'Blepharitis', an inflammatory disease of the eyelids that does not heal well

The eyelids, which protect the eye from external debris and injuries, contain eyelashes within tiny hair follicles. 

 There are sebaceous glands in this hair follicle, and if the sebum discharged from it causes inflammation, 'blepharitis', an inflammation of the eyelids, occurs.

◆ What causes blepharitis?

 The cause of blepharitis is unknown, but certain factors, such as the following, are known to increase the likelihood of occurrence.

- Dandruff on the scalp and eyebrows
- Allergies
- Allergic reactions in the eyes
- Ticks on the eyelids
- Side effects of drugs
- Abnormalities in the function of the sebaceous glands
- Thick eye makeup to the inside of the eyelids

◆ What are the two types of blepharitis?

 There are two types of blepharitis: inflammation of the anterior eyelid (anterior blepharitis) and posterior blepharitis (posterior blepharitis). Anterior eyelid inflammation occurs on the outside of the eye where the eyelashes are located, and dandruff on the eyebrows and allergic reactions in the eye can cause anterior eyelid inflammation.
 Posterior blepharitis occurs in the inner corner of the eye. This form of inflammation is usually caused by dysfunction of the sebaceous glands in the eyelash follicles.

◆ blepharitis symptoms, may adversely affect vision

 Since the symptoms of blepharitis can irritate the eyes and adversely affect vision, if you have the following symptoms, you should see an ophthalmologist immediately.

- severe itching of the eyelids
- the eyelids swelling
- redness or inflammation of the eyelids
- a burning sensation in the eyes
- eyelids greasy
-eye, foreign body sensation in the eye or on
-bloodshot eyes
- tear secretion
- ticket to the eyelashes or eye corners formed
 Treatment for blepharitis depends on whether the cause of the inflammation is an infection. If there is no infection, your doctor may use steroids, eye drops, or eye ointments to relieve inflammation, and sometimes lubricant eye drops to relieve irritation from dry eyes.
 Blepharitis caused by infection is treated with antibiotics in the form of tablets, ointments, or liquid eye drops, which are used when the infection has spread outside the eyelids.

◆ What are the complications of blepharitis?

 One of the complications of blepharitis is loss of eyelashes. This can be due to scarring of the hair follicles, which can cause the eyelashes to grow incorrectly. Widespread scars can also impede the growth of eyelashes.
 In addition, there may be short-term complications such as dry eye and eye redness, and long-term complications such as eyelid scarring, sty, and chronic redness.
 If an eye infection is not treated in time, it can lead to permanent eye damage and loss of vision. Scars under the eyelids can scratch the sensitive ocular surface, which can lead to the formation of ulcers.

◆ Lifestyle habits to prevent blepharitis
 Although eyelid inflammation is not always preventable, you can take steps to significantly reduce your risk of developing eyelid inflammation.

- Wash regularly.
- Do not touch your eyes with dirty hands.
- Do not scratch when the eyelids are itchy.
