What if I do nothing for my blepharitis?


If you choose not to get treatment for your blepharitis, the following complications could result:




Eye lash problems Blepharitis can cause your eyelashes to fall out or grow abnormally (misdirected eyelashes).
Scarring Blepharitis can cause scarring on your eyelids if it goes untreated for a long time.
Dry eye disease Blepharitis can cause dry eye disease. In people with blepharitis, abnormal oils and other debris from the infected eyelid can fall from the eye lid and into your tear film causing your tears to become abnormal. When the tear film is not working properly, your eyes cannot lubricate themselves properly and dry eyes or watery eyes are the result.
Contact lens problems Because blepharitis can affect the amount of lubrication in your eyes, wearing contact lenses may be uncomfortable.
Sty A sty is a red, painful lump at the edge of your eyelid, usually on the outside part of the lid and can look like a boil or a pimple
Chalazion A chalazion is a cyst in the eyelid caused by a blockage of the meibomian gland, which is one of the oil glands in the eye that is critical for making healthy tear film. When the glad becomes infected with bacteria, a red swollen eyelid develops. A chalazion is usually found on the inside of the eyelid.
Pink eye Blepharitis can cause chronic pink eye (conjunctivitis).

Corneal ulcer

Constant irritation from eyelids suffering from blepharitis can cause a corneal ulcer, which is a sore on the clear dome that covers the coloured part of your eye.
