Dizziness is a veil before the eyes of the cause. Why does the veil appear before the eyes. The main causes of the development of the veil before the eyes and the diseases in which this disease occurs

Good vision is taken for granted, so people often do not focus on the various manifestations of the disorder. But even the slightest deviation can indicate some serious violation in the body. One of these manifestations is the veil before the eyes.

It is believed that this symptom indicates a partial or complete detachment of the retina, which is responsible for projecting a visible image.

The veil before the eyes can appear due to various factors. But possible reasons include:

In some cases, a veil before the eyes and white flies can appear immediately after waking up when getting up abruptly from a bed or sofa, when sitting at a computer for a long time, or when being in a stuffy room. All this can happen as a result of a sharp jump in pressure. Often this condition occurs in pregnant women or in the elderly.

Diagnosis and detection of the presence of a veil before the eyes

If there is such a sign as a veil before the eyes, the patient is advised to consult an ophthalmologist. He will prescribe a special examination, which includes the following actions.

Ophthalmoscopy to establish the state of the retina.

Tonometry for measuring intraocular pressure.

Ultrasound diagnostics.

Biomicroscopy, which is performed using a slit lamp.

At the doctor's appointment, the patient needs to find out about a number of questions.

Why did the veil appear before the eyes?

What to do if it reappears?

When should you come back for a follow-up appointment?

How to cure this disease?

Healing shrouds before the eyes

Treatment of the veil before the eyes directly depends on the possible cause that led to the onset of the disease.

If the turbidity has arisen due to damage to the cornea of the eye with scar tissue, then the patient is transplanted.
When diagnosing cataracts of an advanced stage, the patient is removed the clouded lens and put a new lens. And if the disease is at the initial stage, then the doctor prescribes vitamin eye drops to drip into the eyes.

With the appearance of glaucoma, the patient must be given first aid, because there is a high probability of completely losing sight.

When exfoliating the retina, the patient undergoes laser coagulation. In medicine, it is usually called the biological "welding" of the retina. The fluid that has accumulated under the eye tissues is absorbed within a few days after laser manipulations. The duration of the procedure is from thirty to sixty minutes.

Preventive measures to eliminate the veil before the eyes

These measures are aimed at preventing the possible causes of the appearance of a veil before the eyes. Special recommendations have been made which include:

In continuous pressure measurement. and its control.

In continuous monitoring of blood sugar levels to exclude vascular lesions of the retina.

In following the hygienic treatment of the eyes to prevent infection.

Upon reaching the age of forty, patients are advised to visit an ophthalmologist more often, because it is at this age that the risk of cataracts and glaucoma increases.

In observance of the regime of work and rest. This applies not only to adults, but also to children. Sitting at the computer and watching TV should be controlled. Be sure to take a break for twenty to thirty minutes.

In observance of proper nutrition and the rejection of bad habits.

In the constant implementation of walks in the fresh air.

In moderate physical activity. It will be great if the patient takes up some kind of sport. It does not matter that it will be swimming or jogging around the house, the main thing is that everything is done for the soul and for the body.

A white veil before the eyes or the appearance of flies are among the symptoms that signal the onset of some kind of disease. Therefore, you should not ignore them and postpone a visit to the doctor, because this can lead to complete loss of vision. The treatment process is carried out only after establishing the true cause using diagnostic methods, and the outcome will depend on the patient himself.

It happens that the picture before your eyes suddenly blurs. Colors become less bright, objects lose their sharpness, the surrounding world is immersed in "fog". A veil in the eyes is a fairly common phenomenon, but, alas, not harmless. Thus, the body signals about serious ailments that can lead to loss of vision. Especially dangerous are the states when the veil does not look like a thin film, but like cloudy, dark or red glass. Such a symptom warns of a violation of the transparency of the eye media or problems of recognition of the received image by the occipital cortex of the brain.

