The tear film breakup time (TFBUT) test is a noninvasive assessment of precorneal tear film stability that is commonly performed when conjunctival hyperemia, chemosis, ocular discharge, or keratitis are noted. 4 In general, this test is performed by a veterinary ophthalmologist and requires fluorescein stain, a cobalt filter, and slit-lamp .The mean tear film break up time (TBUT) in test groups were 4.88 seconds± 0.34(lithium group), 4.81 seconds ± 1.60 (valproate group) and 15seconds± 2.0(control group), respectively. No statistically significant differences were observed between the first and the second groups in TBUT values, but significant differences were found between the .

Tear breakup time (TBUT) is the most frequently used measurement to assess for tear film stability. It is determined by measuring the interval between instillation of topical fluorescein 0.5% and appearance of the first dry spots on the cornea. . (TSAS) is a noninvasive and objective test that is used to help diagnose tear-film instability . 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 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.
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. TBUT test is subjective, labour-intensive and time-consuming. These weaknesses make a computer-aided diagnosis of DED highly desirable.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. .

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 .Tear break up time (TBUT) TBUT is an indication of tear film stability. . did not find a significant correlation between TFO and MMP-9 levels or with any other clinical dry eye test. Tear film interferometry.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 . An unstable tear film can explain dry eye symptoms in patients who have a normal quantity of tears. Unstable means that the composition of the tears is imbalanced, resulting in tears evaporating too quickly or not adhering properly to the surface of the eye.
Introduction. The tear film is a thin structure (about 2.0–5.5 µm thick 1, 2), extremely sophisticated in functioning and composition with a crucial role in maintaining ocular surface physiology.The assessment of tear film is of paramount importance in diagnosing dry eye disease (DED) 3, One aspect of the tear film which is crucial to investigate for DED diagnosis .Objective: To compare tear film breakup time test with Schirmer's test in patients with pterygium. Methods: The case-control study, involving 86 patients with unilateral primary pterygium aged between 30 and 70 years, was conducted at the Department of Ophthalmology, Karachi Medical and Dental College, Abbasi Shaheed Hospital, from May 2009 to December .
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 .Investigation of fluorescein stain–based tear film breakup time test . 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 lens and the tear film are the variable factors of the refractive system. During the last few years, several studies had reported that the tear break-up reduced the optical quality. [10–15] The tear break-up is a dynamic process and any local changes of the tear film after blink will cause changes of the optical quality. The purpose of . The diagnostic test of the first choice for the tear film stability assessment, proposed by TFOS DEWS II, is non-invasive tear break-up time (NIBUT) since the instillation of fluorescein during fluorescein tear film break-up time (FBUT) measurement alters the ocular environment [2].

Introduction. Dry eye disease (DED), a disorder of the tear film due to tear deficiency or excessive tear evaporation, damages the interpalpebral ocular surface and is associated with symptoms of ocular discomfort 1.DED is diagnosed by triaging questions; risk factor analysis; diagnostic tests, such as questionnaire, non-invasive tear film breakup time .
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.

T Inomata et al., “Maximum blink interval is associated with tear film breakup time: A new simple, screening test for dry eye disease,” Sci Rep, 8, 13443 (2018). PMID: 30194447. 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 .
