Meibomianitis is an inflammation of the meibomian glands, a group of oil-secreting (sebaceous) glands in the eyelids. The meibomian glands are located within the structure of the lids and have tiny openings to release their secretions on the edges of the lids.

Any condition that increases the thickness of the oily secretions of the meibomian glands will allow excess oils to accumulate on the edges of the lids. This allows bacteria, which are normally present on the skin, to grow.

Excess and thickened oily secretions can be caused by allergy, adolescence, or general skin conditions such as rosacea. Meibomianitis is often associated with blepharitis, which can cause an accumulation of dandruff-like substance on the eyelids.

• Swelling of eyelid margins
• Slight blurring of vision due to excess oil in tears -- cleared by blinking
• Frequent styes

Meibomianitis can be diagnosed by eye examination. Special tests are not required.

Careful cleansing of the edges of the lids will usually minimize symptoms. Your health care provider may prescribe an antibiotic ointment to be applied to the lid edge.

Any general skin condition such as acne or rosacea may also require treatment.

Meibomianitis is not a vision-threatening condition. Most patients do well with treatment.

Call your health care provider if treatment does not lead to improvement or if styes develop.

Attention to lid hygiene will help prevent meibomianitis. Certain foods such as chocolate may aggravate the condition. Treatment of associated general skin conditions will help prevent meibomianitis.
