Causes of Blepharitis

​

The exact cause of blepharitis is unknown, but there are some risk factors, including:

​

• Dry eyes: Dry eyes can make it difficult to keep the eyelids clean, which can lead to blepharitis.

• Demodex mites: Demodex mites are tiny mites that live on the skin of the eyelids. They can sometimes cause blepharitis, especially in people with oily skin.

• Bacterial infection: Bacterial infection can also cause blepharitis.

• Allergic reaction: Allergies can sometimes cause blepharitis.

​

Symptoms of Blepharitis

​

The symptoms of blepharitis can vary depending on the type of blepharitis you have.

Anterior blepharitis is the most common type of blepharitis. It is caused by inflammation of the eyelids and the glands that produce oil. Symptoms of anterior blepharitis may include:

​

• Red, itchy, and irritated eyelids

• Swollen eyelids

• Crusts or scales on the eyelids

• Watery eyes

• Sensitivity to light

​

Posterior blepharitis is less common than anterior blepharitis. It is caused by inflammation of the glands that produce tears. Symptoms of posterior blepharitis may include:

​

• Red, itchy, and irritated eyelids

• Dry eyes

• Burning sensation in the eyes

• Sensitivity to light

​

Diagnosis of Blepharitis

​

Blepharitis is diagnosed by an eye doctor during a comprehensive eye exam. The eye doctor will look at your eyelids and ask you about your symptoms. They may also perform tests, such as a lid margin culture, to confirm the diagnosis.

​

Treatment of Blepharitis

​

There is no cure for blepharitis, but there are treatments that can help to relieve the symptoms. Treatment options for blepharitis include:

​

• Eyelid hygiene: The most important part of treating blepharitis is good eyelid hygiene. This includes washing your eyelids with warm water and a mild soap twice a day. You can also use a warm compress to help remove oil and debris from your eyelids.

• Medications: Your eye doctor may prescribe medications to help treat blepharitis. These medications may include:

  • Antibiotics: Antibiotics can help to treat bacterial infection.

  • Antihistamines: Antihistamines can help to treat allergic blepharitis.

  • Steroids: Steroids can help to reduce inflammation.

• Surgery: In some cases, surgery may be necessary to treat blepharitis. This is usually only done if other treatments have not been effective.

​

Prevention of Blepharitis

​

There is no sure way to prevent blepharitis, but there are some things you can do to reduce your risk, including:

​

​

• Wash your eyelids regularly: Washing your eyelids with warm water and a mild soap twice a day can help to remove oil and debris from your eyelids and prevent blepharitis.

• Avoid rubbing your eyes: Rubbing your eyes can irritate your eyelids and make blepharitis worse.

• Get regular eye exams: Getting regular eye exams can help to detect blepharitis early, when it is easier to treat.
