A condition in which one eye sees worse than the other is called amblyopia. Dysfunction develops visual analyzer, i.e. violations of the relationship between the brain and the organs of vision.

Causes

Amblyopia is a pathology that can be eliminated. However, first of all, it is necessary to find out the reasons why it arose. These may include:

1. Temporal arteritis. It is accompanied by compression of the optic nerve by the artery, as a result of which the eye perceives worse visual information. This violation is dangerous because it can lead to complete loss of vision.
2. Stenosis of the carotid artery (typical for elderly patients). The basis of the pathology is a violation of blood circulation in the organ of vision.
3. Optic neuropathy (the underlying cause may be high pressure, diabetes, arteriosclerosis). At optic neuropathy pain does not occur. There may be harbingers of the disease, manifested by a temporary violation of visual function.
4. Retrobulbar neuritis. Inflammatory process which is characterized by rapid development. Accompanied severe pain and "flickering" in the eyes. It does not lead to complete loss of vision.

Provoking factors

Factors that increase the risk of developing amblyopia include:

• strabismus;
• heredity;
• circulatory disorders;
• nerve compression;
• injury to the organ of vision;
• traumatic brain injury;
• high blood pressure;
• born pathologies of the organs of vision;
• eye diseases of an infectious nature.

Types of amblyopia

1. Refractive. Occurs against the background of strabismus, myopia. It is a consequence of the systematic formation of a fuzzy image on the retina. It can develop as a result of not wearing corrective glasses.
2. Dysbinocular. Often develops against the background of strabismus.
3. Obscurative. The reason is genetic disorders. This form can be inherited.
4. Anisometropic. Pathology develops gradually, if one eye sees worse than the other by several diopters.

Treatment of amblyopia

You should contact a specialist when the first symptoms occur. The treatment of amblyopia is primarily focused on eliminating the cause that caused the disorder, enhancing the visual function of the weak eye and achieving good level vision in both eyes.

The specialist may prescribe the wearing of glasses or corrective contact lenses. Treatment can also be surgically. The operation is relevant in cases of strabismus or cataracts.

Recovery visual functions weak eyes use special visual exercises. They are most effective when used in early age. They also sometimes close one eye with good eyesight to activate the capabilities of the weaker. To do this, bandages are used and cover the healthy eye every day for several hours or for the whole day. Use this method for several weeks, months.

There are also special means that can be applied in such cases. For example, a doctor may prescribe wearing opaque contact lenses or instilling atropine drops into a healthy eye that will provoke a blurry image in it.

Other reasons why one eye sees worse than the other

Loss of vision in one eye may be due to:

1. conjunctivitis. This is one of the most common infections that occurs in both children and adults. The inflammatory process usually affects one eye, however, in the absence of hygiene and proper care may extend to the second. Characteristic features are swelling, lacrimation, pain in the eye, blurred vision. In the process of treatment, special drops are used, often from the category antibacterial drugs. Self-medication is prohibited, as it can lead to serious complications.
2. Herpes infection. The lesion is observed on the cornea of ​​the eye. Cases of the disease are more often recorded in the autumn-winter period. The onset of the disease is due to a decrease in immunity and a lack of vitamins. Treatment is aimed at suppressing the activity of the virus.
3. cataracts. The cause of the disease is retinal detachment. The inflammatory process leads to visual impairment and pain. Restoration of the impaired function in this case is possible only by surgical operation, during which the affected lens is replaced with a new one.
4. barley. Characteristic signs of its formation are compaction, hyperemia. A small abscess begins to form, which bursts after 5-7 days. It is advisable to consult a doctor at the first symptoms, since treatment started at an early stage can stop the development of inflammation.
5. Glaucoma. The development of glaucoma may be indicated by sudden pain in the eye, hyperemia of the eye, the appearance of a "veil". Nausea and vomiting may occur. The occurrence of such symptoms should be a reason to see a doctor.

The reason why vision is reduced in one eye may be hidden in cervical osteochondrosis. Pathology leads to compression of the aorta passing through spinal column and providing the optic nerve with full blood circulation.

