White spots in the eyes when you look. Gradual or abrupt narrowing of the field of vision. Change in corneal structures

Such defects occur both in the lens of the eye itself and in its outer shell - the sclera and cornea. Clouding of the lens is called a cataract, and white spots on the cornea of the eye are called a thorn (leukoma). Such diseases are a path leading to complete loss of vision, so it is important to know their causes and treatment. Today we will talk about them as well as ways to prevent these diseases.

Causes of white spots on the eyes

Leukoma- this is a partial or complete clouding of the cornea of \u200b\u200bthe eye. The causes of leukoma can be the following:

Tuberculous or syphilitic keratitis, the outcome of which is extensive corneal scarring with the formation of massive leukomas.

Other infectious diseases eyes, corneal ulcers (eg, trachoma).

Chemical burn of the eye, especially with alkali solutions. In this case, vision can suffer very much, up to the ability to only distinguish light from darkness.

Eye injury (including scarring after an unsuccessful surgical intervention).

White spots on the cornea look like white formations visible to the naked eye, and in the form of microscopic areas of turbidity (clouds, specks). The small size of the leukoma affects vision less, and the smallest microscopic spots may generally go unnoticed by their owner.

congenital leukoma as a cause white spot on the eye

Depending on the cause that led to the appearance of corneal opacity, leukomas are congenital and acquired. The following types are usually distinguished:

Acquired leukoma.

congenital leukoma. It is the most rare form pathology of the eye and occurs as a result of the transferred inflammatory process, sometimes due to the presence of a defect in fetal development.

Acquired leukoma as the cause of a white spot on the eye

Among eye diseases leading to blindness, special place occupies leukoma (leukoma). In fact, this is clouding of the cornea, which causes a number of factors. Sometimes a white spot on the eye leads to a complete loss of vision, so every person needs to know the causes and treatment of leukoma.

Corneal clouding can form after trauma or inflammatory diseases(keratitis, corneal ulcers, trachoma). As a result, the original transparency is lost, and outer shell the eye in the iris becomes white. In the future, the walleye acquires a yellow tint due to hyaline or fatty degeneration.

Often, a leukoma looks like a scar visible to the naked eye or like small whitish white spots that can only be detected with magnifying instruments.

After suffering keratitis (tuberculous or syphilitic lesion eyes). In this case, the scar is massive, the thorn is extensive.

Impact chemical substances on the mucous membrane of the eye. In terms of education following chemical burn scars are the most dangerous various solutions alkalis. After exposure to such liquids, a person can completely lose normal vision (only the ability to perceive light remains).

traumatic injury eyes.

The appearance of a thorn after an unsuccessful surgical treatment on the mucous membranes of the eye.

Causes of white spots on the eyes with cataracts

Cataract- this is a partial or complete clouding of the lens, which is noticeable as a white or gray spot on the pupil. Like leukoma, it can be congenital or acquired, the latter being much more common. Congenital cataract among all congenital defects of the organ of vision is almost half of the cases.

It is believed that the main cause of the development of clouding of the lens is degenerative change the transparent substance of the lens itself. In this regard, cataracts are most common in the elderly.

Treatment of white spots on the eyes

Currently, the treatment of leukoma is usually surgical, using laser technology. The best treatment is white spots that have arisen after suffering ophthalmic diseases infectious nature.

First of all, such a patient receives treatment for the underlying disease, and then the resulting stain is removed surgically. Among surgical interventions, keratoplasty with the use of donor cornea implantation is the most popular.

Treatment of white spots on the eyes with cataracts

On the early stages practice conservative methods treatments that normalize metabolism and trophism (nutrition) of the eye. On the late stages at mature cataract recommend surgical intervention. White spots can be removed both with a simple removal of the lens, and with the subsequent implantation of an intraocular lens.

What causes flickering in the eyes? The reasons may be different. This has happened at least once in a person's life, for example, when getting up abruptly from the couch. But sometimes glare appears in front of the eyes too often. They most often appear after a change in lighting or body position, and only in some cases are a manifestation of health problems. Especially if the flashes are accompanied by a headache.

