Fig. 1From: Assessment of tear film lipid layer thickness in patients with Meibomian gland dysfunction at different agesThe analyzed image of lipid layer thickness (LLT) by the LipiView interferometer. The values are given in ICUs wherein 1 ICU approximately reflects 1 nm of the LLT. The average LLT of patient a was 32 nm, the average LLT of patient b was 72 nm and the average LLT of patient c was > 100 nmBack to article page
