What is night blindness. Classification and characteristics of types of night blindness. Which doctor treats

Article content: classList.toggle()">expand

Night blindness in humans is an eye pathology in which there is a decrease in visual acuity in poor lighting conditions (at dusk, in low artificial light, etc.). In addition, this condition is characterized by a narrowing of the visual fields and impaired perception of colors. In the medical literature, night blindness is called hemeralopia.

The mechanism of formation of hemeralopia

The retina of a healthy person consists of two types of cells - rods and cones. The rods provide black and white vision, and the cones provide color vision. The normal ratio of cones to rods is 18:1.

Rod cells are made up of a special visual pigment called rhodopsin.. Under the action of light, it disintegrates, and in the dark it is restored. During the restoration of rhodopsin, energy is released, which is converted into impulses and transmitted to the frontal lobes of the brain. Due to this reaction, the so-called twilight vision is provided. For the full restoration of rhodopsin, a sufficient amount of vitamin A is necessary.

With a lack of vitamin A or a violation of the ratio of rods and cones, night blindness develops.

Why is the disease called night blindness?

The fact is that the chicken retina is designed in such a way that it contains only cones. Thus, birds have good eyesight and distinguish colors. However, this is only possible in good lighting conditions. Chickens can hardly see in the dark.

Classification and causes

There are three types of night blindness:

In ophthalmology, there is such a thing as false night blindness.. It is characterized by a slight deterioration in vision in the dark and is caused by banal overwork of the eyes. False hemeralopia does not need medical treatment and goes away on its own after a good rest.

The following factors can provoke night blindness:

Menopause;
Malnutrition (especially vegetarianism);
Infectious diseases (rubella, chicken pox, herpes infection, measles).

Night blindness symptoms

First of all, the symptoms of night blindness in humans are manifested by a decrease in vision in poor lighting. There may be discomfort associated with a feeling of dryness or a foreign body in the eye. At the same time, orientation in space is disturbed, especially with a sharp transition from a bright room to a dark one.

Evening vision of a healthy person and a person with night blindness:

Night blindness is accompanied by a narrowing of the visual fields and a violation of light perception. Most often, people have difficulty differentiating between blue and yellow.

Older people may develop Iskersky-Bito plaques. They are spots on the conjunctiva of the eyelids (back surface of the eyelids), which are gray in color and do not rise above the surface of the mucous membrane.

Let's look at the lack of which vitamin causes night blindness in humans:

Hemeralopia caused by a lack of vitamin A - then in addition it is accompanied by dry skin, bleeding gums, the appearance of hyperkeratosis (areas of rough skin compaction). These symptoms are often accompanied by itching and scratching of the skin. If there is beriberi (complete lack of vitamin A), then a person develops keratomalacia - softening of the cornea of the eye, in place of which erosion and ulcerative defects occur in the future.

Children suffering from night blindness are very often afraid of the dark and behave very restlessly when evening comes.

Diagnostics

To make a diagnosis of "Hemeralopia", an ophthalmologist must conduct a series of examinations:

In some cases, the doctor can conduct a more detailed diagnosis using refractometry, electroretinography, as well as ultrasound scanning of the eyes.

Night blindness treatment

If night blindness is congenital, then, unfortunately, it is practically not amenable to correction.

For the treatment of acquired forms of night blindness, it is important to establish the root cause of the disease.. If it is associated with myopia or farsightedness, it is necessary to choose the right glasses or.

In some cases, surgical intervention is required (laser keratomileusis, scleroplasty, removal and replacement of the lens, keratoplasty). The choice of a particular type of intervention depends on individual indications.

Essential hemeralopia can be eliminated by normalizing the diet.

As for essential hemeralopia, night blindness caused by a lack of vitamin A, it can be eliminated by normalizing the diet.

The following foods are rich in vitamin A: cod liver, fresh carrots, spinach, butter, tomatoes, fatty cheese, dairy products, eggs, fresh herbs, blueberries, mountain ash, apricots, black currants, blackberries.