Special attention should attract flashes in the eyes, which are repeated many times. Especially if it causes tinnitus, headache or dizziness, as well as disorientation in space. In this case, glare indicates the presence of pathologies.

Causes of glare before the eyes great amount. All of them indicate a violation of the CNS ( central nervous system), as a result of which there is a deterioration in blood circulation in the vessels and, accordingly, a violation of blood circulation in the brain. And this leads to problems with blood pressure and the work of some body systems.

Most common causes flicker:

The most common cause of glare is a change intracranial pressure and impaired circulation to the brain. In this case, white glare or black spots may appear before the eyes in the sun.
In connection with the change in intracranial pressure, the blood vessels of the eyes overflow and flies appear. Often bunnies and glare in the sun appear with an increase or decrease in blood pressure.

In addition to the above, there are other serious reasons the appearance of flies before the eyes, namely:

Hemorrhage in the brain. In this case, flies and bright flashes appear, which portend a loss of consciousness.
Problems with the spine. Black and white flies often indicate pathologies of the spine, because in this case nerves and blood vessels are pinched, blood outflow worsens, especially with cervical osteochondrosis. In this case, both the brain and the eyes suffer.
Avitaminosis, unbalanced diet, debilitating diets and exhaustion.
Traumatic brain injury or eye injury.
Hypotension or hypertension. With hypotension, flashing dots, darkening, glare or floating spots appear before the eyes.
Mental and emotional stress, stress and nervous breakdowns. In this state, there is a sharp change blood pressure, and therefore there is a flicker in the eyes.

Drinking alcohol and smoking.
Severe poisoning. Flashes in the eyes can appear with toxic exposure, which leads to impaired function of the organs of vision.
Diabetes mellitus in a severe stage. This disease leads to vascular damage.
Anemia. With this disease, flickering in the eyes occurs regularly.
Internal bleeding.

Flashes in the eyes may appear in pregnant women. it dangerous state so you need to consult your doctor immediately.

Often, glare and bunnies occur after overheating in the sun and may portend sunstroke. Even bright sunlight, if you look at the sun without glasses, can cause white and black spots to appear before your eyes.

Eye problems

Flickering in the eyes can occur directly due to eye diseases. How dangerous can glare and bunnies be?

If the flies do not appear at the time of physical or emotional overstrain, but regularly, then the person's condition can be critical. Problems may be in the approaching hemorrhage or retinal rupture. In this case, flashes appear constantly and become familiar to humans. You need to immediately go to the hospital so that your vision does not worsen.

Another fairly serious cause of glare is retinal detachment. In addition to the flies, there is a blurring of the image.

Flashes in the eyes, as from sunlight, can appear with such disorders of the organs of vision:

Inflammatory processes eye, inflammation of the vessels that supply the retina nutrients.
Tumor diseases which can damage the retina.
Violation of the blood circulation of the organs of vision.
Lens injury leading to retinal detachment.
Clouding of the lens and development of cataracts.
Detachment vitreous body.

Detachment or tension of the retina occurs as a result of irritation of the visual analyzer. It is significant that flickering in the eyes can acquire different shape. Glare can be in the form of black and white spots, bright flashes(bunnies), lines, zigzags and rings. As a rule, they appear for a split second. Normally, flashes or spots may appear after sleep or bright light.

What should be done with flies?

With constant flies in the eyes without medical care not to do, because you need to find out the cause of this condition. In addition to the organs of vision, all systems of the body are examined and possible serious illness.

Ophthalmoscopy, blood tests, and ultrasound are usually sufficient ( ultrasound procedure) or CT ( computed tomography) examination. According to the results, treatment is prescribed.

