Amblyopia— weakening of vision of a functional and often secondary nature (in the absence structural changes visual analyzer), which cannot be corrected with glasses or contact lenses. The frequency of amblyopia is about 2-2.5% in the general population.
Code by international classification diseases ICD-10:
ICD-10. H53. 0 Amblyopia due to anopsia. H54 Blindness and decreased vision
Amblyopia, translated from ancient Greek as “lazy eye,” is a condition in which coordinated work brain with eyes. Vision in one eyeball decreases, all brain work is directed to the functioning of the second eye.
There are primary and secondary forms of the disease. Primary is formed in the womb. Secondary acquired during life under the influence of unfavorable factors.
ICD-10 code: H53.0 Amblyopia due to anopsia
Violation binocular vision leads to an inability to appreciate the depth and volume of what you see. The assessment of the spatial arrangement of objects is impaired.
There are different degrees of manifestation of the disease; with a mild course of the disease, symptoms may not be expressed. Experts have identified individual symptoms in childhood and adulthood.
Amblyopia in children manifests itself in the following symptoms:
Symptoms in adults have a different character:
On entry level development, the patient is not aware of the existence of the disease and only accidentally notices different optical power eye.
Many factors can cause vision loss in one eye. People suffering from psychosis and hysteria, premature babies, and children with developmental delays are at risk.
Most often the disease occurs in childhood against the background of strabismus, when the work of one eye is disabled due to turning to the side.
The following ophthalmological diseases also become causes:
Diagnosis should be carried out by an ophthalmologist. Eye acuity is checked using special tables. In the presence of strabismus, it occurs determination of the angle of deviation from the norm by the Hirshberg method.
To identify amblyopia, you need to be examined by an ophthalmologist. After conducting tests for eye acuity, color correction, perimetry and refraction, the doctor will determine the severity of the disease.
At comprehensive study will be held additional examinations: Ultrasound of the eyeball, refractometry, skiascopy, consultation with a neurologist is scheduled.
There are five known degrees of amblyopia. The decline in eye acuity occurs progressively from weak degree to high.
Like any other disease, amblyopia is best treated at the initial level. The younger the patient, the greater the chance of achieving success in therapy. It is almost impossible to eliminate vision problems in adulthood.
For positive vision correction, it is necessary to determine the type of amblyopia and begin therapy by eliminating the causes.
Treatment methods, depending on the type, are divided into :
Treatment is aimed at achieving balanced visual acuity in both eyes of the patient.
The key to any recovery is not only the early detection of the disease, but also the impeccable implementation of all the ophthalmologist’s recommendations.
Important! The greatest effect of treatment occurs before the child reaches 6-7 years of age.
After this age, you can only count on partial restoration. In adults with amblyopia, the loss of vision is irreversible.
Poor treatment results are associated with ignoring recommendations for wearing glasses, the child’s reluctance or fear of visiting a doctor. As a result, time is missed when optic nerve It is not yet formed and can be easily corrected.
If the course of the disease is left to take its course, the outcome will be total blindness, especially in adulthood.
If treatment is interrupted, started late or not started at all, this will lead to a persistent decrease in the sharpness of the eyeballs. Failure to treat strabismus will lead to sensorimotor disorders. The most dangerous thing is loss of balance.
The high level of development of medicine today does not provide guarantees or protection. The only prevention for this unpleasant disease is an examination by an ophthalmologist. The child's first appointment is scheduled in the first month of life. You can then limit your visits to one per year.
At early detection clouding of the eyes, strabismus in the baby, it is necessary to timely eliminate these deficiencies.
From birth, babies must maintain a sleep-wake schedule. Children should be fed a balanced diet and health promotion activities should be carried out.
Amblyopia - functional impairment vision. With amblyopia, the contrast sensitivity of the eye and the ability to see objects clearly (the accommodative ability of one or both eyes) are impaired. Amblyopia cannot be corrected with glasses or contact lenses. The eyes see very different pictures from each other. And the brain is not able to combine them into one stereoscopic image, i.e. binocular vision is impaired. As a result, one eye begins to see worse.
Please note: The ability to combine two pictures into a single image is necessary for humans and other living organisms to estimate the distance to an object and the order in which objects are placed in the field of view.
