Osmolarity of Tear Microvolumes in Keratoconjunctivitis Sicca

Archives of Ophthalmology, 1978
Determinations of tear film osmolarity were performed to evaluate their usefulness in diagnosing keratoconjunctivitis sicca (KCS) and to evaluate the possible role of elevated tear osmolarity in this disorder's pathogenesis. Tear samples were obtained using a new technique that virtually eliminates the problems of reflex tearing and sample evaporation.

Basal Tear Osmolarity as a Metric to Estimate Body Hydration and Dry Eye Severity

Progress in Retinal and Eye Research, 2018
The osmolarities of various bodily fluids, including tears, saliva and urine, have been used as indices of plasma osmolality, a measure of body hydration, while tear osmolarity is used routinely in dry eye diagnosis, the degree of tear hyperosmolarity ...

[The Tear Osmolarity of PATIENTS with Lagophthalmos].

Ceska a slovenska oftalmologie : casopis Ceske oftalmologicke spolecnosti a Slovenske oftalmologicke spolecnosti, 2017
Lagophthalmos can be characterized as the dysfunction of the eye aperture and in some cases even by the disruption of tear production. Dry eye syndrome can consequently develop. Instability of the tear film, hyperosmolarity and inflammatory reaction are considered as the key mechanisms of dry eye syndrome. In our report we monitored the tear osmolarity

Quality of vision and tear film osmolarity

Optometry and Vision Science
SIGNIFICANCE We evaluate the relationship between tear film osmolarity measurements and quality of vision in patients presenting for routine eye clinic appointments. We found that the hyperosmolar group (>316 mOsm/L) had a worse quality‐of‐vision score than the normal osmolarity group, with glare being the ...

Tear Osmolarity — A New Gold Standard?

1994
The purpose of this presentation is to propose tear osmolality measurement as a new gold standard for the diagnosis of keratoconjunctivitis sicca. Agreement on the diagnostic criteria is needed in order to permit meaningful comparisons of scientific results obtained from varying patient populations.

[Tear osmolarity and dry eye].

[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2012
Dry eye is a common eye disease, and its incidence rate has been escalating. The increased tear osmolarity is one of the main reasons for complaint, damage and inflammation of dry eye patients. With the breakthrough of testing technology for tear osmolarity, more research and application of tear osmolarity was reported, and papers on tear osmolarity of
