Blepharitis is an inflammation of the eyelids. It usually affects the edges (margins) of the eyelids. It is not a serious condition but may be uncomfortable and irritating.
Blepharitis symptoms may include one or more of the following:
You can reduce your risk of contracting blepharitis by maintaining good eye health and eyelid hygiene. Although it is a common condition, you should see an ophthalmologist as eyelid infections may result in complications such as styes, small cysts, chalazion on the eyelid or corneal infections.
What causes blepharitis?Blepharitis occurs because of a dysfunction of the oil glands (meibomian glands) that are present along the eyelid margins.
The meibomian glands are responsible for producing an oily substance that makes up part of your tears. A problem in these glands can lead to excess production of this oily substance or a blockage in the glands, which can cause the eyelids to become irritated and inflamed.
Blepharitis is often caused by bacterial infection. Everyone has bacteria on the surface of their skin, but in some people, bacteria thrive in the skin at the base of the eyelashes. Large amounts of bacteria around the eyelashes can cause dandruff-like scales and debris to form along the lashes and eyelid margins.
What puts me at risk of blepharitis?Eyelid inflammation (blepharitis) is a common condition especially among Asians. Risk factors include dandruff, dry skin, acne, diabetes or poor hygiene.
Blepharitis is often a chronic or ongoing condition, but it can be controlled with the following treatments. Your ophthalmologist will recommend an appropriate treatment for you.
Wet a clean washcloth with warm water, wring it dry, and place it over your closed eyelids for five minutes. Repeat two or three times a day. This will loosen scales and debris around your eyelashes. It also helps to unclog the oil glands.
Eyelid scrubs Use a damp facial cotton square with a drop of mild shampoo to cleanse your eyelids and gently scrub the base of your eyelashes and lid margins of each eyelid. If you are using an eyelid cleanser recommended by your ophthalmologist, follow the instructions provided. In severe cases of blepharitis, it may be necessary to scrub the eyelid two times daily. Eyelid hygiene has to be maintained on a long-term basis.
In acute stages, topical antibiotic ointment such as fucithalmic or tetracycline ointment may be prescribed. This is done by squeezing a small amount of the ointment onto the tip of the little finger and rubbing it onto the eyelid margin. Any excess ointment may then be wiped off. Some patients may need low does oral antibiotics like doxycycline to provide relief from signs and symptoms.
Steroid eye drops
If there are cornea sterile infiltrates, mild topical steroids may be used on a short-term basis. Lubricating eye drops Artificial tears are useful in treating dry eyes that is often associated with blepharitis. Other medications Omega-3 supplements in the form of fish oil or flaxseed may be useful in reducing symptoms of blepharitis.
