Tear film break up time test
WebbQualitative tear film abnormalities can be diagnosed by measuring the tear film breakup time (BARABINO et al., 2004). Animals with qualitative disorders can show normal STT values (GRAHN & STOREY, 2004). The tear film breakup time is evaluated by biomicroscopy using a cobalt blue filter after topical instillation of fluorescein. 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. The volume of tear in the eye depends on two factors, drainage through the lacrimal passages and evaporation. Factors like decreased tear production, increased evaporati…