Where to go

If you have a veil in your eyes, blurry vision, then first of all you need to contact an ophthalmologist. It is this specialist who should conduct the initial diagnosis and determine the cause of the disease. If the ophthalmologist does not find violations, then a consultation with a neurologist will be required. The main thing is not to delay the appeal, because you can lose time.

White veil. Cataract

A white veil in the eyes is most often a symptom of eye diseases. In many cases, this can be a unilateral process affecting only one eye. Often, patients with such complaints are diagnosed with a cataract, that is, a violation of the transparency of the lens.

The lens is a "biological lens" created by nature to refract light. It is located on the ligaments inside the eye and does not have its own blood supply. The lens is nourished by intraocular fluid. At some point, as a result of natural aging or metabolic disorders, the transparency of the lens deteriorates. At this moment, a veil appears in the eyes, blurry vision, objects begin to double, obsessive flies appear before the eyes, the picture turns yellowish, it becomes more difficult to read, write and work with small objects.

A person does not feel pain during a cataract, this creates a deceptive feeling that nothing supernatural is happening. However, the quality of life gradually deteriorates, twilight vision weakens, lacrimation begins in bright light, it is more difficult to read, more powerful lamps are required, a halo becomes visible around light sources, and patients with farsightedness gradually stop using glasses.

Glaucoma

Permanent veil in the eyes can be This disease is associated with a steady increase in intraocular pressure, as a result of which intraocular hypertension begins, since the unhindered outflow of intraocular fluid is disturbed. The process is very dangerous, it can lead not only to but also to its complete irreversible loss. Suffice it to say that of the total number of blind people, 15% lost their sight as a result of glaucoma.

Glaucoma is classified into two forms:

Open angle. This means that the outflow of fluid in the anterior eye chamber, located in front of the lens, has been disturbed. Such a pathology is considered less dangerous, since it develops gradually, leaving time to take action. With the open form of glaucoma, the angle of view gradually decreases (with a separate speed for each eye), a veil appears in the eyes and iridescent circles in front of them. Headaches become more frequent, twilight vision worsens.
Closed angle. This means that the blockage of the outflow occurred in the area of the junction of the iris and cornea. In this place, the main exchange of fluids of the anterior and posterior eye chambers occurs. At the first stage, the disease does not cause discomfort. The reasons for the deterioration of the patient's vision are not clear. Then an acute attack occurs, during which the outflow of fluid is completely blocked. There is a sharp pain in the head and eye, which is often confused with a migraine. Vision rapidly falls, a veil appears, dizziness and vomiting begin. The eye, in which an attack of angle-closure glaucoma has occurred, turns red and becomes dense. Nature has given very little time to eliminate the blockage of the outflow. Sometimes it's only 3-4 hours. Then vision is lost forever.

Optic neuritis

As already mentioned, if there is a veil in the eyes, the reasons do not always lie in the field of ophthalmology. If, as a result of the inflammatory process, the optic nerve reduces sensitivity, then the image from the retina does not reach the brain. This problem is called "optic neuritis" and is treated by a neurologist. In addition to inflammation, the cause of neuritis can be a demyelinating disease (destruction of the myelin sheath of neurons by the immune system).

Veil in the eyes, the causes of which are optic neuritis, may be accompanied by partial or complete blindness. The severity of the disease depends on the degree of damage to the diameter of the nerve.

A few more reasons for the white veil

In addition to the above diseases, the appearance of a white veil before the eyes can be caused by:

occlusion of the central artery in the retina;
corneal disease;
senile farsightedness;
brain tumor;
uncontrolled intake of glucocorticoids, antidepressants, contraceptives;

Dark shroud. Migraine

The veil before the eyes may not be whitish, but dark. This symptom is characteristic of several diseases, one of which is migraine. In this case, they are neurological in nature and are accompanied by excruciating unilateral headache. Most often, patients have a genetic predisposition to migraine. Attacks of pain cause not only blurred vision, but also dizziness, nausea, speech disorders, and sometimes even hallucinations.