Disease code according to ICD-10– H53.0 (all types of amblyopia). Amblyopia (“lazy eye”, this is how the name of the disease is translated from Greek), affects about 2% of the world's population. It is very important to identify amblyopia in a child or adult patient as quickly as possible, since the disease can progress over time. Amblyopia can lead to complications: the affected eye stops seeing.
Visual acuity in a patient with amblyopia can be restored at almost any age (both in children and adults), but the earlier treatment is started, the greater the chance of success and the lower the likelihood of developing disorders that are difficult to correct.
One of the most common causes of the disease is strabismus. Along with this, strabismus is a consequence of a violation of binocular perception (when both eyes see). This is possible if visual acuity in one eye is significantly reduced. In some cases, amblyopia develops if for a long time do not treat insufficient refraction of vision (impaired refraction of light in the eye, the image is not fixed on the retina and the eyes see worse).
Factors contributing to the development of amblyopia:
Amblyopia is promoted by family history. Amblyopia is more likely to develop if close relatives have the following diseases:
Diagnose the following types amblyopia:
The functional form of the pathology can be refractive, deprivation or anisometropic. This type of amblyopia occurs in children. younger age(up to 6-7 years old). Disbinocular amblyopia (appears with strabismus) also belongs to this group.
Hysterical amblyopia develops in children and adults with strong excitation and inhibition in the central nervous system.
Depending on how much visual acuity is reduced, there are 5 degrees of amblyopia:
Important:It is almost impossible to independently detect amblyopia.
The most typical symptoms amblyopia:
In the first 1-1.5 months after the birth of the baby, he must be taken to an appointment with an ophthalmologist or ophthalmologist. If a child belongs to the risk group for amblyopia, then until the age of 8 years he needs an annual scheduled examination. Visometry is used to diagnose amblyopia. At the same time, accommodation, the ability of the eyes to move simultaneously, as well as the degree of refraction are assessed (acuity in both eyes is taken into account).
If the doctor has diagnosed “lazy eye,” then it is necessary to use electrophysiological diagnostics to determine the causes of amblyopia.
Amblyopia therapy can be carried out in various directions. To restore binocular vision (vision in both eyes), strabismus is treated, visual acuity is corrected, and the amblyopic eye is trained using a set of exercises.
Currently, dysbinocular amblyopia and other types of this vision pathology are successfully treated using the Amblyocor device. The basis of the method is computer auto-training. The patient views the video, and the device’s sensors receive information about the functioning of the eyes, while simultaneously taking an encephalogram. The image automatically disappears if the visual clarity is reduced. The device stimulates neurons and forces the brain to restore image contrast.
Optical correction using contact lenses or glasses ensures the ability to see clearly at any time.
To combat this vision pathology, exercises have been developed that can be done at home.
Important:All exercises must be performed in dark room. A child's visual acuity improves if exercised every day for 3 months.

2359 08/02/2019 5 min.Amblyopia is a weakening of vision of a secondary nature. For all types visual pathology It is characteristic that in adulthood the deterioration in the quality of vision persists after removal of the main problem that caused amblyopia. The diagnosis of amblyopia in medical records may be indicated by a code. There is an International Classification of Diseases (ICD), according to which this or that disease is designated. Currently, the tenth classification is used - MBK-10. According to this classification, amblyopia due to anopsia (visual field defect) is designated by code H53.0
There are several types of functional disorder:
Amblyopia is caused by the non-participation of one of the eyes in the process of “seeing”, which is explained by an existing problem in the field of vision.
Since this functional vision disorder is secondary pathology, then the reasons for its occurrence can be called both the factors that caused functional disorders of the visual analyzer, and the processes that explain the decrease in vision. The likelihood of amblyopia increases due to the presence of a number of genetic characteristics. There are some types of inherited diseases that can cause amblyopia:
In cases where one of the parents suffers from amblyopia, the likelihood of its manifestation in the child is increased. Most often, this visual disorder manifests itself in families whose members suffer from strabismus and pronounced violations refraction. The immediate causes of the development of functional vision disorder are large number specific factors causing amblyopia. For example, in the case of amblyopia caused by strabismus, the pathology develops in the squinting eye. This is explained by the fact that the brain is forced to suppress the “picture” that comes to it from the squinting eye.
