Adaptive parameter computation for the automatic measure of the Tear Break-Up Time

2012
Dry eye syndrome is a common disorder of the tear film, affecting a significant percentage of the population. The Break-Up Time (BUT) is a clinical test used for the diagnosis of this disease. In this work, we propose several improvements for the automatic computation of the BUT measure that solve the limitations of previous approaches.

Thermographic evaluation of tear film break-up time to study tear film stability

International Journal of Thermal Sciences, 2016
Abstract Tear film instability is one of the major characteristics of dry eye syndrome. However, traditional diagnostic method like fluorescein tear film break-up time (FTBUT) test is limited by its invasiveness, the necessity to use fluorescein sodium and thus variable result.

Confounding factors in the tear break-up time test. Influence of sequential measurements

Australasian journal of optometry, The
The tear break-up time (BUT) test is important in diagnosing and monitoring tear film stability, and understanding potential changes in tear film dynamics during repeated measurements could improve the accuracy and reliability of the test in clinical practice.The study aimed to examine the changes in BUT value caused by subsequent measurements made in ...

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.

[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.

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.

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 in contact lens wearers.

Annals of ophthalmology, 1994
The increasing number of people who wear contact lenses for longer times comfortably while achieving good vision has been attributed to advances in plastics technology. Contact lenses are now worn by any adventurous ametropic patient whose vision is capable of optical improvement.

Effect of sodium cromoglycate on tear film break-up time.

Annals of ophthalmology, 1984
Forty-one patients with an abnormal tear film break-up time entered this study. The effect, on the break-up time, of eyedrops containing 2% sodium cromoglycate was compared with placebo eyedrops. The tear film break-up time was prolonged by both treatments but the increase after sodium cromoglycate was much greater and was statistically significant ...