Retinal disinsertion

This is a problem associated with detachment of the inner lining of the eye containing photoreceptor cells. The retina at the place of detachment does not receive nutrition from the choroid, and dries out. The process is gradual, it begins with light flashes, zigzag lightning and black flies. Further, a partial or complete dark veil appears in the eyes. What to do in this case? Urgently run to the doctor! Minor delaminations can be "soldered" without serious consequences. But if the process is running, then the shrunken retina cannot be fixed. Vision will be lost.

Red veil in the eyes

And another dangerous symptom is a red veil. This means that blood has poured into the vitreous body or the space surrounding it, that is, hemophthalmos has occurred. The veil in the eyes in this case may indicate a complication of diabetes mellitus, the development of atherosclerosis, hypertension, or hemophthalmos can also occur due to retinal detachment and eye injuries of varying degrees of complexity.

A red veil is accompanied by blurred vision, the appearance of shadows, flies or stripes. If the hemorrhage occurred as a result of glaucoma or trauma, then pain will become an additional symptom.

Why is it important to correctly describe the accompanying symptoms?

To make a correct diagnosis, it is not enough for a doctor to hear from the patient: “I have a veil in my eyes in the morning.” To understand in which direction to move, the description of the accompanying symptoms will help. So, for example, if the appearance of a veil is accompanied by weakness, then it can be low blood pressure, anemia, VSD, hypertensive crisis. If chaotically moving flies appear along with the veil, then cataracts, hemophthalmos, retinal detachment, brain tumor (in the back of the head), migraine and others are added to the list of possible diseases. If dizziness is added to the listed symptoms, then it can be a stroke, internal bleeding, poisoning, and so on.

Since there are many variants of diseases, it is necessary to describe your condition to the doctor as accurately as possible.

Diagnostic examination

Since, first of all, patients turn to an ophthalmologist, they will be examined using a slit lamp, eye tonometry (measurement of intraocular pressure), instrumental examination of the fundus, and ultrasound. If the ophthalmologist does not detect pathology, then the patient is redirected to a neurologist.

The neurologist determines reflexes and sensitivity, prescribes vascular dopplerography (head, neck), MRI (head, neck).

Veil in the eyes: treatment

There are many factors that lead to vision problems. And every disease, a symptom of which could be a veil in the eyes, requires appropriate treatment. So, for example, in case of retinal detachment, drug therapy is prescribed to improve vascular patency and metabolism. Additionally, laser coagulation (soldering) of the retina is performed.

With cataracts, in its initial stage, vitamins and nutrients are prescribed for instillation into the eyes. In later stages, an operation is performed to replace the lens.

Glaucoma is treated with drugs that reduce the pressure inside the eye. If necessary, the outflow is restored by surgery.

The main thing that the patient must understand is that the doctor needs time to take measures to preserve his vision. You can not ignore the veil in the eyes, especially if it is often repeated or held steady.

The veil in the eyes is an unpleasant symptom that can appear with a variety of diseases of the organs of vision and the cardiovascular system. The appearance of a veil may be accompanied by a loss of color and clarity of the image. Pathology can be of different intensity and duration. These are diagnostic signs that help the doctor make a diagnosis. If the veil bothers you throughout the day, but does not interfere with distinguishing objects and colors, then it seems safe. In fact, this symptom warns of the development of a chronic disease. Which one - depends on what symptoms accompany the appearance of a veil.

In more than 30% of cases, the cause of the pathology is a change in the retina. This is the part of the eye on which the image received by the visual analyzer is converted into a nerve impulse. Therefore, discomfort cannot be ignored - it is necessary to undergo an examination and find out the exact cause. Most ophthalmic diseases are easier to correct at an early stage of development.

The reasons

In the vast majority of cases, the causes lie in defects in the organ of vision, much less often the veil occurs due to cardiovascular or nervous diseases.

