The dynamics of the tear film are reviewed with specific reference to the biophysical aspects:
distribution, turnover and elimination through evaporation, drainage, and absorption. The …

The conditions of tear film formation and stability are governed by the surface chemical
characteristics of the tear film system and by the proper functioning of the lacrimal apparatus …

Meta-analyses were carried out of studies of tear production (by fluorophotometry, tear
turnover rate [TTR]) and evaporation (from capture of fluid loss from the eye). TTR was …

Great strides have recently been made in quantitative measurements of tear film thickness
and thinning, mathematical modeling thereof and linking these to sensory perception. This …

Although other authors in this Symposium volume will also cover the structure of the tear
film, and the nature and origins of its components, it is worth mentioning the current picture …

Tear hyperosmolarity is thought to play a key role in the mechanism of dry eye, a common
symptomatic condition accompanied by visual disturbance, tear film instability, inflammation …

A healthy tear film is very important for many major functions of the ocular surface. Dry eye
disease is a significant clinical problem that needs to be solved but the poor correlation …

Tear clearance/turnover provides a global assessment of the function of the lacrimal
functional unit and of tear exchange on the ocular surface. It is an indirect measure of dry …

The tear film is a nourishing, lubricating and protecting layer that bathes the ocular surface. It
is continuously replenished through cycles of production and elimination via evaporation …

The dynamics of tear flow were studied for human subjects using fluorescein as an indicator.
A new fluorophotometer attachable to a slit lamp was designed to determine fluorescein …
