BLINKING FREQUENCY AND THE THICKNESS OF THE LIPID LAYER.

Cornea, 2000
Dry eye is part of the computer vision syndrome. More than 80 percent of all persons using computer screens complain about visual problems.1 The dry eye is mainly caused by a reduced blinking frequency. The purpose of this work is to measure the effects of a reduced blinking frequency on the breakup time and the thickness of the lipid layer of the tear

Effect of Meibomian Gland Occlusion on Tear Film Lipid Layer Thickness

1998
The function of the meibomian glands is to provide the oil that forms a layer covering the aqueous component of the tear film, thereby preventing excess water evaporation. Should these glands become compromised, an adequate lipid layer may not form over the aqueous portion of the tear film, resulting in increased evaporation and the development of a ...

Impact of Overnight Wear of Orthokeratology Lens on Thickness of Tear Film Lipid Layer in Children with Myopia

Klinische Monatsblätter für Augenheilkunde, 2022
Abstract Background To elucidate the influence of overnight wear of orthokeratology (OOK) lenses on the thickness of the tear lipid layer (LLT). Methods We conducted a retrospective cross-sectional study of children who visited The First Affiliated Hospital of USTC between July and September 2021. LLT and blinking dynamics

Changes of the tear film lipid layer thickness after cataract surgery in patients with diabetes mellitus

Acta Ophthalmologica, 2020
AbstractPurposeTo evaluate changes in the tear film lipid layer thickness (LLT) in cataract patients with diabetes mellitus (DM) after cataract surgery.MethodsWe recruited consecutive cataract patients and recorded data regarding DM condition. Lipid layer thickness (LLT) and partial blinks rates measured with the LipiView interferometer, tear break‐up ...

Increase in Tear Film Lipid Layer Thickness Following Treatment of Meibomian Gland Dysfunction

1994
Meibomian gland lipid secretions contribute to the formation of a stable tear film. Meibomian gland dysfunction may result in dry eye symptoms, keratoconjunctivitis (Keith, 1967; McCulley and Sciallis, 1977) and contact lens intolerance (Henriquez and Korb, 1981), presumably due to an inadequate tear film lipid layer secondary to the meibomian gland ...

Evaluation of Lipid Layer Thickness Measurement of the Tear Film as a Diagnostic Tool for Meibomian Gland Dysfunction

Cornea, 2013
The LipiView interferometer (TearScience Inc, Morrisville, NC) is capable of delivering quantitative values of the tear-film lipid layer thickness (LLT). The purpose of this study was to investigate whether there is a correlation between the LLT and other diagnostic criteria for Meibomian gland dysfunction (MGD).We performed a retrospective analysis of

[Factors influencing the measurement of tear film lipid layer thickness with interferometry].

Klinische Monatsblatter fur Augenheilkunde, 2015
The quantitative measurement of the tear film lipid layer thickness is a relatively new and promising method. However, so far it has not been investigated whether there is a diurnal or a day to day variability and whether certain factors are confounding the measurement of the lipid layer thickness.In three different experimental settings, 10 subjects ...

Intelligent interferometric analysis of lipid layer thickness for clinical evaluation of dry eye disease

The Ocular Surface
Accurate and reproducible measurement of tear film lipid layer thickness (LLT) is essential for evaluating meibomian gland dysfunction (MGD) and diagnosing dry eye disease (DED). However, existing interferometric systems mainly rely on qualitative or semi-quantitative assessments, which limit their clinical utility.
