Infrared Video Meibography of Lower Lid Meibomian Glands Shows Easily Distorted Glands: Implications for Longitudinal Assessment of Atrophy or Growth Using Lower Lid Meibography

Purpose:
To evaluate measurement reliability of the meibomian gland (MG) tissue area during infrared video meibography (IR-VM) of the lower lid.
Methods:
This is a retrospective analysis, using ImageJ, of IR-VM of 17 lids of 11 consecutive patients (age 56.6 ± 15.9 years; 9 females and 2 males) focusing on the presence of a statistically significant variation of the MG tissue area and the MG tissue area relative to the total measurement field (TMF) secondary to inadvertent lid distortion and/or an altered vertical gaze direction during a single-image acquisition video sequence.
Results:
For lids with distortions, 10 of 10 lids with distortion showed a statistically significant difference (P
