Blepharitis Information and Treatment

Blepharitis is a common condition that causes inflammation of the eyelids. The condition can be difficult to manage because it tends to recur. Blepharitis occurs in two forms: anterior blepharitis and posterior blepharitis. Anterior blepharitis affects the outside front of the eyelid where the eyelashes are attached. The two most common causes are bacteria and scalp dandruff.

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. Blepharitis does not usually affect vision or damage the eye. It is a chronic, manageable condition in most cases. If left untreated, it can lead to a more serious condition called ulcerative blepharitis . This is usually caused by a bacterial infection and can cause loss of eyelashes, eyelid scarring, and inflammation of the cornea.

Blepharitis occurs in two forms:

Anterior blepharitis affects the outside front of the eyelid, where the eyelashes are attached. The two most common causes of anterior blepharitis are bacteria (Staphylococcus) and scalp dandruff.

Posterior blepharitis affects the inner eyelid (the moist part that makes contact with the eye) and is caused by problems with the oil (meibomian) glands in this part of the eyelid. Two skin disorders can cause this form of blepharitis: acne rosacea, which leads to red and inflamed skin, and scalp dandruff (seborrheic dermatitis).

What are the symptoms of blepharitis?

Symptoms of either form of blepharitis include a foreign body or burning sensation, excessive tearing, itching, sensitivity to light (photophobia), red and swollen eyelids, redness of the eye, blurred vision, frothy tears, dry eye, or crusting of the eyelashes on awakening.
