Abstract

Nail surface changes are observed during aging and in some chronic inflammatory dermatoses. Descriptive terms are commonly used, but quantitative analytic measurements are welcome to increase sensitivity, precision, and reproducibility of observations. Bioinstrumentation, particularly optical profilometry, allows both static and repetitive assessments in time in order to derive aspects of onychochronobiology.