Ophthalmologists often prescribe vitamin preparations: nicotinic acid, riboflavin, vitamin A. The dosage is selected individually, depending on the severity of hemeralopia and the general condition of the patient.

Forecast and prevention

As already mentioned, congenital night blindness is practically untreatable. A more favorable prognosis for essential and symptomatic hemeralopia. However, they can also lead to vision loss. To judge an accurate prognosis, the doctor must carefully examine the patient and assess all risks.

Many people with night blindness develop a persistent fear of the dark.. This is especially true for children. Sometimes this is in the nature of a phobia, and sometimes it can develop into obsessive mental disorders.

Prevention of night blindness includes the following activities:

Eye diseases and diseases associated with vision can befall a person at any time throughout life from birth. Some ailments are acquired in certain conditions, others are inherited. And in all situations, it is necessary to be aware of the possibilities of treatment, prevention and the consequences of inaction, especially when it comes to such common deviations as night blindness.

Disease Definition

In a medical way

As prescribed by the doctor, patients are required to take vitamins A and PP, as well as elements of group B. The dosage, as a rule, is set by the doctor. In some cases, it is possible to prescribe riboflavin - eye vitamin drops twice a day, one drop in each eye. Self-medication in the prevention and treatment of deviations is not recommended.

Folk remedies

In the treatment of any diseases (including eye diseases), folk methods do not lose their popularity. However, before using them, it is necessary to consult with doctors, especially if they act as an addition to the main ones, since the perfect compatibility of various drugs and preparations is also important.

In addition to enriching the diet with fortified foods, you can drink one grain of mustard per day, gradually increasing the dosage to twenty pieces. It will also be useful to take fish oil according to the instructions proposed by the manufacturer of the drug.

Comprehensive treatment can be supplemented by the regular use of infusions and decoctions of herbs:

From cornflower. 10 grams of grass should be poured with a glass of hot water for 15 minutes and taken in a tablespoon three to four times a day before meals.
Medicinal collection. In equal proportions (one teaspoon each), lingonberry, viburnum, primrose, blackberry, lemon balm, raspberry and green mountaineer root are mixed and insisted in a third of a liter of boiling water for 1 hour. Take half a glass three times a day.

Prevention

If visual impairment in the dark is not caused by congenital pathologies, prevention can be carried out. First of all, you need to monitor your diet and, if possible, check the level of vitamins in the body. It is recommended to wear high-quality sunglasses and avoid frequent use of solarium services. It is important to systematically visit an ophthalmologist, especially if there is a risk of hemeralopia. If a person has cataracts, glaucoma and other diseases of the organs of vision, it is necessary to start their treatment on time in order to prevent the development of complications in the form of night blindness.

To reduce the risks of any eye diseases and vision disorders, it is necessary to limit the use of electronic gadgets and not spend much time in front of a computer screen, especially in the evening.

With hereditary night blindness, systematic observation by an ophthalmologist from birth is necessary. Prevention in this case is impossible, but the symptoms of the disease can be alleviated if all the recommendations of medical professionals are followed.

conclusions

Hemeralopia or night blindness is a disorder in the quality of vision that can cause a lot of trouble for the patient, up to mental disorders. But with the right appointment and treatment, any discomfort associated with this deviation can be reduced, even if it is congenital. And prevention and care for one's own health can save a person from the likelihood of acquiring an ailment.

Night blindness, or hemeralopia (from the Greek. hemera - day, alaos - blind, blinding and ops - eye), is a sharp deterioration in vision in low light conditions (at dusk, at night, when moving from a brightly lit room to a dark one, with artificial dimming). There is a corresponding deterioration in spatial orientation, there may also be a narrowing of the visual fields and a decrease in the perception of blue and yellow colors.

Why can't you see in the dark?

Rod photoreceptors in the retina are responsible for vision in low light. As you know, under the action of light, the visual pigment of the rods - rhodopsin - disintegrates. Its regeneration occurs with the participation of vitamin A, and this takes a certain time. Thus, at the heart of night blindness are either structural changes in the rods or a deficiency of rhodopsin.

