Blepharitis: what é, symptoms, causes and treatment

Blepharitis is inflammation on the edges of the eyelids that causes the appearance of crusts, crusts and other symptoms such as redness, itching and the sensation of having a speck in the eye. This alteration is common and can appear overnight, in people of any age, and happens due to an alteration in the Meibomian glands, which are responsible for maintaining the balance of ocular moisture.

In blepharitis, these glands have difficulty getting rid of fat (a component of human tears), which accumulates in the eyelid, resulting in symptoms and increasing the risk of bacteria developing at the site, which makes inflammation more complicated..

In the presence of signs and symptoms of blepharitis, it is important that the ophthalmologist is consulted, so that it is possible to start the appropriate treatment, which usually involves the use of eye drops to clean the eyes and, in cases where there are signs of infection, the use of antibiotic eye drops may also be indicated.

See what are the main causes of itchy eyes.

Main symptoms

Blepharitis symptoms arise as a result of increased oiliness of the eyelid and proliferation of microorganisms, the main ones being:

  • Redness and swelling of the eyelids of the eyes;
  • Presence of crusting and peeling on the eyelids
  • Itchy and irritated eyes;
  • Feeling like there is a speck in the eye;
  • Constant tearing of eyes;
  • Photophobia, which is difficulty keeping your eyes open in the sun.

In addition, other symptoms that are usually present are the loss of eyelashes and during sleep the eyelids can stick together, making it difficult to open the eyes when waking up.

Causes of Blepharitis

The main cause of blepharitis is the alteration in the functioning of the Meibomian gland, which is a gland located in the eyelid whose function is to secrete fat in order to coat the surface of the eyes and prevent the tear from evaporating, giving rise to to the tear film that is responsible for lubricating and keeping the surface of the eyes he althy.

So, when this gland is altered, there is accumulation/retention of fat inside the gland, increasing the oiliness of the surface of the eyes, which makes this place for the proliferation of bacteria, which are normally present in cases of blepharitis. In addition, eyelid inflammation can also be related to skin diseases such as rosacea and dermatitis or be a consequence of allergy to eye drops, for example.

It is important that the ophthalmologist is consulted so that the possible cause of blepharitis can be identified and, thus, the most appropriate treatment can be initiated.

How the treatment is done

Treatment for blepharitis is simple and can be done by cleaning the eyes correctly using eye drops to clean the eyes and remove crusts and crusts, as recommended by the doctor. It may also be helpful to place a warm compress on the eyes daily for 2 to 3 minutes, about 3 to 4 times a day, until the symptoms completely disappear.

In the case of rosacea blepharitis, for example, the use of antibiotics in pill form may be recommended. However, the doctor may also recommend the use of antibiotic ointments, containing tetracycline or sulfa, which should be applied to the eyes before going to sleep, as they can blur vision.

How to take care of eyelids at home

In the home treatment for eyelid inflammation, you should opt for the consumption of anti-inflammatory foods such as salmon, orange and acerola to accelerate healing. In addition, chamomile compresses can help soothe skin and irritation, bringing relief from symptoms. To do this, simply prepare a chamomile tea with 1 tablespoon of chamomile flowers in 1 cup of boiling water and let it steep for 5 minutes. Then it must be strained and the solution is ready to be used.

To clean your eyes properly during blepharitis, you should:

  1. Wash your hands;
  2. Put a few drops of eye drops or chamomile tea right after its preparation on a cotton swab, gauze or compress;
  3. Look up while wiping the lower eyelid and close the eye while wiping the upper lid;
  4. Wash your hands again.

Another option is to wash the eyelid with the foam formed with neutral children's shampoo and water, as it is not irritating to the eyes.

You should not try to remove the crusts without using eye drops because removing them can make the area very sensitive and irritated.

While these symptoms are present, make-up and contact lenses should be avoided as much as possible to accelerate the healing process. The treatment time can vary from weeks to up to 1 or 2 months, and in cases of longer delay there are associated diseases, which must also be properly treated so that blepharitis can be cured.
