Blepharitis
A chronic or long-term inflammation of the eyelids and eyelashes affecting people of all ages. It is characterized by red, irritated scaly skin at the edges of the lids.
Cause. Among the most common causes are poor eyelid hygiene, excess oil produced by the glands in the eyelids, a bacterial infection, or an allergic reaction. Seborrheic blepharitis is the most common form. It is often associated with dandruff of the scalp or skin conditions such as acne.
Symptoms. Blepharitis usually appears as greasy flakes or scales around the base of the eyelashes and as a mild redness of the eyelid. Sometimes, seborrheic blepharitis may result in a roughness of the tissue that lines the inside of the eyelids or in nodules on the eyelids. Styes can also result from an acute infection of the eyelids.
A less common form of blepharitis is ulcer-ative blepharitis. It is characterized my matted, hard crusts around the eyelashes which, when removed, leave small sores that may bleed or ooze.
Treatment. Blepharitis is usually not serious. In many cases, good eyelid hygiene and a regular cleaning routine can control it. Scales can be removed with cotton moistened with warm water. The inflammation often recurs, which requires more treatment. Ulcerated eyelids must be treated by a physician, since severe cases can lead to problems with the cornea.
