From: Relationship between meibomian gland loss in infrared meibography and meibum quality in dry eye patients

Meibum secretion from the orifices of two adjacent meibomian glands in the area of focal dropout (two arrows). To precisely analyze the direct correlation between meibomian gland dropout in meibography and meibum quality, we evaluated 31 eyes of 23 patients with focal dropout (loss of 1 or 2 adjacent meibomian glands) in meibography. While squeezing the eyelid in the region of the focal dropout, we recorded the meibomian glands and the secretion with an infrared charge-coupled device infrared video camera (acA1600-20um; Basler Inc., Ahrensburg, Germany). The color of the meibum was visually evaluated through a slit-lamp microscope. Using this procedure, we checked the meibum secretion from the orifices of 1 or 2 adjacent meibomian glands in the region of the focal dropout
