Why is vision lost? Causes of eye diseases

As a rule, in the initial stages of development, degenerative processes and many eye diseases do not manifest themselves in any way. But if your visual acuity decreases, then you need to see a doctor as soon as possible. After all, if the problem starts, then it may even be necessary surgery. The worst outcome is complete blindness. So, today you will learn why vision deteriorates - what to do, how to treat this or that disease.

Deterioration of vision in a child. Why is this happening?

Modern methods and equipment available to ophthalmologists make it possible to identify diseases of the visual organs, obtaining the most accurate information literally from the very birth of the baby. There are many causes of congenital pathologies, but the most common include birth injuries, heredity (the disease was passed on from parents), prematurity, and some anatomical features.

On a note! It should be remembered that congenital diseases are not diagnosed in a timely manner in all cases.

The appearance of the following signs should definitely alert you:

• rapid fatigue of the child;
• burning, ;
• headache;
• squinting, inability to look at distant objects.

Myopia is the most common ophthalmological problem in children today. According to statistics, it affects about 55% of children school age . Typically, the earlier the disease is diagnosed, the more difficult it is to treat. Myopia is especially common among those children whose parents have poor eyesight. And the most dangerous period, perhaps, is considered to be the time when the child goes to school - the strain on the eyes increases, moreover, the educational process is always fears and stress.

The problem only gets worse if:

• the child is interested in computers, TV, etc.
• his workplace is not organized correctly;
• the baby has incorrect posture;
• he leads a sedentary lifestyle;
• The child does not eat a balanced diet (there is a lack of vitamins).

To avoid the development of myopia, parents should strictly limit the time their child spends on the phone and computer. He should also be taught to hold his back and head correctly and play sports. Special attention deserves a diet - it should include sufficient quantity vitamins and useful elements, especially during the period of active growth of the child’s body.

Rules for working at the computer

How to plan work area child? It's simple - adhere to a few important requirements:

• the desktop should have a height corresponding to 1⁄2 of the baby’s height minus 5 cm;
• also the table should be located next to the window; Additional lighting is also required - on the right for a right-handed person and vice versa;
• your eyes should be from the book/notebook at a distance equal to the distance between your fingertips and your elbow.

Why does an adult's vision deteriorate?

There are many reasons for this problem, but the most common are the following:

• age-related changes;
• serious illnesses;

Important! The situation only gets worse if you have bad habits, frequent stress, poor nutrition, after bruises/injuries of the spine. In addition, diseases such as hypertension, osteochondrosis or diabetes are also accompanied by a decrease in visual acuity. And in order to identify them in time, you need to visit the office of a qualified ophthalmologist as early as possible.

Working at a computer for a long time can also cause your eyesight to deteriorate. See for yourself: under normal conditions, we blink approximately 18 times per minute, which is why the cornea becomes moist, but if we look at the screen for a long time, “dry eye” syndrome develops. Under such conditions, we blink less often than usual, which leads to drying out of the mucous membrane. The result is pain in the eyes, burning, redness, which can lead not only to, but also to inflammation of the corneal layer or even complete loss of vision!

Separately, it is worth mentioning farsightedness, a problem that almost all adults over 45 face. This is explained by hardening of the lens, decreased tissue elasticity, and dystrophy of the eye muscles. Increased fragility blood vessels, they become clogged with atherosclerotic plaques. Due to an imbalance in the inflow/outflow of fluid, the pressure inside the eyes increases, it begins to put pressure on the optic nerve, which as a result atrophies. As a result, glaucoma develops.

Symptoms of lens opacification are observed to varying degrees in 1/6 of all people over 40 years of age. If this process is started, it will ultimately lead to cataracts, so contact your ophthalmologist as soon as possible if you notice one of the following symptoms:

• photophobia;
• blurred vision;
• double vision;
• headache;
• « ».

Table. How to identify visual impairment - step-by-step instructions.

What to do if your vision deteriorates?