What is night blindness?

There are congenital, symptomatic and essential hemeralopia.

congenital hemeralopia It is hereditary and manifests itself in childhood or adolescence. With congenital hemeralopia, there is a persistent decrease in vision at dusk, a pronounced decrease in adaptation to the dark.

Symptomatic hemeralopia observed in some types of retinal dystrophy (for example, tapetoretinal dystrophy), with chorioretinitis (inflammatory diseases of the retina and choroid), optic nerve atrophy, glaucoma, complicated myopia, siderosis and other eye diseases. In addition to night blindness, in these cases there are other clinical manifestations corresponding to a specific disease.

Essential hemeralopia due to insufficient intake of vitamin A (retinol) or a violation of its metabolism. The cause may be a violation of general nutrition during fasting, alcoholism, liver disease, malaria, neurasthenia, etc. In most cases, essential hemeralopia is temporary.

Other manifestations of the disease

Essential hemeralopia is characterized by the appearance on the conjunctiva of the eyeball of xerotic Iskersky-Bito plaques - dry flat spots, usually located within the palpebral fissure. With more severe vitamin A deficiency, there may be necrosis (death) and melting of the corneal tissue (keratomalacia). With general beriberi, there are characteristic signs of vitamin deficiency: weight loss, dry skin, bleeding gums, etc.

When examining visual fields, their narrowing is noted, especially in yellow and blue colors.

Fundus: in congenital and symptomatic hemeralopia, changes in the fundus are determined by the underlying disease; in essential hemeralopia, the fundus is not changed.

Treatment, prevention, prognosis

Congenital hemeralopia is currently not treatable.

With symptomatic hemeralopia, the underlying disease is treated.

The treatment of essential night blindness is based on an increase in the intake of vitamin A into the patient's body, including in the form of drugs. At the same time, the intake of vitamins B2, PP is also prescribed. A diet rich in vitamin A is shown: milk, butter, liver, carrots, lettuce, spinach, green onions.

Prevention of primary (essential) hemeralopia is a sufficient intake of vitamin A with food.

The prognosis is favorable in the treatment of essential night blindness. With symptomatic hemeralopia, the prognosis depends on the nature and severity of the underlying disease.

Night blindness is a popular designation for the pathology of vision, which in medicine is called hemeralopia or nyctalopia. The ailment manifests itself in a significant deterioration in visual perception in low ambient light. At the same time, a person's coordination is disturbed, the fields of vision are narrowed, and an incorrect perception of things in blue and yellow shades is noted.

Etiology

Night blindness has specific causes of manifestation. Doctors have identified that the disease may have a congenital etiology, the causes of which have not been precisely determined. The main provoking factor is associated with a lack of vitamin A in the body.

Nyctalopia, another medical term for night blindness, also acts as a symptom of various pathologies that are based on damage to the retina:

high degree;
pigmented;
siderosis.

With a lack of vitamins A, PP, B2, visual perception also deteriorates in humans. Certain ailments and indicators can provoke this condition:

unbalanced diet;
starvation;
or ;
liver disease;
damage to the gastrointestinal tract;
alcoholism;
depletion of the body;
certain medicines;
prolonged exposure to bright light.

Classification

Based on the etiology of the disease, clinicians determined that night blindness, as a disease, can manifest itself in three forms:

congenital - develops according to a hereditary factor in childhood;
essential - night blindness is formed from a lack of vitamins and trace elements, with a violation of the structure of the retina;
symptomatic - progresses from concomitant ailments that affect the retina or optic nerve.

Also in medicine, another type of disease is distinguished, which is called false hemeralopia. It manifests itself in an insignificant violation of visual function in the dark. The disease is provoked by severe overwork of the eyes. This type of disease does not require medical assistance, which makes it enough for the patient to fully rest.

Symptoms

As a rule, night blindness occurs in people from vitamin deficiency. Therefore, it will not be difficult for the patient to cope with such an ailment. In order to recognize the disease in time, a person needs to monitor all changes in vision, especially during twilight.