List of diseases accompanied by similar symptoms:

Violation of blood circulation in the vessels of the retina.
This is one of the most common ophthalmic pathologies. It is characterized by the fact that the veil appears for a while and then disappears. Its occurrence is sometimes accompanied by a number of other unpleasant symptoms: headache and weakness. Very often, the blood supply to the retina worsens against the background of a more serious disease: hypertension, thromboembolism, diabetes mellitus, or after an acute circulatory disorder.
Cataract.
Another disease that ophthalmologists face daily. Cataract is a slowly progressive disease, so the veil does not appear immediately. Every month it gets tighter. This is due to the gradual clouding of the lens. Cataracts are successfully treated: modern techniques make it possible to replace the lens and restore vision even in the case of an advanced disease.
Glaucoma.
An attack of this disease can provoke a sharp rise in intraocular pressure. Visual impairment is accompanied by pain in the eye and in the head.
Diseases of the cornea.
The cornea is quite difficult to damage, so most often the veil appears on the background of inflammation or after a serious injury. Sometimes the corneal layer is destroyed as a result of sluggish dystrophy. In all cases, the appearance of a veil is associated with clouding of the cornea - transparency decreases and less light reaches the retina.
Myopia.
The veil accompanies only such a stage of the disease, in which the normal configuration of the eyeball is disturbed. In addition to blurry vision, many other disorders appear.
Retinal detachment or retinal dystrophy.
They develop after an eye injury, less often against the background of chronic diseases, for example, macular degeneration. Diseases of the endocrine glands, diabetes mellitus and rheumatoid arthritis, as well as all diseases associated with circulatory disorders, lead to retinal detachment. Sometimes dystrophy is congenital.

Not always the cause is an eye disease. The veil before the eyes also arises against the background of a concussion. Therefore, when receiving a traumatic brain injury, the first thing to do is to go to the emergency room, and only then consult an ophthalmologist.

Associated symptoms

Very rarely, the veil appears without accompanying symptoms that will help to recognize which disease caused the ailment. The clinical picture of these diseases is accompanied by symptoms:

Glaucoma:

Sharp pain in the eye and in the head from the side of the affected eye.
Vision deteriorates sharply, sometimes so much that the patient does not see the outlines of objects, he is only able to distinguish light.
A veil appears in front of the eye.
Nausea, often leading to vomiting.
Redness of the eye.

Corneal lesion:

Lachrymation that does not stop for a long time.
Sensation of a foreign body in the eye.
Cutting in eyes, aggravated by light.
Decreased visual acuity.

Pain that occurs in only one part of the head.
The pain is throbbing or aching.
Severe discomfort with loud noises, strong smells, or bright lights.
Relief of pain in darkness and silence.
Nausea.

The appearance of a veil before the eyes may be accompanied by light flashes, spastic headache, glare. If you experience unpleasant symptoms, you should consult an ophthalmologist. Even if you know what exactly provoked the attack. It is impossible to choose an effective treatment on your own, especially for diseases such as cataracts and glaucoma.

Dangerous symptoms

There are a number of signs that indicate the development of a life-threatening disease. When they appear, you should consult a doctor without delay:

A sharp increase in body temperature.
Numbness of one hand.
Enduring weakness.
The emergence of photophobia.
The veil is accompanied by "flies" before the eyes, which do not disappear for several minutes.

Almost all of these symptoms are characteristic of an acute circulatory disorder or an acute infectious process.

Diagnostics

If a patient turns to a specialist with complaints of blurry vision, then the ophthalmologist will perform several basic diagnostic measures:

visual eye examination
retinal examination
intraocular pressure measurement
examination with a slit lamp or ophthalmoscope

Based on the results of the initial examination, it will become clear what additional examinations need to be completed.

If the appearance of unpleasant symptoms is caused by an injury, then the doctor will definitely refer you to a traumatologist or neurologist, since the first step is to exclude fractures and serious brain damage.

In diseases such as glaucoma, cataracts, retinal detachment, surgery is often required. Before it, you will have to undergo additional examinations and pass standard tests.

