Meibomianitis occurs when the meibomian glands in the eyelid do not work properly. Excess oil released from these glands will accumulate on the eye lids. As the oil accumulates, bacteria that are normally present in the eyes and skin begin to multiply.

Any condition that increases the oil produced by these glands will cause this disorder. Below are some examples to be aware of:

  • some allergies
  • Hormones that have changed with adolescence
  • lice or eyelash mites
  • some medications that increase bacteria on the eyelids
  • contact lens solution
  • some eye makeup

In some cases, no specific cause for meibomian gland malfunction can be identified. Although meibomianitis is occasionally diagnosed in children, it is most frequently diagnosed in adults. This condition is not contagious.