Doctors identified the main symptoms in a person with night blindness:

gradual deterioration of visual perception;
the retina reacts poorly to a light source;
color perception deteriorates;
dark spots appear;
sensation of a foreign body;
loss of orientation in space.

If night blindness manifested itself in an adult, then Iskersky-Bito plaques may indicate the disease. They appear as spots on the conjunctiva of the eyes and are colored in a characteristic gray color, and are also flush with the surface of the shell.

In case nyctalopia has developed due to a lack of vitamins, then the patient has slightly different symptoms. A person shows some of the above-mentioned changes, as well as the skin is dehydrated, the gums begin to bleed, and strongly compacted areas appear on the body. Night blindness is manifested in characteristic signs, to which such symptoms are added - and keratomalacia. In a place where the cornea of \u200b\u200bthe eye has softened a little, the patient may experience erosion or an ulcer.

In childhood, anxiety is manifested with the onset of the dark time of the day.

Diagnostics

A disease such as night blindness can only be established by a doctor. If a person has any of the above symptoms, then you should definitely contact an ophthalmologist. With the help of electroretinography and analysis of the anamnesis, the physician can establish the correct diagnosis and determine the causes of the eye anomaly.

Also, in diagnostic measures, the patient can be sent for such examinations:

perimetry - identification of the fields of the eye;
adaptometry - a test for the perception of a light source;
electrooculography - examination of the eye muscles and the surface of the retina during eye movement.

Treatment

If a person is diagnosed with congenital hemeralopia, then its treatment is impossible. Other forms of the disease can be cured with medication and folk methods. In very rare and severe cases, doctors resort to surgical therapy.

The problems with the eyes of the essential type can be eliminated with the help of a diet. The patient is simply prescribed the use of more vitamin A, as well as the observance of a correct and healthy daily routine. Diet therapy, which can be prescribed to the patient, is based on the use of such ingredients:

carrot;
egg yolk;
tomatoes;
cheese dairy product;
millet;
berries;
butter;
spinach;
beef liver.

Also, the patient should not forget about fresh vegetables and fruits. Doctors recommend eating more peaches, pumpkins, green peas, parsley and apricots. In addition to vitamin A, the body needs to be enriched with vitamin E. To do this, add nuts, seeds, potatoes and broccoli to the diet.

Drug treatment of night blindness consists in the use of vitamins and special drops to improve vision. Often, the drops contain vitamin complexes that have a positive effect on the retina.

Traditional medicine provides for the elimination of hemeralopia in the following ways:

drink fish oil three times a day;
take a rosehip decoction.

It is possible to treat the disease surgically only if hemeralopia manifested itself in a person in a symptomatic form. Often, surgery is prescribed for patients with glaucoma. Thanks to prompt assistance, the patient regains his former vision at any intensity of illumination.

Diseases with similar symptoms:

Diabetes mellitus is a chronic disease in which the work of the endocrine system is subject to damage. Diabetes mellitus, the symptoms of which are based on a long-term increase in the concentration of glucose in the blood and on the processes accompanying an altered state of metabolism, develops, in particular, due to a lack of insulin, a hormone produced by the pancreas, due to which the body regulates the processing of glucose in body tissues and in his cells.

Or hemeralopia is a pathology, which is characterized by a sharp deterioration in visual acuity in poor lighting.

There is a deterioration in vision at night or at dusk, when moving from a lighted room to a dark one. As a result, a person's ability to navigate in space, the perception of yellow, blue colors is impaired.

Night blindness - what characterizes the disease

Night blindness is a disease in which there is a deterioration in vision in low light conditions. The development of pathology leads to a decrease in the threshold of sensitivity of the retina to light. The level of visual impairment depends on the properties of the retina.

There are several types of night blindness.

