Eyelid inflammation, known as blepharitis, is a common condition in which the eyelid gets inflamed and coated with oily particles and bacteria. Blepharitis is commonly associated with eyelid swelling, redness, itchiness, and stinging or burning in the eyes.
There are four main types of blepharitis: anterior, posterior, mixed, and rosacea blepharitis.
Anterior blepharitis is characterized by inflammation on the outside of the eyelid where the eyelashes are attached. The cause is usually bacterial or, in some cases, viral.
Posterior blepharitis is a dysfunction of the eye’s oil glands located in the eyelids at the base of the eyelashes. Clogging of the glands can result in thickened eyelid margins and crusty eyelids.
Mixed blepharitis is when anterior and posterior types occur at the same time.
Blepharitis as a condition is not fully understood, but generally the cause depends on the type of blepharitis. Therefore, common causes of blepharitis are bacterial or viral infections, dry eye syndrome, malfunctioning oil glands in the eyelid, and ocular rosacea.
Symptoms of blepharitis include:
Complications resulting from blepharitis include eyelash problems, eyelash loss, eyelid skin problems, excessive tearing or dry eyes, difficulty wearing contact lenses, formation of a stye or chalazion, chronic pink eye, and injury to the cornea.
To diagnose blepharitis, your doctor will examine your eyelids and swab the skin to be tested. The doctor will also swab the oil or crust to be analyzed for the presence of bacteria and fungi, or for evidence of an allergy.
Treatment includes medication for any present infections, antibiotics directly applied to the eyelid or as eye drops, medications to control inflammation, medications to control the immune system, and treatments to address any other underlying issue.
It’s important to note that even with prescribed treatment blepharitis rarely completely goes away, as it’s often a chronic condition. It is up to you to take the necessary steps to keep it under control to prevent a flare-up.
Maintaining proper eyelid hygiene is a good way to prevent blepharitis flare-ups. As a chronic condition, it requires lifelong care to avoid complications. Here are some pointers for proper eyelid hygiene you should practice to prevent blepharitis.
By following these steps and your doctor’s instructions, you can have greater success in preventing blepharitis.
