Blepharitis is a disease of the margins of the eyelids. The most visible signs of this inflammation are redness of the edges of the lids and small whitish-yellow scales between the eyelashes.

Patients complain of itchy winkers, they blink more often than usual. It should be emphasized that, despite the predominant lesion of the eyelids, this disease does not always apply to a pure ocular pathology. As a rule, the main causes are inflammation of the paranasal sinuses (sinusitis, frontal sinusitis), bad teeth and diseases of the gastrointestinal tract (gastritis, gastroduodenitis, colitis). This may explain the long-term chronic course and the ineffective local treatment of blepharitis. One oculist is not able to cope here. It is necessary to do the following: ​​sanitation of upper respiratory tract, treatment at the dentist and gastroenterologist, vitamin therapy. Often, after the local foci of infection are eliminated, it goes away on its own.

However, there are such forms that can be attributed to the actual eye diseases. These occur on the background of incomplete vision correction (refractive) and caused by a demodex tick (demodectic).

In refractive blepharitis, myopic and farsighted people have to strain their eyes too much in order to see equally well near and far. Because of this, the eyes get more tired and first rapid visual fatigue, feeling of “heaviness” of the eyelids appear, and then the eye winkers turn red, scales (squamous one) and  even small sores (ulcerous one) appear on them. The only correct method of treatment is vision correction, i.e. selection of glasses or contact lenses.

Demodecosis is a microscopic mite (demodex) lives in an eyelash bulb, with up to 20 individuals occurring on one lash. By itself, this parasite is harmless, but the products of its vital activity are toxic and cause local inflammation of the edges of the lids. It is not difficult to make a diagnosis: after local drip anesthesia, 1 lash is removed from each eyelid and under the microscope the presence of a tick is excluded or confirmed. There is no reliable methods of treatment of demodicosis. But the most proven one is regular washing.

Thus, it is a chronic disease that is not very disturbing to a person without exacerbations. But it is unreasonable to neglect treatment, because over time, constant inflammation of the edges of the winkers can lead to loss (madarosis) or abnormal growth (trichiasis) of eyelashes, inflammation of the surrounding eyelids tissues (especially in children) and the eyeball itself.

Pay attention to the redness of the edges of the lids and scales at the roots of the lashes, so characteristic of some types of blepharitis.
