Blepharitis is a chronic inflammation of the eyelids. The condition affects the skin of the eyelids, and it usually involves the part of the eyelid where the eyelashes grow (lid margins) In severe cases, it may also cause styes , irritation and nflammation of the cornea (keratitis) and conjunctiva ( conjunctivitis ). Some patients have no symptoms at all. Blepharitis is usually a chronic problem that can be controlled with extra attention to lid hygiene. However, it is sometimes caused by an infection and may require medication. Commonly, blepharitis occurs when tiny oil glands located near the base of the eyelashes malfunction. When these oil glands malfunction, bacterial overgrowth can result, leading to inflamed, irritated and itchy eyelids. Blepharitis is often a chronic condition that is difficult to treat. Although it's uncomfortable and may be unattractive, blepharitis doesn't cause permanent damage to eyesight.
Blepharitis is inflammation of the edges of the eyelids, possibly with thickening scales, crusts, shallow ulcers, or inflamed oil glands at the edges of the eyelids. Symptoms include irritation, itching and occasionally a red eye. Diagnosis is by history and examination. Acute ulcerative blepharitis is usually treated with topical antibiotics or systemic antivirals. Acute nonulcerative blepharitis is occasionally treated with topical corticosteroids. Chronic disease is treated with eyelid hygiene (seborrheic blepharitis), warm compresses (meibomian gland dysfunction), and tear supplements (seborrheic blepharitis, meibomian gland dysfunction).
