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 … Visa mer Tear film break-up time is abnormal in several conditions like aqueous tear deficiency, keratoconjunctivitis sicca, mucin deficiency, and meibomian gland disorders. Evaporative dryness can also be seen in conditions like Visa mer Ocular protection index (OPI) is used to quantify the interaction between tear film break-up time and blink intervals of a person. It is based on the idea that, even when the TBUT is normal, if the blink interval is too slow it may cause breakage of tear film due to … Visa mer • Dry eye syndrome • Schirmer's test • Fluorescein (medical use) Visa mer Procedure using fluorescein dye • Fluorescein 2% is instilled into the lower fornix of patient's eye.