To avoid worsening the condition, experts advise adhering to the following recommendations:

• perform exercises for the eyes;
• accept cold and hot shower(wash first with hot, then cold water);
• use artificial tears to moisturize the mucous membrane of the eyes;
• make compresses with parsley juice or black tea;
• use hypoallergenic and natural cosmetics;
• fulfill light massage eyes (pats, stroking, improving blood circulation).

How to protect your eyes from the effects of adverse factors

1. When performing any work, reading, writing, it is necessary to ensure that the lighting is sufficient.
2. The light should fall on what you are reading.
3. It is not recommended to read lying down or while riding in transport.
4. When working at a computer, it is necessary to monitor the distance from the eyes to the monitor - it should be at least 70 cm.
5. Be sure to remove cosmetics before going to bed, do not use it unnecessarily.
6. The eyes can be touched only with clean hands, so as not to provoke the penetration of infection.
7. Recommended preventive examinations ophthalmologist at least 2 times a year.
8. It is not recommended to look at the sun, bright light sources without protective equipment for eyes.
9. Do not lift heavy objects abruptly.
10. Any inflammatory infectious diseases in the body must be treated in a timely manner.
11. The time spent in front of the computer, TV should be dosed.
12. It is recommended to spend more time outdoors.

Diet to improve vision

Scientists name products, the regular use of which helps maintain eye health. These include foods containing vitamins A, B and C.

The diet should include:

• carrot;
• parsley;
• spinach;
• fish fat;
• currant;
• apricots;
• cottage cheese;
• pumpkin.

Sometimes comes amblyopia - a pathology in which one eye sees worse than the other. Translated from Greek word"amblyopia" means "lazy eye".

Amblyopia, fortunately, is reversible. It is based on a dysfunction of the visual analyzer, and not organic lesions eyes. Amblyopia is a condition where one eye cannot see properly due to a disruption in communication with the brain.

The main problem of patients suffering from lazy eye syndrome is the lack of binocular vision. Their brain simply refuses to synchronously read images from the right and left eyes. As a result, it is difficult for such patients to assess the surrounding reality - it loses its volume and habitual outlines.

The disease is most often caused by visual impairment in the early years of life (up to 7 years). The essence of the phenomenon is this: the images formed by the two eyes differ in quality, and human brain cannot combine them into a common visual picture. As a result, diplopia occurs - a split image.

In order not to get a split, the brain stops using the data of the eye that shows the wrong image on its retina. Therefore, it processes information received only from a healthy eye. Because all this is happening early childhood, the second eye ceases to develop normally and perform its functions.

risk zone

At risk are people suffering from strabismus or having relatives with strabismus. Also, amblyopia can overtake if not applied appropriate measures for the treatment of diseases such as myopia, hyperopia and clouding of the lens.

The most susceptible to the "lazy eye" syndrome are children with vision problems under the age of 7, as well as premature and weakened babies.

Types of amblyopia

Depending on the etiology, amblyopia is:

refractive - appears due to a systematic fuzzy image on the retina, due to the refusal to wear glasses with, hypermetropia, strabismus, etc .;

dysbinocular- occurs with strabismus;

obscurative - appears when congenital cataract and ptosis, which prevent the normal passage of light through the retina;

anisometropic- occurs if the difference in visual acuity of the right and left eyes is more than two diopters.

How to treat

Like any disease, amblyopia is best treated with initial stage. Therefore, the main component successful treatment - early diagnosis. It should be remembered that amblyopia does not go away on its own, and the sooner you resort to medical care the sooner the recovery will come.

The beginning of treatment will be an examination that will allow the identification of the root cause of the disease. And then, depending on the factors that provoked the disease, the ophthalmologist will prescribe adequate therapy: conservative or surgical.

