Blepharitis Risks & Symptoms


Despite being uncomfortable, blepharitis is usually not a serious condition.  Risk and complications are few and rare, however, having said that, there are some which you may wish to look out for.

Meibomian Cyst

This occurs when an irritated tear gland swells in the eyelid. Applying a hot compress can reduce swelling though it may just disappear on its own. If a cyst becomes infected, antibiotics may be prescribed. If still persistent then a routine operation under local anaesthetic can remove it.  Also known as the Chalazion, it is painless and the swelling usually occurs on the inside of the eyelid.  The swelling can become infected and painful and occurs when the small oil glands in the eyelid become blocked.  <

Sty

This is, unlike the cyst, a painful swelling and occurs on the outside of the eye. It affects the rim of the eyelid and is caused by infection of the eyelash follicle. Treatment usually involves frequent hot compresses to the eye.  This should be sufficient for most occurrences though more serious cases may require antibiotics.  Symptoms you should look for include swollen or painful eyelids that may appear red and tender.  There may also be visible abscesses forming on the eyelid.

Dry Eye Syndrome

This occurs when insufficient activity of the tear gland makes the eye dry. All the usual symptoms of blepharitis can be present as well as blurred vision.  Dry eye syndrome, is caused by glands producing insufficient oils to properly lubricate and moisturise the eye.  Symptoms are normally treated by applying tear substitute drops which, are available without prescription.  There may be a sandy or gritty feeling within the eye, accompanied by a burning sensation.  Eye pain and slightly blurred vision are not uncommon too.  Alternatively, you may experience excessive tearing and watering eyes. 

Eyelashes

With the more severe and long standing cases of blepharitis, the eyelashes may be affected.  This may include such conditions as madarosis, whereby the eyelashes can fall out.  Trichiasis, is where the eyelash is misdirected and can interfere with the eyeball, and finally, poliosis, involves de-pigmentation of the eyelashes.

Conjunctival Phlyctenules

This is a condition whereby tiny hard lumps, around 1-3 millimetres in length appear in the lower part of the eye, under the cornea.  They are yellowish triangular lumps, and surround the small blood vessels.  This can usually be treated with antibiotics, or prevented with regular eyewashes and good hygiene.   Conjunctivitis, or chronic pink eye as it is also known, can be contracted.
