Development in Tear Film Osmolarity Assessments: A Review

نویسندگان

چکیده

The aim of this article is to review the development in assessment tear film with osmolarity techniques. Also, find out average score for normal and keratoconjunctivitis sicca (KCS) patients based on published work.
 use techniques has been started about 50 years ago. Over last a number researchers have investigated human osmolarity. two procedures. first procedure which old, that involves detection freezing point depression vapour pressure. second one more advance known as electronic method, electrical impedance technique.
 All used assess are good, accurate, reliable provide comparable data. Based work reviewed article, subjects 303.2 ± 7.0 compared 322.7 15.9 KCS.

Tear film stability: a review.

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. Understanding what drives tear film instability and its assessment is al...

Tear film osmolarity: determination of a referent for dry eye diagnosis.

PURPOSE To determine new referents, or cutoff levels for tear film hyperosmolarity in the diagnosis of keratoconjunctivitis sicca (KCS) and to assess their effectiveness in independent patient groups. METHOD A meta-analysis was performed on published data for tear osmolarity in samples of normal eyes and various subtypes of dry eye, and pooled estimates of the mean and standard deviations for...

Tear film osmolarity and ocular surface disease in two rabbit models for keratoconjunctivitis sicca.

We report the natural history of keratoconjunctivitis sicca (KCS) in two rabbit models. The first one (full KCS model) was created by closing the lacrimal gland excretory duct, and removing the nictitating membrane and harderian gland. We created the second one (lacrimal gland duct only [LGDO]-KCS model) by closing the lacrimal gland excretory duct. Although tear film osmolarity was abnormally ...

Oral sea buckthorn oil attenuates tear film osmolarity and symptoms in individuals with dry eye.

Dry eye is a common condition that can severely impair the quality of life. We aimed to find out whether oral sea buckthorn (SB) oil, containing (n-3) and (n-6) fatty acids and antioxidants, affects dry eye. In this double-blind, randomized, parallel trial, 20- to 75-y-old women and men experiencing dry eye symptoms consumed 2 g of SB or placebo oil daily for 3 mo from fall to winter. One hundr...