Manifestations of hysterical amblyopia are provoked by psychogenic factors that cause visual impairment, color perception, photophobia and other functional disorders.
The appearance of obscurational amblyopia is caused by opacification, dystrophy or injury of the cornea, cataracts, ptosis upper eyelid, serious. The cause of anisometropic amblyopia is high degree anisometropia. Deterioration of vision in this case manifests itself in the eye with more pronounced refractive errors (the process of refraction of light rays in optical system eyes). Amblyopia can develop if farsightedness, nearsightedness or astigmatism is not corrected for a long time.
A high risk of developing amblyopia occurs when children are born with severe prematurity or mental development delays.
Different forms of amblyopia also manifest themselves in different ways. Mild amblyopia may have no symptoms. In children, the possibility of developing amblyopia can be suspected if they have diseases that provoke such a visual disorder. The inability to small child fixate your gaze on a bright object.
Amblyopia may be indicated by deterioration in visual acuity that cannot be corrected. Also, manifestations of a functional disorder can be:
The hysterical form of amblyopia can occur under severe stress or emotional overstrain. This condition manifests itself as a sudden deterioration in vision, lasting from a few hours to several months. Deterioration in the quality of vision with amblyopia can vary. This is an almost imperceptible decrease in visual acuity and almost complete loss.
In order to diagnose amblyopia, it is important to conduct a comprehensive ophthalmological examination.
In the absence of treatment or untimely correction of visual disorders, visual acuity can significantly decrease. Over time, this process progresses steadily.
Treatment of this visual pathology can give the best results if it is carried out in early dates. Treatment methods are selected individually. All methods of “working” with a problem require consistency and persistence. Correction of this type of visual disorder is best done at an early age (children 6-7 years old); in patients 11-12 years old, amblyopia may not be correctable. It is important to conduct visual acuity testing for children before they enter school.
Treatment methods for amblyopia directly depend on the causes of vision impairment. However, most existing treatment methods consist of reducing or completely eliminating the “competition” of the dominant eye through direct occlusion (“closing” it) in various ways), which continues long time. At the same time, stimulation of the function of the amblyopic eye is carried out.
Treatment measures for refractive or anisometropic amblyopia involve the use of conservative methods. This is optimal vision correction, which is carried out using careful, or. It can also be carried out laser correction. Three weeks after the start of correction, the doctor prescribes pleoptic treatment (elimination of the predominant role of the better-seeing eye, as well as strengthening the functioning of the “weak” eye). Treatment of amblyopia includes physiotherapeutic procedures: vibration massage, reflexology, electrophoresis.
After the end of the pleoptia stage, the process of restoring binocular vision begins, which is achieved by orthoptic treatment.
In young children (1-4 years old), correction of the functioning of the visual organs is carried out using penalization, instilling an atropine solution into the “stronger” eye. This leads to a decrease in visual acuity of the dominant eye and activation of the amblyopic eye. In case of development of hysterical amblyopia in adults, may be prescribed sedatives, and psychotherapy sessions are also conducted.
When obstructive amblyopia manifests itself, resorption therapy is performed.
In the case of diagnosing obscurational amblyopia, surgery is performed. For dysbinocular amblyopia, strabismus correction is necessary, which is also performed surgically.
Most used folk remedies cannot improve vision with amblyopia. In most cases it is a waste of time and also real harm health.
Prevention of this visual disorder consists of measures that allow the pathology leading to the development of amblyopia to be detected as early as possible. This requires regular examination of children by ophthalmologists. It is important to conduct such examinations starting from the first month of life. If vision defects are identified, they must be corrected at an early age.
Amblyopia is called lazy eye syndrome. This visual disorder is secondary and is characterized by the non-participation of one of the eyes in the process of vision. Amblyopia is a disease that develops primarily in childhood. That is why its earliest detection and correction is important.
Treatment of amblyopia brings high-quality results only with responsible completion of a long course of treatment and compliance with absolutely all prescriptions of an ophthalmologist.

Brief description
Amblyopia- weakening of vision of a functional and often secondary nature (in the absence of structural changes in the visual analyzer), which cannot be corrected with glasses or contact lenses. The incidence of amblyopia is about 2–2.5% in the general population.