Operative therapy is indicated for obscurative amblyopia, the purpose of which is to replace the lens, which cannot cope with the load and prevents clear vision.

conservative methods

Conservative treatment will begin with vision correction with glasses and lenses, and will continue with the use of special techniques:

• occlusion (“turning off” the eye, which sees better, with the help of dressings and films);
• penalization (artificial weakening of the sight of a more keen eye or);
• hardware optical-physiological therapy;
• pleoptic treatment (using computer programs).

Amblyopia can also be corrected by wearing special corrective glasses and hardware treatment, including the amblyocor apparatus and laser electrical stimulation. However, all procedures are permissible strictly for their intended purpose and under the supervision of a specialist.

Also speedy recovery activities such as solving puzzles, drawing and will help.

Where to treat

For help, you can contact an ophthalmologist at a regular clinic. He examines the condition of the eyes, necessary research, prescribe treatment, select glasses. Conservative treatment is also carried out in multidisciplinary clinics.

Private ophthalmological centers are also involved in the treatment of amblyopia, but all services are paid.

Price

Hardware methods of treatment in public clinics are free. If the cause is a cataract or, an operation is required to eliminate these disorders. The cost of strabismus correction starts from 20,000 rubles, cataract treatment - from 30,000 rubles.

Hello dear readers! We all know that the eyes are one of the most important organs, the health of which must be carefully monitored, protecting it from negative impact.

We are talking about regular visits to the ophthalmologist, carrying out therapeutic gymnastics, as well as compliance with the optimal mode of work and rest. Failure to comply with these requirements may result in serious problems.

To date, one of the worst eye diseases is astigmatism, in which one eye is nearsighted and the other is farsighted, which is not very good!

With age, significant changes in the visual apparatus occur, which lead to deterioration of vision and the risk of simultaneous occurrence of myopia and hypermetropia.

Because of complex structure human eye, there are many deviations, often intertwined with each other. To understand the causes that lead to the simultaneous occurrence of these diseases, it is first necessary to define them.

When the image is transmitted to the brain, light rays are refracted. When a person is healthy, light rays are refracted in the retina.

If the patient suffers from myopia (myopia), the eye is stretched and the rays are refracted outside the retina (in front). As a result, a person sees well with close range.

If the patient suffers from farsightedness (hypermetropia), the reverse situation emerges: due to the flattening of the eye, the light rays are focused behind the retina. In this state, a clear picture emerges at a long distance.

Often, as a result of such ailments, one or both eyes are affected by one pathology, but sometimes it happens that a person suffers from both hypermetropia and myopia at once.

The cause of such a complication may be another pathology - astigmatism (due to the unnatural shape of the cornea, the refractive power of the rays in some parts does not match). The focusing of the rays of light is carried out not at the 1st point, as in a healthy eye, but immediately at 2.

Why do pathologies develop?

Signs indicating the development of myopia and hypermetropia

Sometimes a person develops both hypermetropia and myopia overnight, or one eye is nearsighted and the other is farsighted. Why it happens?

Based on its results, the ophthalmologist will prescribe you special lenses, in which you will see the same with both eyes.

Be healthy! See you soon! Sincerely, Olga Morozova.

What is a disability? It is rather an established set of symptoms, diseases, and norms under which state benefits, as well as exemption from various works. Or labor activity in special conditions. Given the severity and capacity of a person, disability is divided into three groups. Let's consider each in the key of the state of the eyes, because very often it is by vision that a certain group is given.

First group

Let's start with the heaviest group. Bilateral narrowing of the boundaries of the field of view from ten degrees from the point of fixation.

The first group of vision is given in cases where a person does not see at 99% or at all. The reasons for this can be very diverse. Starting from congenital degradation of the lens or retina, ending with acquired, previous diseases and physical influences. Very often the problem arises due to careless handling of various objects or chemicals. For example, during welding, construction, work in chemical laboratories. That is why safety precautions are very important, without which an ambulance, partial or total loss vision is perfectly acceptable.