Flicker Prevention:

When flies appear in the eyes, it is necessary to exclude the fact of severe exhaustion of the body. You need to adhere to the rest regimen, sleep at least 8 hours and avoid stress.
It is also necessary to exclude the possibility of low, high pressure or anemia. If the cause of glare is in these violations, then it is enough to adjust the diet.
With anemia, you need to eat more meat (especially veal), liver and apples. If necessary, you can take a course of treatment with drugs containing iron.
For the prevention of flies, it is important to keep the level of sugar, cholesterol, blood pressure and hemoglobin within normal limits.
To improve the process of blood circulation and saturate the blood with oxygen, you need to do it every day. hiking. You need to walk for at least half an hour.
Carrots, herbs, nuts, fruits, blueberries and dried apricots will be very useful for the organs of vision.
To prevent eye diseases, you need to take a break after every hour of working at the computer.
In bright sunlight, it is best to wear sunglasses.

Glare and spots before the eyes very often appear with a sharp change in body position, especially after sleep. They can also indicate physical or emotional exhaustion. In this case, the flies are accompanied by a headache or dizziness.

If flashes in the eyes appear regularly, then you need to visit a doctor, they may indicate anemia, drops in blood pressure or much more. serious problems with health.

Naturally, the risk of developing increases with age. various diseases. Eyes are no exception: age cataract, retinal dystrophy ... Only regular examination an ophthalmologist allows early detection of serious eye diseases and prevention possible loss vision.

In some cases, for example, with an acute attack of glaucoma, the count goes not for days, but for hours: the sooner treatment is started, the higher the chances of restoring vision. Knowing some of the signs of eye diseases will help you to seek help from a specialist in a timely manner.

Sudden loss of vision in one eye

If you are over 60, and especially if you are nearsighted, arterial hypertension, diabetes, systemic diseases, there is a risk that the loss of vision is caused by vascular disorders - occlusion central artery retinal or thrombosis central vein retina.

In such cases, time is counted by the clock, and only timely specialized assistance will help restore vision, otherwise irreversible blindness of the affected eye occurs.

Sensation of a black curtain in front of the eyes that obscures part of the field of vision

Sensation before the eyes of a black or translucent veil from the periphery. Such a symptom is often observed with retinal detachment. The condition requires immediate hospitalization. The sooner treatment is started, the greater the chance of vision recovery.

Sharp pain in the eye, redness, blurred vision, may be nausea, vomiting

These could be signs acute attack angle-closure glaucoma. Intraocular pressure rises sharply, which can lead to damage optic nerve. Shown immediate decline intraocular pressure up to surgical treatment. Don't wait until the pain will pass. Seek immediate medical attention.

Gradual or abrupt narrowing of the field of vision

A gradual or abrupt narrowing of the field of vision, resulting in the ability to see only what is located directly in front of you - the so-called "tubular" vision. Perhaps you have glaucoma, one of the main signs of which is a narrowing of the field of vision as a result of damage to the optic nerve.

Without appropriate conservative or surgical treatment, vision will deteriorate. terminal stage glaucoma is total loss vision. Possible severe pain, which do not stop even after the operation and require, ultimately, the removal of the eye.

Gradual deterioration of central vision, blurring, distortion of the image (straight lines appear wavy, curved)

These may be symptoms of macular degeneration - a degenerative disease of the central region of the retina - the macula, which plays the most important role in providing vision. The incidence increases sharply with age.

Without supportive treatment, vision gradually deteriorates, glasses do not help. There are currently various options treatments that are applied depending on the form of macular degeneration.

Also, a sudden decrease in vision may be due to a macular retinal tear, i.e. retinal break in the central zone. It is necessary to immediately contact an ophthalmologist to clarify the diagnosis, since a retinal rupture in the macular region, if treatment is not started on time, leads to irreversible loss of vision.

Fog before the eyes, reduced brightness and contrast

These symptoms can be caused by a developing cataract - clouding of the lens. Vision deteriorates gradually, eventually declining to the ability to distinguish only light. In most cases, urgent medical care is not required, at a certain stage, planned surgical treatment is carried out - cataract removal with implantation of an artificial lens.

However, periodic observation by an ophthalmologist is recommended, since in some cases cataracts may be accompanied by an increase in intraocular pressure, which requires urgent surgical treatment. In addition, as the cataract develops, the lens becomes more and more hard and increases in size, which can complicate the operation to remove it, so you need to visit a specialist regularly to determine optimal time for surgical treatment.