Code according to the international classification of diseases ICD-10:
- H53.0 Amblyopia due to anopsia
- H54 Blindness and decreased vision
Classification Anisometropic - develops when there is a significant difference in the refractive power of the media of the right and left eyes Deprivation (amblyopia ex anopsia) - a consequence of visual deprivation of one eye caused by congenital anomalies (for example, corneal opacity, cataracts) Dysbinocular - develops with strabismus: decreased visual acuity in the deviated eye due to location of the projection of the visual image is not in the center of the retina Hysterical (hysterical amaurosis, psychogenic blindness) - with hysteria, often in combination with other functional disorders of the visual analyzer (impaired color perception, narrowing of visual fields, photophobia, etc.) Obscuration - caused by congenital or early acquired clouding of the optical media of the eye; characterized by the preservation of reduced vision after the elimination of opacities. Refractive - with uncorrected refractive error, leading to unclear focusing of objects with one or both eyes.
Genetic aspects. If one parent has a history of amblyopia, the child is more likely to develop it. A number of inherited diseases are accompanied by amblyopia Benche's syndrome (*141350, В): asymmetric facial hyperplasia, strabismus 156190, В, reciprocal balanced translocation (8; 11) (q24.3; p15.1); mental retardation, short stature, amblyopia Kaufman syndrome Ophthalmoplegia with ptosis and miosis (*258400, r).
Risk factors. Amblyopia most often occurs in families with asymmetrical refractive errors, severe uncorrected refractive errors and strabismus.
Diagnostics An examination to identify refractive asymmetry, dysfunction of the abductor and adductor muscles of the eyeballs (amblyopia with strabismus), and determine the true visual acuity of each eye separately. A slit lamp examination and examination of the fundus are also necessary to exclude an organic cause of decreased visual acuity. The diagnosis of amblyopia is made only after exclusion all organic disorders that can reduce visual acuity All preschool children should undergo a full ophthalmological examination, and each eye should be examined separately. Children with amblyopia or strabismus in the family history are indicated for a special examination by an ophthalmologist.
TREATMENT
Lead tactics Correction of the disease underlying amblyopia must begin as early as possible. Amblyopia does not cure on its own, does not go away as the child grows up and always requires treatment. Complete correction of refractive errors of the affected eye and temporary switching off of vision in the second eye are necessary so that the amblyopic eye becomes the fixing eye. Observation of the patient from establishing a diagnosis of amblyopia until vision is completely restored.
Surgical treatment. Additional surgical correction of the position of the deviated eyeball, corneal transplantation, or cataract removal may be required.
Complications. If not treated in a timely manner, a significant permanent decrease in visual acuity is possible.
Course and prognosis Amblyopia in most cases is treatable, provided that the diagnosis is made in the early stages of the disease. Correction of refractive errors and surgical correction of the position of the eyeball can almost completely normalize vision. The development of the eyeball and visual analyzer occurs in childhood and adolescence, so treatment of amblyopia is most effective approximately up to 12 years of age.

Amblyopia is a functional vision disorder. With amblyopia, the contrast sensitivity of the eye and the ability to see objects clearly (the accommodative ability of one or both eyes) are impaired. Amblyopia cannot be corrected with glasses or contact lenses. The eyes see very different pictures from each other. And the brain is not able to combine them into a single stereoscopic image, i.e. binocular vision is impaired. As a result, one eye begins to see worse.
Please note: The ability to combine two pictures into a single image is necessary for humans and other living organisms to estimate the distance to an object and the order in which objects are placed in the field of view.
Disease code according to ICD-10– H53.0 (all types of amblyopia). Amblyopia (“lazy eye”, this is how the name of the disease is translated from Greek), affects about 2% of the world's population. It is very important to identify amblyopia in a child or adult patient as quickly as possible, since the disease can progress over time. Amblyopia can lead to complications: the affected eye stops seeing.
Visual acuity in a patient with amblyopia can be restored at almost any age (both in children and adults), but the earlier treatment is started, the greater the chance of success and the lower the likelihood of developing disorders that are difficult to correct.
