Blepharitis is swelling or inflammation of the eyelids. Dandruff-like debris builds up at the base of the eyelashes as well.
Eyelid inflammation; Meibomian gland dysfunction
In people with blepharitis, too much oil is produced by the glands near the eyelid. The exact reason for this problem is not known. A breakdown of these oils may lead to blepharitis.
Blepharitis is more likely to be seen in people with:
- A skin condition called seborrheic dermatitis or seborrhea. This problem involves the scalp, eyebrows, eyelids, skin behind the ears, and the creases of the nose
- Allergies that affect the eyelashes (less common)
- Excess growth of the bacteria that are normally found on the skin
- Rosacea, which is a skin condition that causes a red rash on the face
