•Tear turnover is the summation of tear secretion, exudation, evaporation, drainage and corneal or conjunctival permeability.•The most common way to assess tear turnover is to follow the elution of dye by monitoring decreased fluorescence over time.•We show that fluorescein profilometry can be utili...