Treatment

Treatment depends on what disease led to the appearance of the veil. Therapy begins only after the final diagnosis is made.

If the cause was a cataract, then the veil develops only on one eye and is associated with clouding of the lens. The treatment is aimed at restoring transparency - this can only be done with the help of surgery to replace it. It is impossible to cure a clouded lens, so there is no point in conservative therapy.

Very often, patients are prescribed various drugs. This is a supportive treatment that includes vitamin and mineral complexes, vascular strengthening agents, and eye drops that help to cope with unpleasant symptoms. The modern treatment regimen involves laser surgery, which is less painful than traditional surgery. During the procedure, an implant is placed in place of your lens.

An acute attack of glaucoma is easy to recognize on your own. For those who have a tendency to this disease, the attending physician can give advice on which drugs should be used during an attack. In the case of acute glaucoma, it is important to contact an ophthalmologist as soon as possible. If the disease progresses, then the treatment is only surgical.

For any retinal lesions, complex therapy is required, aimed at both preventing further vascular changes and treating metabolic disorders that led to the development of the disease. If a retinal detachment has occurred, then laser surgery is required. The soldering is performed using a laser beam. This is one of the simplest procedures - it is performed on an outpatient basis, takes no more than an hour, and is completely painless. In eight cases out of ten, vision is restored in full, in the remaining cases, a lasting improvement is achieved.

Every person takes good vision for granted, therefore, it does not take into account very serious disorders of the visual system.

But at first glance, not disturbing deviations can portend the onset of a serious illness. One of these deviations is the veil before the eyes.

It is believed that such a visual disorder is associated with partial or complete detachment of the retina, which is responsible for the projection of the visible image.

In this regard, any deformations or changes in the retina reduce visual acuity or even complete blindness of a person.

The main causes of the development of the veil before the eyes and the diseases in which this disease occurs

A veil before the eyes can be provoked by the following situations and diseases.

Vascular diseases. As a rule, with such ailments, complaints about the veil before the eyes are intermittent and are often associated with impaired blood supply to the retinal vessels. Visual impairment occurs with the development of diseases such as hypotension, hypertension, anemia, angiospasm of retinal vessels, vegetative-vascular dystonia. In addition to the veil before the eyes, these diseases are manifested by headache, general weakness. Having eliminated the cause of the veil, the condition returns to normal, however, in such cases, the patient will not need special ophthalmic care.
Cataract development. As a result of this disease, fogging increases gradually, often over several years. This happens due to the clouding of the biological lens - the lens. Therapy in this case consists in the use of special eye drops containing vitamins (Katachrom, Quinax, Taufon, Catalin, etc.), but they can slow down the formation of a veil before the eyes, and not get rid of it. Unfortunately, in this case, one cannot do without surgery - it is imperative to replace the clouded lens with an artificial lens.
Glaucoma attack. Complaints about the veil before the eyes appear sharply, and often this condition is accompanied by pain in the eye and headache on the side of the lesion, as well as iridescent circles. In such a situation, urgent help from an ophthalmologist is needed, it is necessary to take a diuretic (a diuretic - furosemide) inside and drip Pilocarpine into the eye, take an analgesic. In the absence of a positive effect, the patient is shown surgical treatment.
Impaired patency of retinal vessels. Such symptoms increase quite quickly, up to complete blindness. This condition develops against the background of the following diseases: atherosclerosis, hypertension, diabetes mellitus, etc. Depending on retinal vein thrombosis or arterial embolism, therapy is prescribed exclusively in an ophthalmological hospital.
Diseases of the cornea. The cornea is the light-refracting and light-conducting system of the eye, which, with the development of pathologies, loses its transparency and light rays cease to fall on the retina. This process often proceeds at lightning speed, treatment is determined only by an ophthalmologist.

