Blepharitis

Blepharitis is a common disorder that causes inflammation of the eyelids. The membrane covering the lining the white of the eye and the underside of the eyelid (conjunctiva) can become involved also. Because blepharitis tends to recur, it can be difficult to treat.

Symptoms of Blepharitis

• Redness of the eyelids
• Swelling and tenderness of the eyelids
• Itching of the eyelashes
• Flakes or scales around the eyelashes
• Crusting of the eyelashes
• Foreign body sensation or burning
• Tearing
• Sensitivity to light
• Redness of the eye
• Blurred vision
• Dry eye

Causes of Blepharitis

There are two forms of blepharitis. Anterior blepharitis affects the front part of the eyelid, where eyelashes are attached, and is caused by bacteria or scalp dandruff. Posterior blepharitis affects the inner part of the eyelid where the oil-producing glands (meibomian glands) reside, and is caused by acne rosacea or scalp dandruff (seborrheic dermatitis).

Complications of Blepharitis

Complications of blepharitis can include the development of a stye (a red tender bump on the eyelid caused by an infection of the oil glands of the eyelid), or a chalazion (a painless lump due to inflammation of the oil glands).

Treatment of Blepharitis

Treatment of blepharitis consists of eyelid hygiene and medications. Warm compresses can be applied to loosen any crusts, followed by light scrubbing of the eyelid margin with a cotton ball or swab with a mixture a baby shampoo and water or with a commercially available eyelid cleanser. When more severe, a physician may prescribe topical antibiotics or steroid eye drop or ointment medications. Acne rosacea may be treated with an oral antibiotic. Because blepharitis tends to be a chronic and recurrent condition, frequent or periodic treatments may be necessary to control the condition.
