Optical profilometry of nail dystrophies.
Optical profilometry after nail shadowing is introduced as a new technique to quantify nail surface alterations. Objective evaluations can be performed in vivo as well as on nail clippings and silicone rubber replicas. Trachyonychia, pittings, grooves and any other type of onychodystrophy are conveniently defined by 3 profilometric parameters: the mean roughness, the mean depth of roughness and the number of peaks or crests.
