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
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.
