Summary

Two methods allow to evaluate tear breakup time (BUT): without prior dye instillation (No Dye BreakUp Time NDBUT) or after fluorescein instilation (FBUT). The interconnections between those two values are unknown

Conditions

Interventions

DIAGNOSTIC_TEST

No Dye BreakUp Time

Measurement without dye of the tear meniscus height (TMH) which give an rapid hint on the quantity of tears present on the ocular surface, the measure in real time of the tear osmolarity and, at last, the analysis of the thickness of the tear's layer by interferometry (measurement of the light fringes reflected by the tears when illuminated with polarized light, whereby the complete layer or the lipid layer alone can be evaluated separately depending on the machines used) and of the assessment of the quality of the Meibomian glands (non-contact imaging by infrared illumination).