Dark spots, floaters, fog, or a blurry feeling before the eyes

If you have diabetes, these may be signs of diabetic retinopathy, a retinal damage caused by diabetes. As diabetes progresses or decompensates, the risk of eye complications increases dramatically.

Regular visits to the ophthalmologist for examination eye day, since changes in the vessels and the retina itself, hemorrhages in the retina and vitreous body can cause irreversible loss of vision.

The ophthalmologist will prescribe you a therapy that is necessary specifically for the eyes, which may not only consist in taking certain medications, it is often required laser treatment other treatments may also be used. Timely laser coagulation of the retina is the only way preservation of vision in diabetes mellitus.

Burning sensation, sand in the eyes, sensation of a foreign body, lacrimation, or, conversely, a feeling of dryness

Such complaints occur with dry eye syndrome, the frequency and extent of which increase with age. Usually we are talking primarily about discomfort and deterioration in the quality of life, rather than about any danger to the eyes.

However, severe dry eye syndrome can cause some serious pathological conditions. Your ophthalmologist will tell you more about dry eye syndrome, necessary examination, will recommend which moisturizing drops are best for you to use.

Ghosting

Double vision when looking with one or two eyes can be caused by many reasons, both from the side of the eyes and other organs: intoxication, vascular disorders diseases of the nervous system, endocrine pathology. If double vision suddenly appears, immediately consult a general practitioner, ophthalmologist, neurologist and endocrinologist.

Floaters before the eyes

Usually floating spots, threads, "spiders" before the eyes are explained by the destruction of the vitreous body. This is a non-hazardous condition associated with age-related changes structures of the vitreous body - a transparent gel-like content that fills the eyeball. With age, the vitreous body becomes less dense, liquefies, and does not adhere as tightly to the retina as before, its fibers stick together, lose transparency, casting a shadow on the retina and being perceived as defects in our field of vision.

Such floating opacities are clearly visible on a white background: snow, a sheet of paper. The destruction of the vitreous body can lead to: arterial hypertension, cervical osteochondrosis, diabetes mellitus, head injuries, eye and nose injuries, etc.

However, an unexpected spot in front of the eyes, a “curtain” can be caused by a serious pathology that requires emergency treatment- for example, hemorrhages in the retina or vitreous. If symptoms occur suddenly, on the same day, contact an ophthalmologist immediately.

If you have any previously absent visual symptoms, it is better to immediately contact a specialist. If vision has deteriorated sharply in a few hours or days, pain is bothering you, do not waste time. Even if it is not possible to consult your ophthalmologist, you can go to the emergency room eye care that are in every city in multidisciplinary hospitals or eye hospitals.

AT last resort Many opticians are visited by experienced ophthalmologists who will conduct the minimum necessary examination and give recommendations for further actions.

Black dots in the eyes are a common phenomenon that most of the world's population has encountered at least once.

They can have a different origin and are caused by both very minor disorders and serious pathologies of the eye.

Sometimes they are completely unobtrusive and quickly disappear, but there are times when they fill a significant part of the field of view and interfere with the normal examination of surrounding objects.

What it is?

Between the lens and the retina is the vitreous body of the eye. This is the environment that most from the volume of the organ of vision, it is filled with liquid.

When the eyes experience negative impacts and their cells die off, they accumulate in the vitreous body.

When there are many such cells, their formations become large enough to cast a shadow on the retina. We see this shadow as black dots that move with our eyes.

Especially often, such flies appear when looking at bright light sources, since they illuminate cell formations more strongly.

The vitreous body can also undergo internal degradation. In this case, its tissues will be destroyed with the formation of shreds that are impenetrable to light.

