Meibomianitis
Meibomianitis is inflammation of the meibomian glands, a group of oil-releasing (sebaceous) glands in the eyelids. These glands have tiny openings to release oils onto the surface of the cornea.
Meibomianitis is often associated with blepharitis, which can cause a buildup of a dandruff-like substance at the base of the eyelashes.
The glands will be plugged and there will be less oil being made for the normal tear film. These people often presented with symptoms of dry eye.
