The dry eye problem and its treatment
The eyes are the mirror of our soul. And if something is wrong with them, it immediately becomes noticeable not only to us, but also in some cases to others. But some changes and problems in the functioning of the organs of vision are especially unpleasant. One of these problems is the so-called dry eye. Is it possible to deal with this? And how to do it right?
The essence of the problem
To begin to understand the essence of the functioning of the organs of vision. The surface of the eye covers a special shell: the cornea and conjunctiva (it also lays the inner surface of the eyelids). Normally, these parts should be constantly wet. Moisture plays a very important role, performing the function of protecting the eyeball from external negative influences. But where to get this moisture?
The lacrimal glands produce fluid. And this liquid is what stands out during crying. This is the most ordinary tear. It forms the finest tear film that covers the surface of the eye, which becomes uniform when blinking.
Such a film performs several functions: it plays the role of a lubricant, cleans the cornea, ensures correct visual perception, removes foreign bodies, smoothes out surface irregularities, and so on. Fluid is released through the tear ducts.
If such processes as the formation or abstraction of a lacrimal fluid are disturbed, and its composition changes, the film simply will not form. This phenomenon is referred to as "dry eye syndrome". It is important to find out in time how to treat such a condition, because in the absence of the necessary measures, the functioning of the organs of vision will be impaired. In this case, Israeli doctors will help you - Ophthalmology in Israel is very developed and will help you get rid of the undesirable consequences of this syndrome.
Is it dangerous?
We will touch the consequences of increased dryness of the eyes. Here are some possible:
- Due to the lack of a protective film, the surface will become susceptible to the activity of bacteria and other pathogenic organisms, so that the risk of infections will increase.
- The cornea due to increased dryness will be damaged, which, in turn, can lead to the formation of erosions.
- Because of the consequences listed above, a person can lose his vision (both partially and completely).
So, it’s not worthwhile to be irresponsible and not serious about this problem, measures should be timely.
What could cause such a problem?
Dry eyes can not appear by itself, such a condition may be due to the influence of some negative factors. We list the possible causes of dry eye syndrome:
- The impact of negative environmental factors such as smog, urban dust, exhaust, cigarette smoke, evaporation of chemicals and so on.
- Often such a problem affects those who constantly use heating and air conditioning (they remove moisture from the room, making the air excessively dry).
- Wearing contact lenses or non-compliance with the rules of their wearing.
- Unfavorable working conditions at the computer or with documents (for example, incorrect or insufficient lighting).
- The use of low-quality cosmetics for the eyes.
- Overwork of organs of sight, increased loads: prolonged stay at the computer, watching TV for more than 3-4 hours a day.
- The lack of certain vitamins (in particular, vitamin A) or other substances (lipids that affect the composition of the tear fluid).
- Age changes.
- Hormonal disorders.Often the development of increased dryness is associated with menopause or menopause in women, but other problems in the work of the endocrine system (for example, thyroid pathology) may also be the cause.
- The impact on the cornea of natural factors: wind, cold, direct sunlight.
- Uncontrolled or prolonged use of certain drugs. These include anti-hypertension drugs, antihistamines, antidepressants, vasodilators, and so on.
- A spasm of blood vessels and, as a result, an insufficient supply of oxygen and nutrients to the cornea.
- Damage to tear ducts.
- Violation of the integrity of the cornea.
- Endured operations on the organs of vision.
- Multiple sclerosis.
- Inflammatory diseases of the organs of vision (for example, meibomite, that is, inflammation of the meibomian glands located in the eyelid).
- Scleroderma and other skin diseases.
Now let's list the symptoms of this condition:
- There is a burning sensation and rezi in the eyes. Such sensations are often aggravated by exposure to dust, wind, dry air, and other negative factors.
- Itching is also observed.
- Sometimes there is a feeling of a foreign body in the eye.It seems that something is interfering, something is on the cornea. But when you look around you can not find anything.
- In the early stages of the development of the state, an increase in tearing may be observed as a compensatory phenomenon. But gradually it decreases and comes to naught.
- The cornea can blush, become covered with small vessels.
- The clarity of vision may be disturbed, a feeling of blurred arises, and the clarity decreases. But, as a rule, all this passes after repeated blinking or closing of the eyelids for a certain period of time.
- Also, there is often discomfort in the eyes, which increases after visual loads.
To identify the problem, the ophthalmologist may prescribe a number of diagnostic procedures. For example, to determine the amount of tear fluid, eyelids are attached to strips of special paper treated with special developing substances.
After 5 minutes, the results are evaluated. Drops with coloring components may also be instilled into the eyes. Such measures will assess the integrity of the tear film and identify violations.
How to treat?
Treatment of dry eye syndrome implies the elimination of the cause of the development of this condition, relief of concomitant symptoms,as well as the normalization of the production and outflow of tear fluid and the improvement of its composition. Here are some possible measures:
- In case of hypovitaminosis or avitaminosis, a complex of certain vitamins will be prescribed, the deficiency of which takes place.
- Apply local products that allow to moisturize the cornea and get rid of dryness. The composition of such funds usually includes components such as lipids, hyaluronic acid, polymers and others. Such drops as “Artificial Tear”, “Sustain”, “Vizin” and others can be used. It is best to choose drugs that do not contain preservatives (they can irritate the cornea, and this is undesirable). But from the use of funds that remove redness due to vasoconstriction, should be abandoned. The use of such drops can aggravate the problem.
- You may have to change your lifestyle or profession if conditions are extremely unfavorable. Excessive visual stress will need to be avoided.
- Can be used and folk remedies, such as decoctions of chamomile and some other herbs (for instillation) or carrot juice (for use inside).
- In severe cases, surgery is indicated, during which a stopper will be placed in the opening of the tear duct to close it. Such measures will reduce the loss of tear fluid (because the natural outflow will be reduced).