The reasons

Such processes can be provoked by both minor disturbances in the functioning of the body, and serious pathologies. Among the variety of reasons are the following:

Mechanical damage to the eye. Injuries and burns contribute to cell death.
Diabetic retinopathy, in which the retina detaches from the vitreous body.
Presence in the eye foreign bodies and dirt.
Age after 55 years. Degradation of eye tissues by this age is inevitable. The appearance of flies, as a rule, is accompanied by a general degradation of vision.
Avitaminosis. Lack of nutrition of the tissues of the eye can lead to the death of some of them.
Overwork and overexertion, especially long work at computer.
Circulatory problems caused by disruption of the vessels of the neck and head, as well as alcohol consumption and smoking. Bursting blood vessels throw out blood clots that can accumulate in the vitreous body and darken it.
Damage to the eye tissue by pathogenic viruses, bacteria and fungi.
Destruction of the vitreous body can be separate, independent disease due to genetic predisposition.

Symptoms

Black formations in the eyes may have different manifestations. They can be filamentous and granular. In the first case, black lines appear in the field of view, which are woven into entire networks.

In the second case, the forms of black formations are limited to dots. They differ in that dots occur, as a rule, due to foreign bodies getting into the eyes, while the cobweb and mesh are characteristic of the internal degradation of the vitreous body.

One of the main features of black dots in the eyes is that if you turn your head quickly, then the dots will follow the gaze with a delay. This is due to the greater inertia of the liquid medium of the vitreous body.

In case of serious pathologies, the points may be accompanied by flashes in the eyes and other visual disturbances. Older people are often faced with the fact that there are so many flies that it makes it difficult to see the outlines of objects.

Treatment and prevention

There are two surgical techniques aimed at eliminating defects of the vitreous body. The first is called a vitrectomy. This is very complicated operation, the essence of which is the complete or partial replacement of the vitreous body with a substance similar in composition.

Schematically, it looks like this:

It is used only in cases where dots in the eyes seriously reduce the ability to see.

The second technique is less radical, it is called vitreosilis. This is a procedure for laser fragmentation of shreds and other large formations in the vitreous body.

The laser energy pulverizes them to a state of many elements too small to cast a shadow on the retina, as a result, the black dots in front of the eyes disappear.

The operation is quite expensive, and also not always effective in the fight against small formations.

In most cases, when there are few points, and they appear infrequently, standard local therapy using drops such as Emoxipin, Taufon, Wobenzym is sufficient.

It will not be superfluous to struggle with systemic causes the appearance of points in the eyes: normalization of blood circulation, restoration of the health of blood vessels (especially those in the neck), consumption of vitamins and minerals in enough. With this treatment, the points will pass quickly, within a month.

Application possible folk remedies aimed at eliminating one or another pathology that causes flies before the eyes. But to establish their cause in this case should be unambiguous.

A visit to the doctor is mandatory if the points occur after a head injury, eye damage or burns, after concomitant painful sensations with impaired vision. In these cases, black dots with more likely are symptoms of a more serious disease.

To avoid the development of destruction of the vitreous body, do not allow foreign bodies to enter the eye, and if it occurs, do not rub it into the cornea, but rinse the eye with water.

Strengthen your immune system to avoid infection of the eye by fungus or bacteria. Do not drink alcohol, do not smoke. Try to give the body at least the minimum physical activity. Do not overstrain your eyes, follow the doctor's prescription for wearing glasses for farsightedness or nearsightedness.

Vitamins are essential for eye health. Here are some of the most popular:

Results

The detection of one or more black dots in front of the eyes is not always a reason for panic, as it can be a symptom of simple eye fatigue or a small foreign body getting there.

But big number blackheads that don't disappear for a long time, speaks of more serious pathologies in the vitreous body, for example, the death of its tissues or its detachment from the retina.

In such a case, it is necessary surgical intervention, which consists in laser crushing of dead tissues or even a complete replacement of the vitreous body.

In order not to bring the eyes to such a state, it is necessary to avoid overworking them, mechanical damage and consume optimal amount vitamins.

If suddenly your vision has decreased due to the appearance of a spot in the eye, then you need to find out the cause of this event. The spot may be a site of inflammation and have a red color, sometimes it is manifested by floating flies. In some cases, there is no cause for concern and the appearance of spots is associated with the usual overexertion and fatigue, in which it is useful to give the eyes a rest and support them with a vitamin course. But in other cases, serious medical intervention up to surgical treatment.