Among the cause-and-effect relationships of the appearance of a veil before the eyes, there are:

Diabetes. This disease is one of the strongest provocateurs of retinal detachment. With the development of this disease, very fragile blood vessels grow in the patient's eye, they poorly nourish the retina and burst easily. Such symptoms often lead to tissue degeneration, and the blood that flows from a burst vessel can provoke retinal detachment.
retinal dystrophy. This is a common cause of retinal detachment and can occur with eye trauma, adrenal disease, rheumatoid arthritis, thyroid abnormalities, and other diseases.

The retina becomes thinner in two cases:

with the development of myopia(since with this deviation the shape of the eyeball changes, because of this, places are formed where the retina is stretched and deformed from the inside),
with insufficient nutrition of the tissues of the eye(some diseases of the cardiovascular blood flow lead to insufficient blood flow to the organs of vision).

In those places where the retina has thinned, tears and cracks appear, blood or the vitreous body of the eye (a gel-like substance that fills the eye) flows into them.

Moisture seeps through the cracks in the retina and lifts it - this is how detachment occurs. At the beginning of the detachment, the patient does not feel discomfort, so it is necessary to visit an ophthalmologist once a year for a consultation.

Biological "welding" of the retina

This is what doctors call a painless procedure in which a laser beam is pointed at the retina and, as it were, “welded” exfoliated tissues. The fluid that has accumulated under the tissues of the eye is absorbed some time after the operation. Such an operation lasts from 30 minutes to 1 hour in a hospital. In 80% of cases, after such an intervention, vision is restored by 98%.

It must be remembered that retinal detachment is a disease that progresses and if it is ignored, then complete blindness will certainly come.

Diagnosis of the veil before the eyes

Diagnostic measures for clouding in the eyes are carried out using the following studies:

ophthalmological examination by a specialist to determine the condition of the retina,
eye tonometry (or measurement of intraocular pressure),
ultrasound diagnostics,
biomicroscopy (examination with a slit lamp).

Treatment

Treatment of the veil before the eyes directly depends on the underlying disease that caused the clouding. Let's take a look at some of the treatments.

With extensive damage to the cornea of the eye with scar tissue, the patient may be shown its transplantation.
In cataracts, the removal of the lens of the eye and the implantation of an intraocular optical lens are effective.
In acute glaucoma, the patient is given emergency care, because there is a risk of loss of vision.
At the initial stage of a cataract, in order to slow down the pathological process, vitamins are instilled into the diseased eye, and with a mature cataract, only surgical treatment is indicated.
The affected retina is treated with metabolic and vascular therapy, as well as laser coagulation, which helps prevent retinal detachment.

Prevention

Prevention of clouding in the eyes is aimed at preventing the possible causes of its occurrence. In this regard, the main recommendations are as follows:

continuous measurement of blood pressure (arterial blood pressure),
constant monitoring of blood sugar levels (to exclude vascular damage to the retina),
hygiene (to prevent infection of the visual organs),
after 40 years, it is recommended to constantly and regularly be examined by an ophthalmologist (it is in adulthood that the risk of glaucoma and cataracts increases).

It should also be noted that the symptom of a veil before the eyes as an ophthalmic disease can occur both with damage to the light-conducting and with damage to the light-perceiving part of the visual organ.

Treatment is carried out only after establishing a complete and accurate picture of the disease with the help of diagnostics, and after that both conservative and operable treatment is prescribed.

The veil before the eyes is a sign of illness or a dangerous condition. Some patients see a white fog, others seem to look into the darkness, periodically noticing flashes. A cloudy veil greatly blurs vision, a transparent one reduces its clarity.

Possible reasons

A white veil before the eyes may be accompanied by:

migraine;
flashing flies;
speech disorder.

To identify the exact cause of the symptom, it is necessary to be examined by an ophthalmologist, neurologist, endocrinologist. Veil may indicate disorders of the SNS. Flashes of light are a sign of retinal detachment. This disease requires surgical intervention. If one of these symptoms is detected, you should contact an ophthalmologist. The doctor will diagnose and voice the alleged causes. If the organs of vision are in order, the doctor will refer to other specialized specialists. The treatment of a veil depends on the cause of its occurrence.