Congenital. Manifested since childhood. It develops with failures of metabolic processes in the body, fermentopathy. The congenital form of pathology is characterized by a gradual deterioration in vision. Orientation in space is disturbed in poor lighting.
Symptomatic. It develops due to retinal dystrophy as a result of eye diseases. Pathology is accompanied by symptoms that are characteristic of a particular eye disease.
Essential. It occurs as a result of a deficiency in the body of vitamin A. This type is temporary. Appears with malnutrition, abuse of bad habits, diseases of the liver and gastrointestinal tract. For this form of pathology, the appearance of dark spots on the eyeball is characteristic.

The causes of this pathology

Various dysfunctions of the body can lead to a sharp deterioration in vision. The main causes of pathology are:

Osteochondrosis of the cervical region. As a result of spinal deformity, there is a deterioration in blood circulation, oxygen saturation of the brain and optic nerve.
Vegetative-vascular dystonia. The disease occurs with chronic fatigue, sleep disturbance, stressful situations. There are malfunctions in the work of the nervous system, which lead to the appearance of dark dots before the eyes.
Hypertensive crisis. Sharp jumps in blood pressure cause damage to the lower retina of the eyeball, increasing its sensitivity.
Lack of vitamins A, P2 (bioflavonoids), PP (nicotinic acid) in the body.
Diseases of the liver, gastrointestinal tract, cardiovascular system.
Metabolic disorders.
Improper diet, alcohol abuse.
Eye diseases: glaucoma, myopia.
Retinal pathologies: inflammation, detachment, pigmentary pathology.
Diseases of the optic nerve.
Taking medications that can destroy vitamin A.

Eye trauma and age-related changes can also lead to the development of night blindness.

What vitamin deficiency causes a problem

Night blindness can be either congenital or acquired. Lack of vitamins in the body can lead to the development of the disease. Pathology occurs with a lack of vitamin A, sometimes B2, PP.

The cause of beriberi is:

irrational nutrition;
fasting;
anemia;
dysfunction of the liver and gastrointestinal tract;
chickenpox;
rubella;
body intoxication.

The development of beriberi is accompanied by the occurrence of symptoms such as dry skin, sensitive, bleeding gums, hyperkeratosis. Deficiency of retinol (vitamin A) leads to softening of the membrane of the eyeball. After some time, erosions and sores appear on the surface of the eyes.

Avitaminosis leads to a disruption in the process of production and restoration of rhodopsin, the lack of which causes a deterioration in the sensitivity of the retina to poor lighting. A person who sees perfectly in the daytime becomes almost blind at night.

The patient is poorly oriented in space in poor lighting, there is a feeling of the presence of a foreign body in the eyes, dry eye syndrome develops, color perception is disturbed.

Symptoms of night blindness in humans

Symptoms of the disease manifest themselves depending on the causes of the development of pathology.

Characteristic symptoms in a person with night blindness (vitamin A deficiency symptoms):

fuzzy picture, the outlines of objects become blurry, fuzzy;
the perception of blue, yellow color worsens;
impaired coordination of movements;
inflammatory process of the mucous membrane of the eyeball;
dry skin, mucous eyes;
keratinization of the skin;
the appearance of ulcers on the cornea;
increased fragility of nails, hair loss;
bleeding gums;
sensation of the presence of a foreign body in the eyes;
narrowing of the field of view in poor lighting;
there is a need to increase the brightness of the light during the day while reading, writing;
a sharp deterioration in vision with a decrease in the brightness of light;
gray spots on the conjunctiva of the eyelids;
dark spots before the eyes.

A person who has a pathology of vision involuntarily changes his behavior. He becomes more careful, not in a hurry, avoids a sharp transition between bright light and a dark room.

As a result of the development of pathology in early childhood, children develop a fear of the dark. Before dark, they have a growing sense of fear, panic. Children become restless.

Correct diagnosis of the disease

The doctor can determine the cause of the deterioration in visual acuity, prescribe an effective treatment by prescribing diagnostic methods. First, the specialist conducts a visual examination of the visual organs, a survey of the patient.

