Application of a pigment measuring device – Mexameter^®– for the differential diagnosis of vitiligo and nevus depigmentosus

Abstract

This study shows that the Mexameter, an objective pigment-measuring device, can be used to achieve a more accurate diagnosis of hypopigmentary disorders, and that the relative melanin index (RMI), which represents the relative pigment levels, might be a more effective parameter than the melanin index (MI) itself for comparing pigmentation differences.
