Blepharitis
Introduction
Blepharitis is an 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). 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.
Signs And Symptoms
Signs and symptoms of blepharitis include:
- Watery or red eyes.
- A gritty, burning sensation in the eye.
- Itchy eyelids.
- Red, swollen eyelids.
- Flaking of the skin around the eyes.
- Crusted eyelashes upon awakening.
- Sensitivity to light.
- Frothy tears.
- Eyelashes that grow abnormally (misdirected eyelashes).
- Loss of eyelashes.
The eyelids may appear greasy and crusted with scales that cling to the lashes. This debris can cause the eyelids to stick together at night. Don't be concerned if you have to pry your eyes open in the morning because of these sticky secretions. Sometimes you may notice only the presence of dried tear secretions in the morning that feel like small grains of sand.
Causes
Blepharitis is often a chronic condition that can affect the outer portion of your eyelid where the eyelashes attach (anterior blepharitis) or the inner portion of your eyelid that comes into contact with your eye (posterior blepharitis).
Conditions associated with blepharitis include:
- Seborrheic dermatitis — dandruff of the scalp and eyebrows.
- A bacterial infection.
- Malfunctioning oil glands in your eyelid.
- Rosacea — a skin condition characterized by facial redness.
Treatment
Blepharitis can be difficult to treat. Treatment includes good hygiene — regular cleaning of the area — to control signs and symptoms and prevent complications. If your condition doesn't improve, contact your doctor. He or she may prescribe an antibiotic cream or ointment. In severe cases, eyedrops containing antibiotics and steroids may be prescribed. If your blepharitis is linked to an underlying cause such as dandruff or rosacea, treating those conditions may alleviate the blepharitis.
Blepharitis rarely disappears completely. Even with successful treatment, relapses are common. Paying extra attention to good hygiene at those times may help bring the condition back under control.