Red spot in the eye

The appearance of a red spot on the eye is usually associated with damage to the capillaries. These small vessels are located in in large numbers inside the eye and can expand under the action various factors. As a result, the whites of the eyes become red.

The appearance of red spots on the eyes is not always accompanied by pain, but outwardly they are always very noticeable. Not everyone will like the fact that the eyes have an inflamed and tired look due to the peculiar coloring of the proteins. Most typical cause such changes is eye fatigue due to lack of sleep, long work at the computer or watching TV.

To quickly relieve symptoms of fatigue, you can use vasoconstrictors, which include Vizin, Sofradex, Murin. It should be noted that these drops are not suitable for long-term use, as this causes excessive dryness of the mucous membrane of the eye. Such changes in themselves can cause redness and irritation of the eyes.

In addition to fatigue, redness of the eyes can be caused by inflammatory and infectious processes. Usually, along with a change in eye color, itching occurs, purulent discharge, decreased visual acuity. In this case, only a doctor can correctly determine the tactics of treatment, so you should not start an infection, it is better to seek help from an ophthalmologist.

Sometimes a red spot on the sclera of the eye appears when it is ruptured blood vessel. A feature of this condition is a unilateral lesion. Usually the surface capillary is damaged as a result of physical tension, for example, when coughing or lifting heavy objects, or when exposed to external factors(injury, temperature drop, strong wind). Sometimes the capillary becomes more fragile after taking some medicines. At sharp rise systemic pressure may develop subconjunctival hemorrhage, which also leads to the appearance of red spots on the whites of the eyes. Among the reasons for the appearance of such spots, blood diseases and systemic infections should be listed.

Dark spot in the eye

When a floating dark spot appears before the eyes, we can talk about damage to the substance of the vitreous body, which is accompanied by the destruction of the gel-like structure. Most often, these spots can be noticed when looking at a light background, such as a ceiling, a piece of paper, or the sky. As the eye moves, the flies also move, giving the appearance that they are swimming inside. This often causes discomfort.

Typically, these flies bother elderly patients or people suffering from myopia.

If available similar symptoms, then it is highly advisable to see a doctor, as there may be quite serious pathologies up to retinal detachment. If a retinal tear is diagnosed, then the situation can be corrected by laser coagulation changed area.

Some signs are a poor prognostic factor, so when they appear, a visit to the optometrist should not be postponed:

A sudden decrease in visual acuity, which is accompanied by the appearance of lightning, flashes during fixation of the gaze on a solid background.
A significant increase in the number of floating spots.
The emergence of the so-called curtain. In this case, the entire field of view (or a significant part of it) is affected by this phenomenon.

If the patient complains about the appearance dark spots before the eyes, then most often use resolving therapy. These drugs stimulate metabolism in the vitreous substance, and also help to restore the lack essential substances. Such drugs include Wobenzym tablets, Emoxipin drops, as well as a number of vitamin complexes for eyes. Supplement drug treatment possible with the help of physiotherapy. AT severe cases eye surgery is required.

Blind spot of the eye

The blind spot is an area of physiological lack of vision, that is, it is present in everyone, even absolutely healthy patient. In this area of the retina, light-perceiving receptors are completely absent, however, due to the presence of two eyes, the blind spot area remains unnoticed. This is due to the fact that the image is completed due to the opposite eyeball.

The structure of the retina is not uniform. Thus, the highest concentration of receptors is found in the zone of the central fovea of the eye, which is responsible for clear central vision. Around the fossa is a yellow spot, which also has high concentration receptors, especially cones (responsible for color perception). In the peripheral zone, the number of cones decreases, but at the same time the number of rods increases. This allows a person to navigate at dusk and perceive the shape of objects.

In the blind spot zone, these receptors are absent, therefore, no information is perceived by this area of the retina, and the rays that fall on this part are not transmitted to higher structures. The blind spot is located near yellow spot and its localization is symmetrical on both sides. This phenomenon allowed the king Louis XIV due to a certain focusing of the gaze, to see people in front of him without heads.
