Meibomian Gland Dysfunction
The meibomian glands are rows of oil glands within the top and bottom eyelids. They produce oil that is secreted out through small openings along the edge of the lid margins.
The oil forms the uppermost layer of the tears and reduces evaporation of the underlying layers. Meibomian Gland Dysfunction occurs as a result of inflammation within these oil glands. The inflammation causes the oils produced to become poorer in either quality and quantity. This then causes or contributes to Dry Eye Syndrome.
