment to investigate systematically subject‐dependent response to laser therapy.