The answer is extremely simple - you need to use vision correction. Wearing glasses or contact lenses will allow you to feel comfortable and clearly see the surrounding objects. In addition, this will prevent the development of the disease. Indeed, as myopia progresses, for example, the eye shell stretches, and the retina can rupture or detach.

Vision correction using contact lenses

Lenses vary in length of wear. For example, one-day lenses from Bausch+Lomb Biotrue® ONEday are popular. They are made of HyperGel material, which is similar to the structures of the eye and tears, contains a large number of moisture - 78% and provides comfort even after 16 hours of continuous wear. This is the best option for dryness or discomfort from wearing other lenses. There is no need to care for these lenses; a new pair is worn every day.

There are also scheduled replacement lenses - silicone hydrogel Bausch + Lomb ULTRA, using MoistureSeal® technology (MoischeSil). They combine high content moisture, good oxygen permeability and softness. Thanks to this, the lenses are not felt when worn and do not damage the eyes. Such lenses require care using special solutions - for example, ReNu MultiPlus (Renu MultiPlus), which moisturizes and cleans soft lenses, destroying viruses, bacteria and fungi, is used to store lenses. For sensitive eyes, the optimal solution is ReNu MPS (Renu MPS) with a reduced concentration active ingredients. Despite the softness of the formula, the solution effectively removes deep and superficial stains. For long-term hydration of lenses, solutions with hyaluronic acid– a natural moisturizing component. For example, the universal solution Biotrue (Biotru), which, in addition to removing dirt, bacteria and fungi, provides 20-hour hydration of lenses due to the presence of hyaluronan polymer in the product.

Note! If a person squints and strains his eyes all the time, this creates additional stress, causing an even greater decrease in visual acuity. Visit a good ophthalmologist and let him choose the right glasses for you. Moreover, complex therapy they won't interfere at all.

Useful exercises

Most of therapeutic techniques includes gymnastics for the eyes. Good results eye muscle training is recognized by everyone. The set of exercises presented below is recommended to be repeated twice a day.

It is important that during execution the head remains motionless and the facial muscles are relaxed. To begin, take your starting position - that is, look straight ahead. These exercises should be repeated nine to ten times in each direction:

• raise your eyes up, then lower them down;
• move your eyes left and right;
• move your eyes clockwise on an imaginary dial, trying not to cut corners. Then drive counterclockwise;
• Raise your head and look up. Then repeat the exercises with the dial;
• perform all the exercises described above again, but after closing your eyes;
• describe the outline of an imaginary butterfly with your eyes;
• describe the figure eight.

Note! After completion, completely relax your eyes, blink slightly without straining.

What about folk remedies?

There are a number of folk methods that will be effective in case of deterioration of vision. First of all, this freshly squeezed carrot juice , mixed with parsley, celery and chicory juice in equal proportions. The resulting product must be taken every day.

In addition, it is very effective tincture, for the preparation of which take calamus and calendula in equal quantities, pour in 0.5 liters of vodka and leave for at least 12 days in a poorly lit place. Take 1 tbsp of tincture before each meal. spoon.

Note! Young nettles and blueberries (both in any form) also have a beneficial effect on vision. They also respond well to sprouted wheat sprouts.

Deserves special attention massage, effectively relieving fatigue and tension. It is quite possible to do it yourself, you just need to ensure that it is not accompanied by pain and discomfort.

As a result, we note that the problem of decreased visual acuity needs to be eliminated comprehensively, in mandatory after consulting your doctor first. Proper nutrition, exercise and minimizing stress - all this will have a positive effect not only on vision, but also on health in general!

Video - Causes and treatment of myopia

How much a person can do thanks to such a gift of nature as vision! It’s so wonderful to see nature and the change of seasons, interesting films and funny pictures! And how much you can read in books and newspapers. And it’s so nice to see a dear person, to watch his facial contours, smile, eyes. But, unfortunately, such joys are not available to everyone. After all, over time, some people’s vision begins to deteriorate. What should you do in such cases? Seek help from doctors and modern medical technologies, or the good old ethnoscience still not inferior modern analogues treatment?

