Blepharitis is inflammation of the eyelash follicles, along the edge of the eyelid.
Blepharitis is caused by an overgrowth of the bacteria that is normally found on the skin. It is usually due to seborrheic dermatitis or a bacterial infection. Both may occur at the same time.
The cause is overgrowth of the bacteria that is normally found on the skin.
Allergies and lice that affects the eyelashes may also cause blepharitis, although these causes are less common.
People who have blepharitis have too much oil being produced by the glands near the eyelid. This allows bacteria normally found on the skin to overgrow. Blepharitis may be linked to repeated styes and chalazia. You are more likely to develop this condition if you have seborrheic dermatitis of the face or scalp, rosacea, lice, and allergies.
The eyelids appear red and irritated, with scales that stick to the base of the eyelashes. The eyelids may be: crusty, reddened, swollen, itching, and/or burning.
You may feel like you have sand or dust in your eye when you blink. Sometimes, the eyelashes may fall out.
An examination of the eyelids during an eye examination is usually enough to diagnose blepharitis.
Careful daily cleansing of the edges of the eyelids helps remove the skin oils that cause the bacteria to overgrow. Our physicians might recommend using baby shampoo or special cleansers. Antibiotic ointments may also be helpful.
Cleaning eyelids carefully will help prevent blepharitis. If a specific skin condition is present, it should be treated.