Sometimes blindness is not associated with local problems (specifically in the eyes), but in a general lesion of the central nervous system or certain centers of the brain responsible for visual perception. Or problems in the very connections of the brain with the eyes. For example, with cysts or tumors in the brain, it can put a lot of pressure on the centers responsible for vision. It begins to fall as the tumor grows. Sometimes it happens that the tumor is removed, but vision is no longer restored. In this case, there will also be a first disability group.

It also includes visual acuity of not more than 0.04 with correction for the best eye.

Second group

This group is a little "lighter". It can be given at certain diseases eye. For example, glaucoma or cataracts in complex forms may be indications for registration in a group.

In this case, visual acuity better eye- from 0.05 to 0.1, and the narrowing of the boundaries - from 10 to 20 degrees. Operation is possible only under certain conditions.

Third group

In this case, the main indicators will be visual acuity from 0.1 to 0.3 and narrowing of the boundaries of more than 20 degrees, but less than 40. The 3rd group also includes people who have one eye that does not see at all, and the other sees with a slight deviation . But at the same time, there are a number of additional conditions, including: loss of legal capacity, self-service opportunities or the need for rehabilitation, social protection.

From this it can be concluded that important question, if one eye does not see, while the second has 100%, as well as normal the physical state and the functioning of other body systems, a disability group is not allowed. In this case, the person is not considered incompetent.

Therefore, if in your case one eye does not see (by the way, this may also be the most different reasons), it is best to consult an ophthalmologist. Because only a specialist can give a qualitative assessment of the state, on the basis of which it is possible to obtain a group.

I must say that there are a number of vision problems in which a person does not fall under the group. Moreover, it is able to work in almost any conditions. Of course have certain types activities that will simply be impossible for him to do, or worsening of his condition is possible. In this case, a person will not be allowed to work after passing the commission. One simple example is high-altitude work. Due to changes in pressure, people suffering chronic diseases eyes are not always allowed to them. Therefore, in order to obtain a permit for industrial climbing and high-altitude work, it is necessary to pass a medical commission. AND Special attention given to vision.

It is also important when driving a car. With the 3rd group of disability, you can get the right, but at the same time a person must prove his full legal capacity in driving a car. Therefore, if you are registered, you must definitely tell about this when passing the medical examination. Because rights can be issued even to a person with a non-functioning one eye. But again, here you need to prove the full functionality of the other eye.

Sudden blindness (amaurosis) may be due to retinal detachment or ischemia and other eye diseases (for example, or uveitis), lesions optic nerves, bilateral damage to the visual cortex. Patients with acute visual impairment should be urgently hospitalized. At the same time, the information that the ambulance doctor manages to collect about the development of the disease has importance and helps to quickly establish a diagnosis at the hospital stage.

Causes of sudden blindness

Sudden blindness in one eye is usually the result of damage to the retina and other structures of the eye or optic nerve. One of its frequent causes is a transient circulatory disorder in the retina. Usually, patients complain of a veil that suddenly falls in front of the eye and sometimes captures only part of the field of vision. Sometimes there is a violation of sensitivity and transient weakness in opposite limbs.

The duration of the episode is from several minutes to several hours. In 90% of cases, the cause is retinal artery embolism from an ulcerated atherosclerotic plaque in the internal carotid artery, aortic arch, or from the heart (often with damage to the valves or). Less commonly, the cause is a drop in blood pressure in a patient with severe stenosis of the internal carotid artery. Sudden blindness in one eye is a harbinger and should be the reason for an active examination of the patient.

The chance of a stroke can be reduced by taking aspirin regularly (100-300 mg daily) or indirect anticoagulants(with cardiogenic embolism). In young people, retinal migraine may be the cause of transient blindness in one eye. The fall in vision in this case is a migraine aura that precedes or occurs shortly after the onset of the headache.

However, even with a typical history, it is advisable to exclude pathology with the help of a special study. carotid arteries and hearts. Differential Diagnosis also performed with visual aura in the form of a migrating flickering scotoma in a classic attack, but the visual aura usually involves the right and / or left visual fields in both eyes, and not one eye, in addition, it remains visible in the dark and when the eyes are closed.