Causes of amblyopia
One of the most common causes of the disease is strabismus. Along with this, strabismus is a consequence of a violation of binocular perception (when both eyes see). This is possible if visual acuity in one eye is significantly reduced. In some cases, amblyopia develops if insufficient refraction of vision is not treated for a long time (impaired refraction of light in the eye, the image is not fixed on the retina and the eyes see worse).
Factors contributing to the development of amblyopia:
- severe ametropia (nearsightedness or farsightedness);
- prematurity;
- low weight of the newborn baby;
- retinopathy (pathology of the retina) due to prematurity;
- congenital cataract;
- mental retardation in a child;
- Cerebral palsy (cerebral palsy).
Amblyopia is promoted by family history. Amblyopia is more likely to develop if close relatives have the following diseases:
- strabismus;
- isoametropia;
- anisometropia.
Classification of types of amblyopia
The following types of amblyopia are diagnosed:
- functional;
- organic;
- hysterical amblyopia (“psychogenic blindness”).
The functional form of the pathology can be refractive, deprivation or anisometropic. This type of amblyopia occurs in young children (up to 6-7 years). Disbinocular amblyopia (appears with strabismus) also belongs to this group.
Hysterical amblyopia develops in children and adults with strong excitation and inhibition in the central nervous system.
Depending on how much visual acuity is reduced, there are 5 degrees of amblyopia:
- 1st degree – visual acuity - 0.8-0.9 diopters;
- 2nd degree – 0.5-07;
- 3rd degree – 0.3-04;
- 4th degree – 0.05-0.2;
- 5th degree – visual acuity – 0.05 diopters and below.
Important: It is almost impossible to independently detect amblyopia.
The most typical symptoms of amblyopia:
- problems with the perception of three-dimensional objects;
- inability to determine the approximate distance to an object;
- decreased visual acuity (in one eye or both eyes);
- diplopia (objects appear double) when viewed with both eyes;
- deviation of one eye from the direction of gaze.
In the first 1-1.5 months after the birth of the baby, he must be taken to an appointment with an ophthalmologist or ophthalmologist. If a child belongs to the risk group for amblyopia, then until the age of 8 years he needs an annual scheduled examination. Visometry is used to diagnose amblyopia. At the same time, accommodation, the ability of the eyes to move simultaneously, as well as the degree of refraction are assessed (acuity in both eyes is taken into account).
If the doctor has diagnosed “lazy eye,” then it is necessary to use electrophysiological diagnostics to determine the causes of amblyopia.
Treatment of amblyopia
Amblyopia therapy can be carried out in various directions. To restore binocular vision (vision in both eyes), strabismus is treated, visual acuity is corrected, and the amblyopic eye is trained using a set of exercises.
Currently, dysbinocular amblyopia and other types of this vision pathology are successfully treated using the Amblyocor device. The basis of the method is computer auto-training. The patient views the video, and the device’s sensors receive information about the functioning of the eyes, while simultaneously taking an encephalogram. The image automatically disappears if the visual clarity is reduced. The device stimulates neurons and forces the brain to restore image contrast.
Optical correction using contact lenses or glasses ensures the ability to see clearly at any time.
To combat this vision pathology, exercises have been developed that can be done at home.
- The child covers his healthy eye with his palm and brings a piece of paper with text to the weakened one. You need to bring the sheet closer to your face until the letters begin to blur. Then the paper is moved away until the text becomes legible again.
- Take a light bulb of medium power (optimally 60-70 W) and attach a black circle of paper (diameter 6-8 mm) to it. The child looks with the amblyopathic eye at the glowing lamp for 30 seconds, after which he turns his gaze to a blank sheet. You need to look at the white surface until the “imprint” of the black circle on the light bulb appears on it.
- Take a powerful 100-watt light bulb and cover it with a light-proof cap with a hole cut in it (diameter - 5 mm). The hole is covered with a translucent red film. The child looks at the glowing red circle for 3 minutes with a weakened eye from a distance of 40 cm. Parents should alternately turn the lighting device on and off every 2-3 seconds.
Important: All exercises must be performed in a dark room. A child's visual acuity improves if exercised every day for 3 months.

Amblyopia, translated from ancient Greek as “lazy eye,” is a condition in which the coordinated work of the brain and the eyes is disrupted. Vision in one eyeball decreases, all brain work is directed to the functioning of the second eye.
