Unauffällig zu werten ist eine Break-Up-Time von 20 bis 30 Sekunden. Bei einer Break-Up-Time von weniger als 15 Sekunden kann von einem instabilen Tränenfilm ausgegangen werden. Unter einer Break-Up-Time 10 Sekunden besteht Verdacht auf einen verminderten Muzingehalt der zu Komplikationen führen kann.
Fluorescein Tear Break-up Time Test. The first version of the TBUT test is the fluorescein tear break-up time (FBUT) test, which is commonly referred to as the traditional method of tear film testing in the literature and has been used in ophthalmology practice for almost half a century [2], [9] – [10]. It can be performed anywhere where .
The diagnosis should be performed carefully on the basis of the patient's symptoms and the TBUT test, because the ocular surface appears normal and remains unstained. . Clinical efficacy of topical 3% diquafosol tetrasodium in short tear film break-up time dry eye [in Korean].

(benzalkonium chloride can increase tear break up speed). . did not find a significant correlation between TFO and MMP-9 levels or with any other clinical dry eye test. Tear film interferometry. If a patient blinks before the tear film breaks up, even with training, then the time is recorded as TBUT. The lower median TBUT between two eyes should be used in making clinical diagnosis. Besides subjective observation techniques, several devices can measure the TBUT objectively, including the Oculus Keratograph 5M.
The aim was to determine feasibility and reliability of noninvasive tear break-up time (NIBUT) assessment using handheld lipid layer examination instrument, and to compare it with standard tear break-up time (TBUT) test. Fifty patients were enrolled, 31 with and 19 without dry eye symptoms. Schein q . Tear Break Up Time: How it is checked and what does your eye surgeon see under the microscope? . A short tear break-up time is a sign of a poor tear film. Generally: >10 seconds is thought to be normal. 5 to 10 seconds, marginal dry eye . This information along with a Tear Osmolarity test, your eye surgeon will be able to determine the .

Changes caused by fluorescein in the tear film evaluated with hybrid break-up time test as a new method—Part Two: Its effect on breakup locations and other .
Tear film stability is the key event in ocular surface diseases. The purpose of this study is to evaluate spatial and temporal progression of the tear film breakup using an automatic non-invasive device. Non-invasive tear breakup time (NITBUT) parameters, such as First NITBUT (F-NITBUT) and Average NITBUT (A-NITBUT), were evaluated in 132 glaucoma and .
This study aims to investigate the reliability and efficacy of maximum fluorescein tear break-up time (FTBUTmax) in diagnosing dry eye disease (DED). 147 participants were enrolled in this study. The accuracy of tear film breakup time estimation was 0.789 (95% confidence interval (CI) 0.769–0.809), and the area under the receiver operating characteristic curve of this AI model was 0.877 .
In 2016, the Asia Dry Eye Society (ADES) implemented new diagnostic criteria for dry eye that enabled diagnosis with only subjective symptoms and decreased tear break-up time (TBUT) (≤5 seconds). The tear film instability plays an important role in the pathophysiology of dry eye, as the unstable tear film is the pivotal mechanism of dry eye. This new definition stresses stability of the tear film as well as the importance of visual impairment, highlighting the essential role of tear film break up time (TBUT). A TBUT of less than or equal to 5s, considered to be decreased, is now categorized as a criterion for DED by this new definition [3] .
Methods. 108 patients were enrolled in this cross-sectional study and divided into two groups: patients with dry eye (n = 57) categorized by the presence of dry eye symptoms obtained by Schein Questionnaire and minimally-one objective dry eye sign (tear film break-up time <10 s or corneal, conjunctival and lid margin fluorescein staining), and healthy subjects (n . The fluorescein tear film breakup time (FBUT) measurement is a clinical test that is routinely used to assess the stability of the tear film despite its invasiveness.

Tear Break-Up Time (TBUT) is a crucial diagnostic test used in optometry to assess the stability of the tear film, an important factor in eye health and comfort. This test measures the interval between a complete blink and the appearance of the first dry spot on the corneal surface after the instillation of a fluorescein dye. Tear break-up time (TBUT) remains one of the most commonly employed tests to assess tear film stability and for dry eye diagnosis [1,2]. First introduced by Norn in 1969, TBUT was defined as the time “interval between the last complete blink and the presentation of the first appearance of a dry spot or disruption in the tear film” [2,3]. While many variations exist, the . The tear film breakup time (TBUT) test is a common clinical test used to diagnose DED. In this test, DED is diagnosed by measuring the time at which the first breakup pattern appears on the tear film. .