The main diagnostic methods include:

Visometry. The quality of vision is determined using the Sivtsev table. For young children, use the Orlova table.
Ophthalmoscopy of the fundus. Helps to examine the optic disc, retina, blood vessels.
Tonometry. The amount of intraocular fluid, intraocular pressure is measured.
Biomicroscopy. Allows microscopy of the structure of the eyeball: anterior chamber, iris, cornea, lens, fundus.
Optical coherence tomography allows you to determine the state of the retina.
Perimetry is performed to determine the size of the field of view.
Adaptometry. Helps to set the level of light perception. A flash of bright light is directed into the eyes. Then the time period is measured to determine the level of adaptation of vision.
Electroretinography can detect retinal defects.

After the diagnosis, the ophthalmologist determines the diagnosis, prescribes treatment to eliminate the pathology.

The risk of disease

Night blindness often occurs as a consequence of another eye disease. The lack of effective treatment with a simultaneous deficiency of vitamin A leads to the development of undesirable complications.

The nature of the consequences that occur with pathology depends on the causes of its occurrence: glaucoma, optic nerve atrophy, retinal pathology, myopia.

In some, with the development of night blindness, psychological disorders are observed, because loss of vision, a sense of uncertainty negatively affect the psyche. There may be a fear of the dark, they are poorly oriented in space in poor lighting, often get into an accident.

As a result of metabolic disorders, there is a deposition of iron salts in the organs of vision (siderosis of the eye), which leads to pigmentation of the cornea, the optic nerve head.

In the complete absence of treatment, pain syndrome can develop, tearing increases, the eyes quickly get tired with minimal stress. If the disease is caused by genetic factors, it can be transmitted from parents to children.

In the initial stages of the development of the disease, it can be eliminated with the help of drug therapy. Further development of the pathology leads to severe complications, which can lead to complete loss of vision.

Effective treatment of the disease

Therapy for night blindness depends on its forms and causes. There are several methods of treatment.

Medical therapy. The patient is prescribed a course of vitamins A, B2, PP. The doctor also prescribes ophthalmic vitamin solutions and drugs for the treatment of a provoking disease. They contribute to the rapid saturation of the retina with vitamins.
Surgical intervention. With symptomatic hemeralopia, therapy consists in eliminating the underlying eye disease. Refractive surgery is performed when replacing the lens, skeroplasty. Myopia is corrected with laser correction. For the treatment of cataracts, glaucoma, trabeculectomy, trabeculotomy, phacoemulsification are performed. Retinal detachment is treated with laser photocoagulation.

In combination with traditional therapy, folk methods are used:

In 0.5 liters of boiled water, add 3 tablespoons of wild rose. The mixture should be boiled for 10 minutes, infused for at least 12 hours. The finished medicine is taken 1-3 cups three times a day. The course of therapy is 1 month.
Combine lingonberries, blackberries, primroses, raspberries, lemon balm, serpentine mountaineer root in equal amounts. Pour 350 ml of boiling water over a teaspoon of the vegetable mixture. Insist 1 hour. Ready infusion to drink ½ cup 3 times a day.

Dietary nutrition will help speed up the healing process. In the daily diet, it is necessary to include foods that are a source of vitamin A.

Proper prevention and prevention of the disease

To speed up the process of recovery, to prevent the re-development of the pathology, preventive measures will help:

Balanced diet. Include foods that contain vitamin A in your daily diet. These include: cod liver, butter, dairy products, eggs, fruits, berries, vegetables, greens.
Healthy sleep. It is necessary to observe the sleep pattern. Night rest should be at least 8 hours. Go to bed and get up preferably at the same time every day.
Moderate physical activity. When playing sports, physical labor, it is necessary to avoid heavy physical exertion.
Walks in the open air. Hiking in the open air contributes to the saturation of the body with oxygen, the activation of metabolism, and the general strengthening of the body.
Wear sunglasses. Eyes must be protected from bright sunlight, blinding light from car headlights. It is not recommended to look at the snow in sunlight.
Proper lighting of the workplace when working at a computer for a long time.
Observe the rules of hygiene. It is necessary to avoid getting into the eyes of a foreign body, dust, microbes. After visiting public places, walking in the fresh air, contact with sick people, pets, you should wash your hands.
Every day you need to drink about 1.5 liters of purified water. This volume of fluid contributes to the normalization of the water-salt balance in the body.
Timely treat colds, viral, infectious diseases.

