Blepharitis is a common disease of the eyelid, one which affects anywhere from 15-25% of the population. However, Blepharitis is not often discussed, and its symptoms are often mistaken for other illnesses, such as pink eye. So, let’s talk briefly about this disease and everything you should know about it.
What is Blepharitis?
Blepharitis is an inflammation of the eyelid – usually the upper eyelid, but potentially both eyelids. This causes uncomfortable redness and itching, along with a buildup of crust on the eyelashes that can sometimes make its way into the eyes themselves.
There are two different types of Blepharitis, with their own causes.
Posterior blepharitis is an inflammation in the inner edge of the eyelid, where it touches the eye. This is typically caused by the oil glands in the eyelid becoming clogged, either from poor cleaning or from bacterial buildup. Skin conditions like dandruff and rosacea can also cause posterior blepharitis.
Anterior blepharitis, on the other hand, is an inflammation of the outer eyelid, around the eyelash follicles. This can be caused by bacterial buildup, or from dandruff flakes getting caught on the eyelids. In some cases, allergies or even skin mites can cause anterior blepharitis as well.
Regardless of the cause, blepharitis is not communicable. It looks unpleasant, but it isn’t a danger to others.
Treatment of Blepharitis
The good news is that blepharitis is not particularly harmful. If gone untreated, it might cause styes or chalazions (hard lumps) to form on the eyelid, which are also unpleasant but not dangerous. In worse cases, a severe buildup of crust might potentially damage the cornea by scratching it, although this is rare.
In many cases, blepharitis will clear up on its own, after a few days. If not, there are a few options for treatment.
Most of the time, all that’s needed is using gentle “no tears” soap and warm water to wash the area thoroughly and keep it clear of crust.
If the blepharitis is caused by bacteria, your eye doctor might prescribe antibiotic eyedrops to help speed up recovery. If the inflammation is severe, they might also recommend steroidal anti-inflammation eyedrops to treat the symptoms.
Or, if the blepharitis is caused by other skin conditions, like dandruff, treating that will usually also cure the blepharitis.
If your eyelids are swollen and painful, or your eyes are frequently covered in far more crust than usual, you may have blepharitis. Contact Valley Eyecare Center in Phoenix for a checkup and treatment recommendations.
