Blepharitis


Blepharitis is an inflammation of the eyelids causing red, irritated, itchy eyelids and the formation of dandruff-like scales on eyelashes. It is a common eye disorder caused by either bacterial or a skin condition such as dandruff of the scalp or acne rosacea. It affects people of all ages. Although uncomfortable, blepharitis is not contagious and generally does not cause any permanent damage to eyesight.

Blepharitis is classified into two types:
  1. Anterior blepharitis occurs at the outside front edge of the eyelid where the eyelashes are attached.
  2. Posterior blepharitis affects the inner edge of the eyelid that comes in contact with the eyeball.
Individuals with blepharitis may experience a gritty or burning sensation in their eyes, 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.

What causes blepharitis?

Anterior blepharitis 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 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.

How is blepharitis diagnosed?


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: A differentiation among the various types of blepharitis can often be made based on the appearance of the eyelid margins: Using the information obtained from testing, your optometrist can determine if you have blepharitis and advise you on treatment options.

How is blepharitis treated?

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. Some cases of blepharitis may require more complex treatment plans. Blepharitis seldom disappears completely. Even with successful treatment, relapses may occur.