This question is extremely difficult to answer - there are so many people, so many opinions. Everyone will have something to say on this issue. Someone forms their opinion based on subjective experience, based on stories and information read. And someone is familiar with treatment from their own experience and knows firsthand how this or that method, tested in practice, works.

Causes of decreased vision

There can be many reasons for loss of vision, and therefore everyone isolated case requires consideration. A common cause of deterioration is general disturbances in the functioning of the body, and loss of vision, as a rule, is just a consequence. Under general violations This can mean malaise, fatigue, various stresses, lack of nutrients in the body, and so on. If a person feels symptoms of vision deterioration, be it redness in the eyes, headache or heavy eyelids, then it is necessary to contact a specialist as soon as possible to diagnose the eyeball.

What to do?

In order to avoid unpleasant consequences, you need to reconsider your lifestyle and add many minor, but vital important habits. First you need to reduce the time you spend near the computer monitor or laptop. If this is not possible, and the work involves being at a computer, then we can advise you to sometimes take a break from the monitor and do warm-up exercises so that there are no precedents that cause your vision to drop sharply. What to do? Gymnastics. This will be discussed in more detail later. Screen time can also cause headaches. We should not forget about good nutrition and sleep. Because lack of substances and fatigue often lead to poor vision. What to do? It is better to consult about this not only with an ophthalmologist, but also with a therapist and nutritionist.

How to work with a computer correctly?

So how to work with a computer correctly so that your eyesight does not deteriorate? What should be done so that the user can perform his work normally without causing harm to the eyes? According to international standards It is generally accepted that you should spend no more than 6 hours a day behind a monitor screen. For children, this figure drops to four.

And you should always take breaks to rest. During rest, you can stretch your body by doing physical exercises and do eye exercises. Also, we should not forget about ergonomics. Proper arrangement of the workplace, although it will take a certain amount of time, but everyone will be able to work in comfort and safety. It is therefore necessary to use the monitor according to safety regulations, that is, at the correct angle and at the correct distance. An important factor affecting vision in the workplace is indoor lighting. Monitor brightness is also an important factor in the user's health.

Gymnastics for the eyes. What to do and how?

Gymnastics for the eyes is an excellent way to prevent vision loss. What to do for those who have just encountered a similar problem and have only heard about eye gymnastics, and even then only remotely? In fact, everything is very simple. Just a few minutes of warm-up will help relieve fatigue. To begin, close your eyes and warm them by placing your palms on your eyelids. You can also apply a few light pressures. Then it is recommended (with closed eyelids) to turn your eyes in different directions, now one way, then the other. A little squeezing your eyes won't hurt either. Some experts claim that tapping your fingers on the head from the back of the head to the frontal area also helps to relax the eye tissues. Then you need to open your eyes and move on to the second phase of warm-up gymnastics.

Here you can do a lot of different manipulations with vision, whatever you want - rotate your eyes in different directions, look at the tip of your nose, focus on objects at different distances, and so on. Experts also note the benefits of games with small balls, like table tennis. Such gymnastics should be performed regularly, approximately every hour.

If your eyesight decreases, what should you eat? Healthy foods

The text mentioned that vision impairment also occurs from a lack of nutrients in the body. And which ones should be used when vision declines? What to do so as not to feel a shortage of healthy products? You need to know, first of all, that the quality of vision directly depends on vitamins A and B6. Without them, a whole series of changes and ailments begin in the body, including vision problems, such as: increased sensitivity, to harsh light, “night” blindness, when a person sees absolutely nothing in the dark. Replenishing your supply of these substances is quite simple.

It is enough that the diet always contains foods such as carrots, cod liver, currants, cabbage, and citrus fruits. We should not forget about regular intake eating eggs, dairy products, various types croup If for some reason it is not possible to include all of the listed products in your diet, then you can take vitamins purchased at the pharmacy as food supplements. Also, some experts recommend periodically using moisturizing eye drops, such as Visine or Optiva.

