Blepharitis

Blepharitis 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, blepharitis doesn't cause permanent damage to eyesight.

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. Sometimes you may notice only the presence of dried tear secretions in the morning that feel like small grains of sand.

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

Blepharitis may be caused by a combination of factors. Less commonly, blepharitis may result from allergies or even an infestation of lice on the eyelashes.

If your signs and symptoms don't seem to be improving despite good hygiene — regular cleaning and care of the area — make an appointment to see your doctor.
