Thermographic evaluation of tear film break-up time to study tear film stability
International Journal of Thermal Sciences, 2016Abstract Tear film instability is one of the major characteristics of dry eye syndrome. However, traditional diagnostic method like fluorescein tear film break-up time (FTBUT) test is limited by its invasiveness, the necessity to use fluorescein sodium and thus variable result.

Importance of the Lipid Layer in Human Tear Film Stability and Evaporation
Optometry and Vision Science, 1997ABSTRACT: Purpose. Previous work on rabbits has demonstrated a four‐fold increase in tear evaporation when the tear lipid layer is removed. However, in vitro work has suggested that the lipid layer does not play a role in retarding evaporation of the aqueous layer.

Meibomian Gland Lipids, Evaporation, and Tear Film Stability
1998The tear film is a relatively complex structure of lipids, proteins, and mucins riding on the hydrophobic surface of the epithelium. It is a dynamic structure and not very stable even in normals. The ever-changing interaction between these three basic elements requires reconstitution every few seconds to maintain the health of the epithelium.

The Role of Tear Proteins in Tear Film Stability in the Dry Eye Patient and in the Rabbit
1998Sigma receptors have been identified in the lacrimal glands of rabbits; stimulation of these receptors results in the modulation of protein secretion from acinar cells. 1–4 When acinar cells were incubated with various sigma ligands, it was established that increases and decreases in protein release could be used to identify agonists and antagonists.4 ...

Contribution of the epithelium to the stability of the tear film.
Transactions of the ophthalmological societies of the United Kingdom, 1985The superficial cells of the epithelium make a mucoprotein with long chemical chains and package it in the subsurface vesicles. Subsurface vesicles fuse with the cell membrane and the side chains thus exposed join with the overlying mucus to anchor the mucus to the epithelial layer.

[The change of tear secretion and tear film stability in castrated male rabbits].
[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2002To evaluate the effect of androgen on tear secretion and tear film stability by observing the changes of ocular surface and tear film in the castrated male rabbit.Sixteen male rabbits were selected and randomly divided into the normal control group (8 rabbits) and the castrated group (8 rabbits). Schirmer's tests, tear film break-up time (BUT) and rose