Problems with blood vessels can also affect vision. Therefore, it is necessary to adhere to a strict diet that will help maintain healthy blood vessels. First of all, you should limit yourself to eating sweets and starchy foods and, if possible, completely avoid salt. Although some people who are accustomed to eating delicious food will find it difficult to refuse such delicacies, they should still look at the situation from the other side and realize that on the opposite side of the scale lies health, which is much more important. Moderate exercise is also recommended. And, of course, we should not forget about water balance in the body and take enough water. And most importantly, you need to make it a rule to regularly visit an ophthalmologist to check your vision.

At the age of 45, vision declines. How to proceed in this case?

According to statistics, vision loss most often occurs at the age of 45. What to do when your health is no longer the same as when you were twenty, but you still don’t want to get sick? At any age, the methods of treatment and prevention are the same. All the exercises and products described above will help when vision declines after 45 years. What to do if you still cannot do without glasses? It's simple - they should be worn with pride. Because everyone, and especially in such a time mature age, they give solidity and charisma. Or at least they can always be replaced with contact lenses.

Folk remedies. Are they effective?

Modern medicine has not yet fully mastered scientific point vision. More and more new treatment methods are emerging. And what can we say about the newest models? medical equipment, which you can’t master without special courses! But there is an alternative in situations where vision declines. What to do? Folk remedies are not yet outdated, but seem to be gaining more and more popularity. What is the secret of such techniques? Probably because they are time-tested, because people have been using them for centuries.

There are countless recipes for treatment with traditional remedies. And from every nation you can learn something original and useful. Firstly, traditional medicine implies proper nutrition, which has already been discussed in this article. Moreover, we are talking specifically about natural products grown without any chemicals and genetically modified organisms, on natural, clean land, preferably somewhere in the countryside. So if you have the opportunity to eat food from home gardens and vegetable gardens, then you should not neglect them. And then you can forget about the fact that your eyesight is deteriorating. What to do if it is already showing the first signs of this problem, but there is no opportunity or desire to use the services of an ophthalmologist for some personal reasons? This is where a lot of advice comes in handy.

Traditional methods: decoctions

Traditional medicine has provided many decoctions and compresses that can easily compete in effectiveness and with modern means. These are such as, for example, a decoction of calendula.

Nettle, for example, is a powerful tool against a whole range of ailments. By eating it with soups or simply steamed in boiling water, you can avoid many diseases.

Honey

If your vision is severely deteriorating, what should you do? quick effect? Consume honey. Honey compresses are very effective in treating the eyes, and if it causes a burning sensation, then you can simply eat a few spoons of it every day.

Useful plants and berries

Aloe and motherwort are not inferior in usefulness to any tablets or mixtures. They will be very effective in the struggle for a clear vision of the world around them. Let’s not forget about the recommendations for regular consumption of foods such as cabbage, parsley, and lingonberries. Especially beneficial properties has blueberries.

There are many known cases where vision was restored when daily diet this miracle berry turned on. And how many different compresses made from dandelions, mint, eyebright and other medicinal herbs have been preserved! Wheat grains are also useful - all this is a real storehouse of vitamins, which are so necessary for normal life.

A little conclusion

So, this is the 21st century, and the entire body, including our eyes, is under enormous stress, and as a result, vision decreases. What to do if this does happen? First of all, contact an ophthalmologist who will tell you competent treatment And effective gymnastics for eyes. But if you don’t trust doctors, you can always turn to old, proven methods.

A sharp deterioration in vision greatly changes the quality of life. The reasons for this may be different. When vision gradually declines, a person manages to adapt to the impairment. But the rapid loss of visual ability of the eye causes panic and can plunge one into severe depression. After all, more than 90% of the information received from the outside is provided by the eyes. To preserve vision, you need to pay attention to your eyes not sporadically (from time to time), but constantly. The visual function of the eyes also depends on the condition of the body as a whole. Why does a person begin to see poorly?