Learn more about diseases and dangerous conditions

Why does the veil appear and disappear. It is often associated with an ophthalmic disease. The disease covers one or both eyes. There are many causes of white fog before the eyes.

age cataract. It is associated with the aging process. With such a disease, the lens becomes cloudy, due to which visual functions are impaired. The lens is a biological lens responsible for the clarity of the image. Age-related cataracts affect people over the age of 55. The disease is manifested not only by a veil, but also by the flickering of flies, while the patient sees objects forked. It seems to him that they have a yellow tint. A cataract is not accompanied by pain, but a person does not see well in the dark. In bright light, lacrimation occurs. A patient diagnosed with a cataract cannot see the light source. It seems as if there is a halo in the distance.
Glaucoma disease. One of the most dangerous, can lead to loss of vision. It is characterized by an increase in pressure inside the eye, as a result, a person loses sight. The disease occurs against the background of intraocular hypertension. There are two forms of glaucoma: open-angle and closed-angle. The first is less dangerous, the second can lead to blindness. With open-angle glaucoma, vision deteriorates gradually. The patient sees a veil or circles resembling a rainbow. Glaucoma is accompanied by headache. The danger of the closed-angle form is that it is asymptomatic. The patient goes to the doctor in the later stages, when a veil appears before the eyes and a headache occurs. Symptoms of angle-closure glaucoma: veil and a sharp drop in vision.
Violations of the functions of the central vein of the retina. The disease occurs when the outflow of blood is disturbed. Another factor is eye swelling. Pathologies are prone to people who have increased intraocular pressure or inflamed tissue located near the vessel. Violation of the patency of the central vein may be associated with diabetes mellitus. With such an ophthalmic disease, a veil appears. Periodically, the patient sees black spots.
Occlusion of retinal vessels. Pathology is associated with blockage or spasm of small veins. Another possible reason is the deposition of calcifications. Occlusion of retinal vessels is prone to people who have atherosclerosis, diabetes, heart disease. The patient has a veil in front of one eye. At first, he feels disturbing symptoms, then a fog appears, accompanied by flashes of light. Some temporarily lose their sight.
Diseases of the cornea. The veil appears if keratitis, erosion or corneal ulcer progress. With such ailments, the transparency of the organ of vision is disturbed, respectively, fog arises. Depending on the nature of the disease, the patient may have tears. The above ailments are characterized by migraine, photophobia, headache, decreased visual acuity.
Age-related farsightedness. Pathology is associated with natural changes in the lens. The main cause of senile farsightedness is a violation of refraction. The patient sees a veil before his eyes, his vision is blurry. Other symptoms of cataracts are headache and fatigue.
Refractive error. The pathological phenomenon occurs with farsightedness, myopia, astigmatism. It is either congenital or acquired. Fog appears due to the fact that the image formation on the retina is disturbed. Other symptoms of pathology: migraine, weakness, increased eye fatigue. The state of health is normalized when the patient puts on glasses.
Macular degeneration. The macula is the spot located in the center of the retina. It forms an image that enters the structure of the brain. The clarity of the image depends on the condition of the macula. The organs of vision have substances that neutralize ultraviolet radiation. With age, these substances become less. If the macula is affected, all parts of the retina are affected. The patient cannot distinguish objects, as he sees a veil before his eyes.
Damage to the optic nerve. The organs of vision have nerve fibers that deliver the image to the cerebral cortex. If one of the fibers is affected, the myelin sheath is destroyed. The clinical picture depends on the stage of the pathological process. In severe cases, the disease can lead to blindness. If the nerve is partially affected, vision is preserved, but the patient sees a veil with. It is important to consult a doctor in a timely manner, thus, it will be possible to improve the prognosis of the pathology.
Brain tumor. When the cerebral cortex is damaged, a veil appears in front of the eye. Severe pathology is accompanied by migraine, visual impairment, hormonal failure. The clinical picture depends on the stage of the tumor.
Stroke and microstroke. A dangerous condition is associated with oxygen starvation of cells. The arteries located in the brain overlap, respectively, do not receive enough blood. At first, a veil appears before the eyes, then a headache appears, speech is disturbed, limbs are affected. A microstroke is less dangerous, since the vessel is blocked, but does not die. The patient becomes cloudy in the eyes, hearing disappears, coordination is disturbed. The maximum duration of symptoms is 5 hours. They pass on their own, however, the disease requires inpatient treatment.
Taking medication as a possible cause. Cloudy in the eyes of those who take glucocorticoids, antidepressants, drugs containing lithium. To avoid side effects, you need to follow the doctor's instructions, taking medications in the prescribed dosages. You cannot self-medicate.
Dry eye syndrome. The disease is not as harmless as it might seem. It is manifested by dryness of the cornea. Some patients are diagnosed with a deep pathological process, while others have a superficial one. Dry eye syndrome is associated with a lack of vitamin A. The disease can occur as a result of burns and injuries. It is accompanied by photophobia, a veil that occurs in the morning. Dry eye syndrome requires timely treatment. With this disease, the patient sees a white veil. At the initial stages, preparations analogous to artificial tears are effective. If the pathological process has covered the deep layers of the cornea, an operation is required.