If the first symptoms of an eye disease develop, you should immediately contact an ophthalmologist.

Why is the disease so named?

Hemeralopia is popularly called night blindness. The disease got its name as a result of the similarity of the human retina in hemeralopia with the retina of chickens. The retina of the human eyeball consists of "cones" and "rods".

"Cones" are the elements with which a person has the ability to distinguish colors and shapes of objects. "Sticks" perform the function of light perception.

The retina of chickens consists only of "cones". Therefore, animals are not able to see in the dark. As a result of the development of pathology in humans, there is a deformation of the retina, in which dysfunctions of the "rods" are observed. As a result, a person loses the ability to distinguish shapes, colors of objects in poor lighting.

If you experience characteristic symptoms of the development of pathology, you should consult a specialist. Do not resort to self-medication.

Incorrect, untimely therapy can lead to the development of undesirable consequences and complications. It can cause complete loss of vision.

Treatment with folk remedies

Alternative treatment of night blindness consists in the use of various decoctions, infusions and juices and other preparations from plants and products containing vitamins A, PP and B2, which are necessary for the normal functioning of the eyes.

So, the following infusions, juices, decoctions and gruels are effective folk methods for treating night blindness:

Mix 2 parts of blueberry leaves, linden flowers and dandelion (leaves, root and flowers), add 1 part of buckwheat and sea buckthorn leaves. Pour a tablespoon of the finished mixture of herbs with a glass of boiling water and heat in a water bath for 15 minutes. Then insist in a warm place for half an hour, strain and take the finished broth one glass three times a day after meals.
Pour a teaspoon of the flowers of the field color plant with a glass of boiling water and leave for 10 minutes. Ready infusion take a tablespoon three times a day after meals.
Pour a teaspoon of blue cornflower flowers with a glass of boiling water and insist for one hour. Strain the infusion and take 1/4 cup three times a day half an hour before meals.
Pour one tablespoon of blueberries with a glass of boiling water and insist for four hours. Strain the finished infusion and take half a glass three times a day, regardless of the meal.
Sea buckthorn berries should be consumed fresh or frozen, two glasses a day.
Pour three tablespoons of sea buckthorn berries with a glass of boiling water and insist for half an hour, then strain. Ready infusion to drink twice a day an hour after a meal. You can add honey or sugar to the infusion to improve the taste.
Pour two tablespoons of leaves and tops of the nettle stalk with a glass of boiling water, insist for an hour, then strain. Ready infusion take 1/3 cup three times a day half an hour before meals.
Take juice from fresh carrots in half or a whole glass 2-3 times a day half an hour before meals. Juice should be prepared immediately before use and stored for no more than 30 minutes.
Blueberry juice taken diluted three times a day before meals. For each dose, you need to dilute a tablespoon of juice in half a glass of water.
Grape juice to take half a glass three times a day for half an hour before meals.
Germinate wheat grains, then grind them in a meat grinder. Pour a tablespoon of gruel from germinated wheat grains with a glass of boiling water and heat in a water bath for half an hour. Then insist 15 minutes, then strain. Ready broth to take 1/3 cup three times a day, regardless of the meal.
Fish oil take 30 - 40 ml three times a day; Eat a small piece of lightly fried beef liver every day.
Sea buckthorn oil take a teaspoon three times a day before meals. Before use, you should consult with a specialist.

Eye drops for hemeralopia

To maintain reduced vision, it is recommended to use Riboflavin drops (vitamin B2). This multicomponent complex will enrich the tissues of the organs of vision with oxygen, facilitate the conduction of nerve impulses in the retina. The complex is prescribed for keratitis, iriditis, night blindness and conjunctivitis.

Drops are instilled one in each eye 2 times a day. Duration of admission - from 5 to 15 days. The drug is contraindicated for patients who have intolerance to the constituent components of Riboflavin.