The first symptoms of the disorder visual function is considered the inability to qualitatively distinguish contours more or less distant objects, blurry pictures, “veil” before the eyes, inability to read, etc. Loss good quality vision problems are associated not only with defects in the visual organs themselves. A drop in visual acuity or its loss may be a symptom of serious systemic diseases body. The pathological condition of the eyes can be temporary (passing) or permanent, persistent.

Loss or deterioration of visual ability may be:

• bilateral - the lesion is most often the cause of a neurogenic disorder;
• unilateral - usually associated with a local problem (defect of eye tissue, local vascular pathology).

Why does vision decline rapidly, suddenly? The causes of a sharp, spontaneous loss of visual viability of the eyes (one or two) are usually classified as ophthalmological (directly related to the physiology and anatomy of the eyes) and general - those reasons that are associated with various general diseases of the body.

The loss of the main function of the eye is not always associated with organic disorders of the body.

Visual acuity may temporarily but sharply decrease due to fatigue, constant lack of sleep, prolonged stay in front of a computer monitor, especially if everyday life is associated with it work activity person.

Ophthalmic factors

A spontaneous decrease in the ability of one or both eyes to see well, its complete or partial loss is a consequence of many ophthalmological pathologies:

1. Injuries (mechanical, chemical) of the visual organs. We are talking about bruises of the eyeball, thermal burns, exposure to aggressive chemical substances into the eye, foreign objects, about orbital fractures. Particularly severe wounds are caused by piercing and cutting agents; loss of the ability to see in the eye is often a consequence of their exposure. Chemical agents often affect not only the superficial layer, but also the deeper structures of the eyeball.
2. Retinal hemorrhage. The reasons for this may be different - excessive physical activity, fragility of the vascular walls, prolonged labor activity, venous stasis, intraocular hypertension.
3. Acute eye infections (usually affecting not one, but both eyes) - fungal, viral, bacterial. This includes blenorrhea, conjunctivitis of various etiologies, keratitis, ulcers eye membranes. Loss of quality of vision is usually temporary.
4. Detachment of the retina and eyeball, their ruptures.
5. Optic neuropathy. The nature of the lesion is ischemic. A sudden drop in vision, usually one-sided, appears, but there is no pain. Examination reveals false edema optic nerve, pallor of the retina.
6. Retinal migraine is characterized by a monocular scotoma (a blind spot in the visual field). Its appearance is associated with dyscirculation in the central artery of the retina. It can alternate with another type of migraine - ophthalmological, in which attacks of severe headache are associated with visual dysfunction (sparks before the eyes, flickering, scotomas).

All these pathological conditions are acute. If your vision suddenly deteriorates, you should immediately consult a doctor. Timely assistance in most cases helps restore vision, stop its decline, and save the eyes.

Intracranial hypertension - benign

Promotion intracranial pressure benign nature is usually characteristic of girls who are prone to obesity and suffer from cycle disorders. Various pathologies predispose to the disease endocrine system, pregnancy, iron deficiency anemia.

Accompanied by severe pain in the back of the head, which can also be asymmetrical and generalized. Another characteristic symptom– severe visual dysfunction (reduced visibility). A special study indicates swelling of the optic nerve, congestion, hemorrhages.

Temporal arteritis

Inflammatory lesion arterial vessels: vessels of the head, eyes. This is accompanied by deterioration of vision. The causes of this pathology have not been definitively established. The disease quite often provokes complete one-sided blindness. The disease mainly affects older female representatives of the population.

In addition to eye symptoms, headache, tension and soreness of the temporal artery appear. Indicators are changing laboratory tests, which indicate the presence of an inflammatory process.

Amavrosis fugax

Amavrosis fugax – sudden blindness. Internal stenosis carotid artery observed in older patients. As a result of this pathology, a person’s vision suddenly and abruptly disappears. The reason is a transient fluctuation in the level of blood flow in the retina area. Other characteristic features: noise in the projection of the artery (determined during auscultation), contralateral hemisymptoms, weakness in the limbs, etc. Vision in one (usually) eye deteriorates completely unexpectedly, over a period of minutes or hours. The disturbance continues—loss of visual ability of the eye—for several hours.