Dark fog before my eyes

Diseases in which a dark veil appears.

Migraine. The disease occurs due to the fact that the brain does not receive enough blood. The main symptom of a migraine is discomfort in the head. Some people have a hereditary tendency to this pathology. A migraine occurs if the weather changes or a person sleeps too long. Other possible causes: overexertion, alcohol intake. Headache appears first, followed by a veil. In severe cases, dizziness occurs, speech is disturbed, hallucinations occur. The maximum duration of symptoms is 1 hour. The danger of a migraine is that it can lead to a stroke. If the disease manifests itself periodically, there is a possibility of a microstroke. The diagnosis is made by a neurologist.
Retinal disinsertion. The disease is associated with injuries in which the eyes suffer. In this case, the retina moves away from the shell that feeds it. Common causes: childbirth, trauma to the skull, falling from a height, regular eye strain. Predisposing pathologies: farsightedness, astigmatism, hypertension, diabetes mellitus. The retina does not completely peel off. The main symptom of the disease is flashes of light. Some patients see smooth lines, others see zigzag, dark lines. Retinal detachment is accompanied by pain in the eye. The veil increases in size. If the retinal lesion is extensive, the fog completely covers the organs of vision, double vision is possible. If the patient does not go to the doctor in time, the retina departs completely. At the initial stages, laser treatment is effective.

Red veil before the eyes

He points to a pathology in which blood flows into the vitreous body. Predisposing factors: hypertension, atherosclerotic lesions, diabetes mellitus, retinal dysfunction. Hemophthalmos is often associated with eye injuries. With such a disease, a red veil appears, fogging of the organs of vision occurs. If there is some blood in the vitreous, the patient sees flies. The disease affects the quality of vision. Hemophthalmos, which arose against the background of an injury, is accompanied by discomfort in the eye.

Other diseases

There are other factors that are not associated with ophthalmic diseases.

Vitreous body damage. The disease occurs as a result of an injury to the eye. The cause of destruction may be age-related changes. The vitreous body is affected if one or more vessels burst. Vision does not worsen, there is no headache.
Angiospasm of the retinal vein. Factors: atherosclerosis, toxic damage to the body. Pathology is manifested by hourly attacks. Flies or crooked lines appear before the eyes. With such a disease, brain cells receive little oxygen.
Osteochondrosis. Symptoms of pathology: pain in the neck, mainly in the back of the head, tinnitus. In some patients, a veil appears.
Multiple sclerosis. Pathology occurs when the myelin sheaths disappear. Multiple sclerosis is accompanied by optic neuritis.
