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 .

Norma je .When OSDI and tear break up time were analyzed, a statistically significant inverse correlation between the test scores was found; the higher or worse the OSDI score, the lower or worse the tear break up time was. The OSDI limits itself by assessing a small number of dry eye symptoms including sensitivity to light, grittiness, and pain.

Three successive (representative) values of fluorescein-instillation TBUT (tear break-up time) were obtained from a group of young Hong Kong (HK)-Chinese. The median TBUT1, TBUT2 and TBUT3 were 3.2, 3.8 and 4.5 sec, respectively. Wilcoxon signed-rank tests showed that TBUT1 was significantly differe .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 .

Aim: To compare the outcomes of non-invasive break-up time (NI-BUT) test and the other conventional dry eye tests.Methods: The right eyes of 170 subjects were included in the study.In order to evaluate the tear quality of the patients, NI-BUT levels were measured by the Scheimplug-Placido disk system (Sirius topography).If a person keeps their eyes open long enough, without blinking, their tear film will start breaking up. This makes the eye feel uncomfortable and forces you to blink to maintain comfort. In patients with dry eyes, the tear film is unstable and tends to break up faster.