Amavrosis fugax may be a consequence of retinal vascular embolism. The cause of the pathology is damage to the carotid artery (internal). With the blood flow, the embolic formation penetrates the vessels of the retina, causing ischemia. The body has a special function provided by nature - the dissolution of blood clots, therefore blindness is often transient. In the acute phase, the retinal artery is fused, and a thrombus is detected in it using additional research methods (angiography).

Other causative factors

Among the other reasons that cause vision loss are the following:

A person’s vision gradually decreases due to vascular damage due to diabetes mellitus ( diabetic retinopathy), the formation of cataracts and cataracts. Vision is impaired by pathologies of the visual organs such as farsightedness and myopia. The progression of these diseases leads to loss of the ability to see well. Natural wear and tear of eye tissue and the presence of many concomitant diseases are the reasons for decreased vision in old age.

Due to acute stress, visual dysfunction – “psychogenic blindness” – can occur. She threatens representatives more often fair half humanity.

Why? Women are distinguished by their emotionality and psychological sensitivity. The patient complains that her vision has sharply decreased. The reactions of the pupils of the eye are preserved, there are no pathological changes in the fundus.

Inattention to eye symptoms may result in complete loss of visual perception. Treatment depends on the cause of the disorder, severity pathological disorder. In any case, contacting a specialist is urgency. Take care of your eyes, monitor their health!

• Psychogenic reason.
• Bilateral ischemic infarction of the medulla in the area of ​​the vertebrobasilar system.
• Optical neuropathy of ischemic nature.
• Retrobulbar neuritis, which is a consequence of disseminated neuritis.
• Toxic optic neuropathy.
• Postangiographic (artificial).
• Sudden intracranial hypertension of benign and other nature.

If vision in one eye has sharply decreased (unilateral dysfunction), this may be due to:

• Trauma in the anterior cranial fossa or (fracture).
• Temporal arteritis.
• Optic neuropathy, which is a consequence of arteriosclerotic ischemia.
• An increase in intracranial pressure, which led to swelling of the nipple and.
• Retinal migraine.
• Amaurosis fugax, which is a consequence of stenosis of the internal carotid artery.

Bilateral vision loss

Ischemic optic neuropathy

In this condition, co-present ischemic lesion mesh shell. In some cases, bilateral ischemia occurs as a result of aortic arch syndrome if the patient suddenly changes his posture from bending forward to an upright position.

Bilateral infarction

If vascular blood flow is disrupted in the visual cortex, other signs of vertebrobasilar insufficiency are present. In this case, the onset of the disease is often sudden and is accompanied by impaired color vision. Typically, such changes are typical for elderly patients. Pupillary reactions in bilateral infarction are preserved, as a result of which it is necessary to distinguish it from visual agnosia.

Toxic optic neuropathy

The development of toxic symptoms occurs when consuming methyl alcohol. If vision has sharply deteriorated, this may be the result of prolonged tobacco abuse and ethyl alcohol. Sometimes visual impairment occurs due to poisoning with cyanide, isoniazid, trichlorethylene, antineoplastic agents, disulfuram, and methanol.

Retrobulbar neuritis

The first symptom multiple sclerosis in 16% of cases there is retrobulbar neuritis. In this case, an acute or less often subacute onset of the disease is noted. It is central vision that suffers the most. It must be remembered that retrobulbar neuritis is not always caused by multiple sclerosis. Sometimes it is a consequence of inflammation or infection, among which are tuberculosis, cryptococcosis, sarcoidosis, syphilis, toxoplasmosis, Lyme disease, brucellosis, mycoplasma. When viral encephalitis or viral infection occurs (mumps, measles, chickenpox, mononucleosis, rubella, herpes zoster, cytomegalovirus, hepatitis A), bilateral optic neuritis sometimes develops.