There are primary and secondary forms of the disease. The primary one is formed in the womb. Secondary is acquired during life under the influence of unfavorable factors.
ICD-10 code: H53.0 Amblyopia due to anopsia
Impaired binocular vision results in the inability to judge the depth and volume of what you see. The assessment of the spatial arrangement of objects is impaired.
There are different degrees of manifestation of the disease; with a mild course of the disease, symptoms may not be expressed. Experts have identified individual symptoms in childhood and adulthood.
Amblyopia in children manifests itself in the following symptoms:
- Strabismus.
- Tilt of the head when reading, or closing one eye.
- Poor coordination of movements.
Symptoms in adults are different:
- Double vision.
- Veil, vagueness.
- Sudden deterioration in vision for a long period or a couple of hours.
At the initial level of development, the patient is not aware of the existence of the disease and only accidentally notices the different optical powers of the eyes.
Many factors can cause vision loss in one eye. People suffering from psychosis and hysteria, premature babies, and children with developmental delays are at risk.
Most often, the disease occurs in childhood against the background of strabismus, when the work of one eye is disabled due to turning to the side.
The following ophthalmological diseases also become causes:
- Anisotropy.
- Cataract.
- Long-term clouding of the crystal.
- Drooping eyelid.
Diagnosis should be carried out by an ophthalmologist. Eye acuity is checked using special tables. In the presence of strabismus, the angle of deviation from the norm is determined by the Hirshberg method.
To identify amblyopia, you need to be examined by an ophthalmologist. After conducting tests for eye acuity, color correction, perimetry and refraction, the doctor will determine the severity of the disease.
During a comprehensive study, additional examinations will be carried out: ultrasound of the eyeball, refractometry, skiascopy, and a consultation with a neurologist will be scheduled.
There are five known degrees of amblyopia. The decline in eye acuity occurs progressively from low to high.
Like any other disease, amblyopia is best treated at the initial level. The younger the patient, the greater the chance of achieving success in therapy. It is almost impossible to eliminate vision problems in adulthood.
For positive vision correction, it is necessary to determine the type of amblyopia and begin therapy by eliminating the causes.
Treatment methods, depending on the type, are divided into:
- Traditional. Occlusion - turning off the healthy eye using occluders.
- Surgical intervention. Obscurational amblyopia requires correction of ptosis, removal of cataracts and correction of strabismus surgically.
- Conservative. For refractive disease, conservative methods of therapy are used. Glasses are selected and laser correction is performed.
- Physiotherapeutic. Medicinal electrophoresis, vibration massage and reflexology give good results when stimulating the sore eye.
- Psychotherapeutic. If a patient has hysterics associated with a disease, sedatives are prescribed.
Treatment is aimed at achieving balanced visual acuity in both eyes of the patient.
The key to any recovery is not only the early detection of the disease, but also the impeccable implementation of all the ophthalmologist’s recommendations.
Important! The greatest effect of treatment occurs before the child reaches 6-7 years of age.
After this age, you can only count on partial recovery. In adults with amblyopia, the loss of vision is irreversible.
Poor treatment results are associated with ignoring recommendations for wearing glasses, the child’s reluctance or fear of visiting a doctor. As a result, time is missed when the optic nerve is not yet formed and can be easily corrected.
If the disease is left to run its course, the outcome will be complete blindness, especially in adulthood.
If treatment is interrupted, started late or not started at all, this will lead to a persistent decrease in the sharpness of the eyeballs. Failure to treat strabismus will lead to sensorimotor disorders. The most dangerous thing is loss of balance.
The high level of development of medicine today does not provide guarantees or protection. The only prevention of this unpleasant disease is an examination by an ophthalmologist. The child's first appointment is scheduled in the first month of life. You can then limit your visits to one per year.
If clouding of the eye or strabismus in a child is detected early, it is necessary to promptly eliminate these deficiencies.
From birth, babies must maintain a sleep-wake schedule. Children should be fed a balanced diet and health promotion activities should be carried out.Amblyopia - rare disease, related to eye diseases that reduce visual acuity. Worldwide, no more than 2% of people on the planet suffer from this disease. This disease most often affects children, so timely consultation with a doctor and the appointment of competent therapy will help restore good eyesight and live without glasses.