Anterior ischemic optic neuropathy is caused by insufficient blood flow through the posterior ciliary artery that supplies the optic nerve head. Clinically, it manifests itself as a sudden loss of vision in one eye, not accompanied by pain in eyeball. The diagnosis can be easily confirmed by examining the fundus, which reveals edema and hemorrhages in the region of the optic nerve head. It most often develops in patients with long-term arterial hypertension and, often - in patients with vasculitis or.

In 5% of cases (especially often in patients older than 65 years), neuropathy is associated with temporal arteritis and requires immediate corticosteroid therapy to prevent damage to the second eye. The diagnosis of temporal arteritis is facilitated by identifying painful hardening and absence of temporal artery pulsation and signs of polymyalgia rheumatica. Posterior ischemic optic neuropathy is less common. It is usually caused by a combination of severe anemia and arterial hypotension and may be the cause of nerve infarction in the retrobulbar region.

Sometimes posterior ischemic neuropathy occurs against the background of massive blood loss during surgical interventions, gastrointestinal bleeding, injury. There are no changes in the fundus. At hypertensive crisis sudden loss of vision may be due to spasm of retinal arterioles or ischemic edema of the optic nerve head. unnecessarily rapid decline AD can lead to optic disc infarction.

Optic neuritis, an inflammatory demyelinating disease, often involves the retrobulbar part of the nerve (retrobulbar neuritis), so the pathology cannot be detected during the initial examination of the fundus. In most patients, in addition to an acute drop in vision, there is pain in the eyeball, which is aggravated by its movement. The disease often develops at a young age, can recur and is often the first manifestation of multiple sclerosis.

Intravenous administration large doses methylprednisolone (1 g per day for 3 days) accelerates recovery. Sudden blindness in both eyes may be a manifestation of toxic optic neuropathy. Toxic neuropathy may be associated with poisoning methyl alcohol, ethylene glycol (antifreeze) or carbon monoxide. More gradual development neuropathy of the optic nerves with increasing atrophy without a phase of disc edema can be caused by a number of medicines- chloramphenicol (levomycetin), amiodarone, streptomycin, isoniazid, penicillamine, digoxin, ciprofloxacin, as well as lead, arsenic or thallium poisoning.

Blindness can also be a consequence of the development of congestive optic discs (with benign intracranial hypertension or brain tumors). It is often preceded by short-term episodes of blurred vision in one or both eyes that occur with a change in body position and last several seconds or minutes.

In case of persistent vision loss, the administration of methylprednisolone (250-500 mg intravenously drip) and an urgent consultation with an ophthalmologist and neurosurgeon are necessary. Acute blindness in both eyes may also be due to bilateral infarction of the occipital lobes (cortical blindness) and result from blockage of the basilar artery (usually as a result of embolism) or prolonged systemic arterial hypotension. The source of embolism is usually atherosclerotic plaques in the vertebral arteries.

The development of blindness is often preceded by episodes of vertebrobasilar insufficiency with unilateral or bilateral paresthesia or paresis, ataxia, dysarthria, hemianopsia, dizziness, double vision. Unlike bilateral blindness caused by damage to the optic nerves, with cortical blindness, pupillary reactions remain intact.

Some patients with cortical blindness develop anosognosia: such a patient denies the presence of blindness, arguing that the room is dark or that he simply forgot his glasses. Acutely emerging blindness can be psychogenic in nature and be one of the manifestations of hysteria. Typically, such patients (more often young women) claim that everything around them is immersed in darkness (patients with organic cortical blindness often find it difficult to describe their visual sensations).

The anamnesis often reveals other hysterical symptoms (lump in the throat, pseudoparesis, hysterical seizures, mutism, hysterical gait disturbances). Pupillary reactions are normal, there are no stem symptoms. Unlike others, whose obligatory presence and extreme anxiety can serve as an additional diagnostic criterion, patients are often not alarmed, but rather calm, and sometimes even smile mysteriously ("beautiful indifference").