Benign intracranial hypertension

An increase in intracranial pressure of a benign nature is more typical for overweight girls who suffer from cycle disorders. With this disease, the development of symptoms is usually gradual. Among the main symptoms there is pain in the occipital region of the head, but sometimes the pain is asymmetrical or generalized. The second most common manifestation of benign hypertension is sharp deterioration vision. Fundus examination reveals papilledema. If you produce cerebrospinal fluid, the pressure is 250-400 mm aq. Art. CT signs intracranial hypertension is a decrease in the size of the ventricles of the brain. Much less often in this condition, damage to the abducens nerve occurs, which is unilateral or bilateral.

Usually the cause of hypertension cannot be determined, but sometimes this condition is preceded by various endocrine pathologies, iron deficiency anemia or pregnancy. If using conservative techniques cannot be restored normal level intracranial pressure, then trepanation is performed for the purpose of decompression.

Postangiographic blindness

With artificial vision loss (Anton's syndrome), toxic damage to the occipital lobes of the brain on both sides most often occurs. Visual function is restored, as a rule, after 1-2 days.

Intracranial hypertension

Increased intracranial pressure is often accompanied by attacks of amblyopia, the duration of which varies from several seconds to several minutes. When studying the visual fields, an increase in the size of the blind spot is noted, as well as peripheral narrowing. During ophthalmoscopy, serious congestion is detected in the fundus of the eye, and in some cases hemorrhages occur in the area. In the future, the loss of vision is more persistent.

Psychogenic blindness

Psychogenic vision loss occurs more often in women who are prone to such disorders. Most often, patients also have other signs of mental disorders (pseudoparesis, pseudoataxia, etc.). A distinctive feature is the preservation of normal pupillary reactions and an unchanged fundus. With other examination methods (EEG, evoked potentials, optokinetic), deviations are also not detected. This category of patients has a high degree of tolerance to sudden vision loss.

With bilateral damage to visual function, we are often talking about various neurological abnormalities.

Sharp unilateral visual impairment (amaurosis, amblyopia)

Fracture of the base of the skull

With a skull injury in the area of ​​the optic canal, anosmia may be present, external visible damage, the optic disc often becomes pale. Also available radiological signs bone defects.

Optic neuropathy

With arteriosclerotic optical neuropathy the nature of the lesion is ischemic. In this case, a unilateral decrease in vision suddenly occurs, but pain does not develop. In some cases, the presence of precursors in the form of temporary visual impairment is characteristic. During the examination, pseudoedema of the optic nerve (disc) and pallor of the retina are revealed. With this disease, total blindness never occurs. Among the most common causes of ischemia are diabetes, atherosclerosis, hypertension.

Temporal arteritis

Temporal arteritis affects arterial vessels, vessels of the head, vessels of the eyes, causing blurred vision. The reasons for its development are not fully understood. Inflammation of the temporal artery often leads to complete loss of vision on one side. This diagnosis is more often given to older women. In addition to decreased vision, headaches occur, and examination can reveal a tense temporal artery, which is painful on palpation. Also in the analyzes there is an increase in ESR. Arteritis is usually a systemic pathology.

Amaurosis fugax

As a result of stenosis of the internal carotid artery in elderly patients, vision temporarily decreases sharply, which is caused by a transient change in the level of blood flow in the area of ​​the retina. In addition, with this disease there is a noise on auscultation in the projection of the artery, contralateral hemisymptoms and other signs. In this case, unilateral visual impairment occurs suddenly (within minutes or hours). The duration of blindness also varies, rarely exceeding several hours. At the same time, there is weakness in the limbs that are opposite to the source of the disease. An ophthalmological examination can reveal signs of atherosclerosis of the vessels located in.

