Blepharitis is a common eye disorder caused by either bacterial or a skin condition, such as dandruff of the scalp or acne rosacea. Although uncomfortable, is not contagious and can be treated.
Blepharitis is an inflammation of the eyelids causing red, irritated, itchy eyelids and the formation of dandruff-like scales on eyelashes. It affects people of all ages.
There are two major classifications of blepharitis.
Anterior blepharitis occurs at the outside front edge of the eyelid where the eyelashes are attached. It is commonly caused by bacteria (staphylococcal blepharits) or dandruff of the scalp and eyebrows (seborrheic blepharitis). It may also occur due to a combination of factors, or less commonly may be the result of allergies or an infestation of the eyelashes.
Posterior blepharitis affects the inner surface of the eyelid that comes in contact with the eyeball. It can be caused by irregular oil production by the glands of the eyelids (meibomian blepharitis) which creates a favorable environment for bacterial growth. It can also develop as a result of other skin conditions such as acne rosacea and scalp dandruff.
Individuals with blepharitis may experience a gritty or burning sensation, excessive tearing, itching, red and swollen eyelids, dry eyes, or crusting of the eyelids. For some people, blepharitis causes only minor irritation and itching. However, it can lead to more severe signs and symptoms such as blurring of vision, missing or misdirected eyelashes, and inflammation of other eye tissue, particularly the cornea.
In many cases, good eyelid hygiene and a regular cleaning routine can control blepharitis. This includes frequent scalp and face washing, using warm compresses to soak the eyelids, and doing eyelid scrubs. In cases where a bacterial infection is the cause, various antibiotics and other medications may be prescribed along with eyelid hygiene.
A differentiation among the various types of blepharitis can often be made based on the appearance of the eyelid margins:
Staphyloccal blepharitis patients frequently exhibit mild sticking together of the lids, thickened lid margins, and missing and misdirected eyelashes.
Seborrheic blepharitis appears as greasy flakes or scales around the base of eyelashes and a mild redness of the eyelids.
Ulcerative blepharitis is characterized by matted, hard crusts around the eyelashes that when removed, leave small sores that ooze and bleed. There may also be a loss of eyelashes, distortion of the front edges of the eyelids and chronic tearing. In severe cases, the cornea, the transparent front covering of the eyeball, may also become inflamed.
Meibomian blepharitis is evident by blockage of the oil glands in the eyelids, poor quality of tears, and redness of the lining of the eyelids.
Using the information obtained from testing, your optometrist can determine if you have blepharitis and advise you on treatment options. Treatment depends on the specific type of blepharitis. The key to treating most types of blepharitis is keeping the lids clean and free of crusts.
Limiting or stopping the use of eye makeup when treating blepharitis is often recommended, as its use will make lid hygiene more difficult. Warm compresses can be applied to loosen the crusts, followed by gentle scrubbing of the eyes with a mixture of water and baby shampoo or an over-the-counter lid cleansing product. In cases involving bacterial infection, an antibiotic may also be prescribed.
If the glands in the eyelids are blocked, the eyelids may need to be massaged to clean out oil accumulated in the eyelid glands.
Artificial tear solutions or lubricating ointments may be prescribed in some cases.
If you wear contact lenses, you may have to temporarily discontinue wearing them during treatment.
Some cases of blepharitis may require more complex treatment plans. Blepharitis seldom disappears completely. Even with successful treatment, relapses may occur.
Testing for Blepharitis
Blepharitis can be diagnosed through a comprehensive eye examination. Testing, with special emphasis on evaluation of the eyelids and front surface of the eyeball, may include:
Patient history to determine any symptoms the patient is experiencing and the presence of any general health problems that may be contributing to the eye problem.
External examination of the eye, including lid structure, skin texture and eyelash appearance.
Evaluation of the lid margins, base of the eyelashes and meibomian gland openings using bright light and magnification.
Evaluation of the quantity and quality of tears for any abnormalities.
Treatment at home
- Good eyelid hygiene
- Routine cleaning of the eyelids
- Frequent scalp and face washing
- Warm compresses
- Eyelid scrubs
- Limit eye makeup
- Temporarily stop contact lens wear
Directions for a Warm Soak for the Eyelids
Fill a sandwich-sized zippered baggie half-way with hot water (just from the tap, we don’t want a burn). Then wrap it with a warm wet washcloth. This miniature hot water bottle can then be held on the eyelids, giving moist heat for 10 to 15 minutes. This can be followed by gently massaging the lids to help the glands of the eyelids release their oily secretion.
