Tear film stability: A review

open access: yesExperimental Eye Research, 2013
Tear film stability can be assessed via a number of tools designed for clinical as well as research purposes. These techniques can give us insights into the tear film, and allow assessment of conditions that can lead to dry eye symptoms, and in severe cases, to significant ocular surface damage and deterioration of vision.

The thickness of the tear film

Current Eye Research, 2004
Measurements of the thickness of the pre-corneal tear film, pre-lens tear film, post-lens tear film, and the lipid layer on the surface of the tear film are summarized. Spatial and temporal variations in tear film thickness are described. Theoretical predictions of tear film thickness are discussed.

Tear Film

open access: yes, 2010
The tear film is a thin fluid film, which covers the exposed ocular surface and is essential for the health and normal function of the eye and visual system. The various components of the tear system are highly interdependent such that any abnormality in quantity or quality of the constituents can cause an imbalance in the system, leading to signs and ...

Biomicroscopy of the tear film: the tear film of the pekingese dog

Veterinary Record, 1989
Polarised light biomicroscopy was used to examine the normal pre-corneal tear film in 21 eyes of 12 pekingese dogs. The purpose of the study was to examine the influence of excessive exophthalmos on the pre-corneal tear film in the dog. The majority of the animals were found to have high levels of ocular surface contamination by particulate material ...

The neonatal tear film

Contact Lens and Anterior Eye, 2003
The importance of the tear film for the integrity of the ocular surface is well established. Full-term neonates produce tears normally, but low spontaneous blink rates during early life raises important questions regarding tear dynamics and stability. Although an afferent neural pathway that could potentially detect tear break-up is in place at birth ...
