FCT = fluorescein clearance test measuring the average wetting length (mm) for 1 min with Schirmer strip (with anaesthetic) at 10 and 20 min time points. Reflex = reflex tearing determined by nasal stimulation performed at the 30 min time point (present: wetting length (mm) greater than the above baseline value; absent: wetting length equal to or no greater than the baseline value). DTC = delayed tear clearance measured by FCT (absent: no DTC and is found in normal subjects when dye cleared within 20 min; present: dye clearance was delayed more than 20 min). BUT = tear break up time (seconds). MGD = meibomian gland dysfunction determined by meibum expression (absent: meibum was readily expressed; present: meibum poorly or not expressed by digital compression). PM = as the day progresses; AM = upon awakening; F = female; m = male; FL = fluorescein; RB = rose bengal.
