Tear Film Break-Up Time (TBUT) Test
Tear Film Break-Up Time (TBUT) Test is a diagnostic procedure available at Desai Eye institute to assess tear film stability and diagnose dry eye syndrome. This test helps in identifying tear film abnormalities, which can lead to discomfort, irritation, and vision issues. TBUT is commonly used to detect conditions such as evaporative dry eye and meibomian gland dysfunction.
During the procedure, a small amount of fluorescein dye is applied to the eye’s surface. The patient is then asked to blink, spreading the dye evenly. Using a special blue light, the ophthalmologist observes how long it takes for dry spots to appear on the cornea. A shorter TBUT indicates tear film instability and potential dry eye disease.
The test is quick, taking only a few minutes, and is completely painless. At Desai Eye institute, our specialists use TBUT to accurately diagnose dry eye conditions and recommend the most effective treatment for optimal eye comfort and health.
