The non-invasive tear film break-up time in normal children

British Journal of Ophthalmology, 2013
To perform an objective evaluation of the non-invasive tear break-up time (NITBUT) and lipid layer interferometry in normal children.Children with no known ocular surface disease or anterior segment abnormality were evaluated. We excluded patients with disorders affecting lid margins or tear film composition.

Schirmer Test and Break-Up Time of Tear Film in Normal Subjects

American Journal of Ophthalmology, 1979
We examined the precorneal film, the Schirmer test No. 1, and the break-up time tests in 440 healthy young students. There were no statistically significant differences (1) between men and women from the same origin who were brought up in the same environment, (2) between students from different ethnic origins who were brought up in the same ...

Manual interferometric device for routine non-invasive tear film break-up time assessment

Seminars in Ophthalmology, 2021
Purpose: To determine the feasibility of non-invasive tear break-up time (NIBUT) assessment using the Handheld tear lipid layer thickness assessment instrument and compare it with the standard tear break-up time (TBUT) test and other dry eye tests.Subjects and methods: 108 subjects were enrolled, 56 with and 52 without dry eye symptoms.

Tear Film Break-Up Time Before and After Watching a VR Video: Comparison Between Naked Eyes and Contact Lens Wearers

Electronics
The impact of viewing VR videos using a head-mounted display (HMD) on tear film dynamics is examined by comparing the viewing experience of individuals using their naked eyes with that of viewers wearing contact lenses.

The utility of measuring tear film break-up time for prescribing contact lenses

Contact Lens and Anterior Eye, 2018
To evaluate the clinical value of non-invasive keratograph tear film breakup time (NIKBUT) in the assessment of pre-corneal and pre-lens tear film quality for prescribing contact lenses (CLs).Forty-six subjects aged 25.5±4.3 (mean±standard deviation) years were recruited. Visual acuity (VA), anterior eye health checks and NIKBUT were evaluated.

Effect of methyl cellulose on tear film break‐up‐time in health and disease

Acta Ophthalmologica, 1987
Abstract Methyl cellulose instillation enhanced the values of BUT in healthy individuals, as well as in patients with trachoma stage III and chronic conjunctivitis, while no effect was observed in patients with squamous blepharitis.

The effect of tear substitutes on tear film break-up time.

Investigative ophthalmology, 1975
Twelve commercial artificial tear solutions and a newly developed one were evaluated as to their effect on tear film breakup time (BUT) in ten normal subjects. Instillation of one drop of these solutions altered the BUT in such a way that serial BUT measurements could be used as an index of retention time.

Non invasive tear film break‐up time and blinking

Acta Ophthalmologica, 2012
AbstractPurpose The break‐up time of the tear film for evaluation of dry eyes is performed with fluorescein in blue light of the slit lamp. Errors may occure by the observer and has to be repeated for accurat results. The BUT can also be seen with a Keratograph 4 (KG‐BUT). In this pilot‐study we want to evaluate the measurements with KG‐BUT in patients

[Tear film break-up time with different stains].

Klinische Monatsblatter fur Augenheilkunde, 1983
The tear film break-up time is usually measured with the lacrimal fluid stained with fluorescein. With the staining methods currently recommended the break-up time is difficult to reproduce. In the study described here, the break-up times with different staining methods were compared.
