What is blepharitis?

Blepharitis is the inflammation of the edges of the eyelids. As a rule, blepharitis is a chronic disease that is difficult to treat. Anatomically distinguish:

Anterior marginal blepharitis - a lesion of only the ciliary edge of the eyelids. Posterior marginal blepharitis - accompanied by inflammation of the meibomian glands in the thickness of the eyelid, the conjunctiva and the cornea can be involved in the pathological process

In fact, in most clinical cases, both anterior and posterior marginal blepharitis is observed, that is, the eyelid is inflamed throughout its thickness.

Causes of inflammation of the eyelids

There are many causes of inflammation of the eyelids. Blepharitis can be an independent disease, for example, when the eyelids are affected by fungi, mites, bacteria, and the manifestation of any pathological process: chronic infectious and allergic diseases, hypovitaminosis (lack of vitamins), anemia, tuberculosis, diabetes, diseases of the digestive tract , Gastritis), teeth, nasopharynx, etc.

Blepharitis often occurs with farsightedness and astigmatism, and can also develop with a pronounced "dry eye" syndrome.

Common symptoms and peculiarities of individual clinical forms of blepharitis

Manifestations of blepharitis can be: redness and swelling of the eyelids, burning, itching, scales and crusts on the skin of the eyelids, stuck eyelashes, loss and incorrect growth of eyelashes, lacrimation, eyes become sensitive to bright light, quickly get tired even with a small visual load.

The following clinical forms are distinguished:

Scaly, or seborrhoeic, blepharitis is often combined with seborrheic dermatitis of the scalp, eyebrows, behind-eye areas, characterized by reddening and thickening of the edges of the eyelids with the formation between the eyelashes of scales tightly attached to the skin. When removing scales, the skin remains intact and does not bleed. At the edges of the eyelids, you can see yellowish crusts - this is the dried off sebaceous glands. Over time, the swelling of the edges of the eyelids increases, the eyelids cease to adhere to the eyeball, lacrimation appears. Sometimes the process extends to the conjunctiva and develops blepharoconjunctivitis. With a prolonged course of scaly blepharitis, partial alopecia occurs (loss of eyelashes), an eversion of the eyelid can form.

Ulcerative blepharitis is characterized by purulent inflammation of the hair lobes of the eyelashes, purulent crusts are formed, upon removal of which bleeding ulcers with a purulent coating are formed, later on their place scars are formed. Since the process involves hair follicles, eyelashes fall out. In some cases, may develop a madarose - a complete lack of eyelashes. Cicatricial changes can lead to incorrect growth of eyelashes and eyelid deformity - a turn or a twist.

Demodekozny blepharitis occurs when the eyelid mites Demodex. Initially, patients are disturbed by severe itching, especially after sleep, a sticky discharge occurs, then a pronounced inflammation of the ciliary edges of the eyelids develops, which become thickened, reddened. The secret of the sebaceous glands and cell particles form a "collar", a "muffle" at the base of the eyelashes. Dry dried out accumulates in the form of scales between eyelashes. Ticks are found at the root of the removed eyelashes during microscopic examination.

Allergic blepharitis, as a rule, is combined with an allergic inflammation of the conjunctiva. The reason is an increased sensitivity to any substance: drugs, cosmetics, dust, wool, feathers, fluff, etc. Allergic blepharitis can be both acute and chronic. The patient is disturbed by: edema of the eyelids, itching, lacrimation, mucous discharge, pain in the eyes. Usually both eyes are affected.

Diagnostics

Diagnosis of blepharitis is based on biomicroscopy - examination of eyelids and eyelashes with a slit lamp. To confirm the diagnosis of demodectic blepharitis, it is necessary to examine the newly removed eyelashes under a microscope for the purpose of detecting Demodex mites.

Treatment