The direct cause of the development of amavrosis fugax is usually (90%) embolism in the vessels. The source of the embolus is most often the damaged wall of the internal carotid artery on the ipsilateral side. Then, with the blood flow, the formation enters the artery of the eye. Due to impaired blood flow, ischemic damage to the retina occurs, which results in decreased vision. Due to the fact that thrombotic masses often undergo spontaneous resorption, symptoms are transient.
IN acute stage disease, the retinal artery appears collapsed, and fluorescent imaging reveals a thrombus located in the lumen of the vessel. This study not performed often.

Interestingly, within a year after an attack of amavrosis fugax, a third of patients (30%) develop a disorder cerebral circulation. For a diagnostic search, Doppler ultrasonography is used, which allows you to confirm stenosis of the internal carotid artery.

Retrobulbar neuritis

This inflammation of the nerve tissue develops quite quickly. The peak of activity occurs, as a rule, in the first four days. Further pathological changes decrease and the patient's condition improves. In some cases, in addition to decreased vision, flickering in the eyes and pain in this area are associated. More often this state occurs in young patients and is unilateral, but bilateral lesions also occur. Retrobulbar neuritis never causes complete blindness. On early stages inflammation and changes in the fundus are absent, with the most significant loss of vision observed in the central region. In most patients, this condition may be the first sign of multiple sclerosis, which is subsequently diagnosed in 17-85%.

In addition to multiple sclerosis, retrobulbar neuritis can be a manifestation of the demyelinating disease syphilis.

Eye pathologies

Among the diseases of the eye itself, the cause of decreased vision can be: retinal detachment, inflammation, hemorrhage into the substance and retina due to tuberculosis, blood diseases, syphilis (Iles syndrome), which is accompanied by signs of retinal perivasculitis.

Retinal migraine

Retinal migraine is characterized by monocular migraine, the appearance of which is associated with discirculatory disorders in the central retinal artery system. This form The disease sometimes alternates with ophthalmic migraine, as well as with paroxysms of migraine without aura.

Ophthalmic migraine

With ophthalmic migraine, headache attacks occur, which are accompanied by homonymous visual dysfunctions (sparks, zigzags, flashes, scotomas). In this case, we are not talking about true loss of vision.

If a person suddenly has vision loss, what should he do? There is an explanation for this process that the patient may not even be aware of. In any case, you need to immediately conduct an examination and identify the cause. This is especially true if it is noticed that vision has fallen too sharply. What measures can be taken to stop this disease and is it possible to return to its former state of health?

Causes of the disease

The causes of visual impairment are very diverse. IN Lately everyone suffers from this problem large quantity of people. Some adults are diagnosed with nearsightedness or farsightedness, but these are not all possible deviations.

Vision deteriorates due to congenital pathologies in the body (received at birth), heredity, heavy eye strain, weak retina or constant stress. The process of vision loss in some cases can be explained by poor ecology in the place of residence. Incorrect reading in poor lighting and in transport also has a detrimental effect on the eyes.

Wrong habits, low-quality cosmetics, watching movies in 3D and piercing quickly spoil your eyesight. There are many points on the body that are responsible for one or another organ. If such an area is accidentally pierced, there is a high risk of decreased visual acuity, and sometimes this process leads to blindness.

In addition, a sudden problem occurs due to a number of diseases - diabetes, spinal pathologies, bruises and injuries, as well as viral diseases. Thus, vision begins to decline even during ordinary chickenpox. If a person eats poorly and sleeps little, this reduces his vital activity, which also causes decreased vision.

Spending a long time in front of a computer or TV can also affect this process. At the same time, the eyes become very strained if the lighting is too bright or dim. At the same time, the muscles of the lens become weak, since prolonged exposure to the computer at the same distance makes them weak and sluggish. For the same reason, the membrane of the eye dries out, because when a person blinks, hydration and cleansing occurs, and when looking at one point, blinking occurs several times less often. For a number of these reasons, vision decreases.

If vision has sharply deteriorated, this indicates a disease of the lens, retina or cornea of ​​the eye. In this state, a person does not distinguish clear contours of objects both at close and far distances. The patient has difficulty seeing the faces around him and feels foggy.
