Tear break-up time (TBUT) also known as tear film break-up time (TFBUT) is the time taken for the first dry spot to appear on the cornea after a complete blink. TFBUT measurement is an easy and fast method used to assess the stability of tear film. It is a standard diagnostic procedure in the dry eye clinics. [1]
A tear breakup time (TBUT) test measures the time it takes for tears to break up in the eye. [4] The tear breakup time can be determined after placing a drop of fluorescein in the cul-de-sac. [14] [30] A tear protein analysis test measures the lysozyme contained within tears. In tears, lysozyme accounts for approximately 20 to 40 percent of ...
Newer and better tests of tear production and function are now emerging. [citation needed] One test measures an iron-binding molecule called lactoferrin. The amount of this molecule appears to be closely related to tear production. Patients with low tear production and dry eyes have low levels of this molecule.
Artificial tears work by adding similar lubricating elements that natural tears contain. [17] This helps thicken and stabilize the pre-corneal tear film, prolonging tear film breakup time, and allowing for tears to properly protect the surface of the eyes. [17] Most artificial tears do not require a prescription and can be used as often as needed.
