What is it?
Meibomian Gland Dysfunction (MGD) is the leading cause of Dry Eye. Our Meibomian glands secrete the oil which coats the surface of our eyes. It also keeps the water component of our tears from evaporating or drying out. MGD is a blockage or some other abnormality of the meibomian glands so they do not secrete enough oil into the tears or the quality of the oil is of poor quality.
