Purulent conjunctivitis urticaria. Why the conjunctiva becomes inflamed, types of allergens. Drug-induced conjunctivitis in a child

A very important classification that makes it easier to find information is ICD-10; conjunctivitis is also on this list. It causes inflammatory processes in the mucous layers of the eye. Usually a person experiences discomfort, pain, increased lacrimation, photophobia, redness, and itching.

ICD-10 is an international document that includes a classification of various diseases and other human health problems. This document is recognized in every country. Every 10 years it is reviewed and supplemented. This is what the World Health Organization does. The document is now in force after its tenth revision.

Conjunctivitis is also listed in the ICD-10 system. This disease is numbered H10. However, conjunctivitis has many varieties. For example, if conjunctivitis is distinguished by the secretion of mucus and pus, then in this case the code will be H10.0. If the disease has an acute atopic form, then the code will be H10.1. Other acute forms of the disease are listed under number H10.2. If conjunctivitis is acute, but unspecified, then its number is H10.3. In the chronic form of conjunctivitis, the number H10.4 is established. For blepharoconjunctivitis there is a code numbered H10.5. For other forms of this disease, code H10.8 is used. And if the disease could not be clarified, then the number H10.9 is written.

Other diseases of the conjunctiva also need to be taken into account. They have code H11. For pterygium there is code H11.0. If the patient has conjunctival deposits or even degeneration, then this pathology has the number H11.1. If the patient has conjunctival scars, then the code is set to H11.2. For conjunctival type hemorrhage there is code H11.3. Other conjunctival vascular diseases and the presence of cysts are numbered as H11.4. for other specified diseases of the conjunctiva, the code is H11.8. If the disease of the conjunctiva is not specified, then code H11.9 must be entered.

The clinical picture depends entirely on the causes of the disease and its form. There are two main forms. Firstly, the acute form, it is characterized by the sudden appearance of symptoms of the disease. The eyes quickly turn red, severe pain and itching appear. Sometimes pinpoint bleeding is noticeable. The eyelids swell and discharge appears from the eyes. Secondly, the chronic form, in which inflammation usually spreads to both eyes. The course of the disease is very sluggish, the clinical picture develops gradually. Typically, this form occurs in other chronic diseases in the human body. In addition, there are several types of the disease:

Viral. Usually develops together with herpes or other viral diseases. Frequent symptoms are severe itching and lacrimation. By the way, the mucus that comes out of the eye is purulent in most cases. The inflammation quickly spreads to both eyes. In addition to such symptoms, you can also notice a runny nose, sore throat, and low-grade fever.
Bacterial. Usually caused by staphylococcus, streptococcus, gonococcus, pneumococcus. The peculiarity is that the discharge has a gray or cloudy purulent tint. They have a very viscous consistency, which causes the eyelids to stick together, especially after the patient has slept. The skin around the eyes is also affected.
Fungal. Develops due to exposure to fungal microorganisms on the mucous membranes. Typically these are actinomycetes, molds and yeasts.
Allergic. Manifests itself as an allergic reaction to something. Characterized by severe pain, burning and itching. Typically, additional symptoms are bronchial asthma and runny nose. If you do not come into contact with the allergen, these symptoms quickly disappear on their own.
Chemical. In this case, conjunctivitis is caused by toxic or chemical substances that enter the person's eyes. He will complain of severe pain in his eyes, but there are simply no other symptoms.
Drug. This form is caused by the use of various medications that have caused side effects. Usually, symptoms of conjunctivitis appear in the first 6-8 hours after taking the drug. The clinical picture develops quite quickly, a burning sensation and copious mucus discharge appear.

Therapeutic measures

Before starting treatment for conjunctivitis, it is necessary to find out the causes of the disease. Thanks to this, therapy will be more effective. This disease can be treated by an ophthalmologist. Under no circumstances should you resort to self-medication, because... this may make the situation worse. The main treatment is drops, so the therapy will be local in nature.

Treatment of viral conjunctivitis. If a person’s conjunctivitis is caused by a viral infection, then it is necessary to use drops with antiviral properties. The most commonly used drugs are from the interferon group. If the disease has a generalized form, then medications in tablet form must be prescribed. If severe itching occurs, the doctor prescribes corticosteroids in the form of drops. Unpleasant sensations will quickly pass thanks to this drug. In addition, to remove pronounced symptoms, special artificial drops are prescribed. If a viral infection is also accompanied by a bacterial agent, then antibiotics cannot be avoided.
Treatment of allergic conjunctivitis. If the disease is caused by an allergic reaction, then it is necessary to use drugs from the group of steroids. However, they are used only if the patient's condition is very serious. To eliminate the feeling of severe itching, drops with antihistamine properties are used. To relieve inflammation, it is necessary to use non-steroidal drugs with anti-inflammatory properties. If you suffer from severe dry eyes, then synthetic drops are used. It is imperative to take products from the anti-allergenic group. For example, Claritin, Tavegil, Suprastin are suitable. For topical use, hormonal agents such as hydrocortisone or prednisolone are suitable.
Treatment of bacterial conjunctivitis. Antibacterial therapy is mainly used. The doctor must select topical antibiotics for the patient - these are drops and ointments. For example, erythromycin, gentamicin or tetracycline ointment is suitable. In addition, drugs from the fluoroquinolone group are used.

The code for conjunctivitis in ICD-10 is H10. However, it is necessary to take into account the various forms of this disease, which have a more detailed code. Almost everyone knows this disease. Unpleasant sensations in the eyes, lacrimation, discharge from the eye, photophobia - almost every person has experienced such symptoms at least once in their life. The causes of this disease are very different. It could be a viral or bacterial infection, an allergic reaction, etc. Treatment is quite simple. It is prescribed depending on the causes and symptoms. It is best to consult your doctor in advance before resorting to taking medications.

Conjunctivitis is an inflammatory process that affects the mucous membrane of the eye, which protects the sclera and inner eyelid from damage.

The disease is very common among children. The most common cause is poor hygiene, especially in children over one year of age who are already beginning to actively explore the world.

Description of eye disease, code according to ICD-10

Conjunctivitis - inflammation of the conjunctiva, the transparent thin mucous membrane of the eye. According to the international classification of diseases, this disease corresponds to code H10.

The disease develops under the influence of pathogenic microorganisms and most often occurs in an acute form. The symptoms are not too striking, but they are easy to recognize.

Depending on the nature of the cause that provoked the disease, it can be viral, bacterial and allergic.

You will find even more information about eye disease such as conjunctivitis in these articles:

Possible consequences, complications

The disease is dangerous because it can provoke complications. One of them is visual impairment.

After conjunctivitis, color vision may deteriorate When a child confuses colors, he does not perceive shades. But this rarely happens.

The most common consequence is transition of the disease into a recurrent chronic form or a protracted disease. Then children constantly need medications to relieve unpleasant symptoms.

The consequence may be suppuration. In this case, the disease is mild.

With a viral type of disease, within 5-7 days from the moment of infection, the body develops immunity against the infection, and the disease passes without a trace.

Among the reasons for the recurrence of conjunctivitis in a child, poor immunity, poor hygiene, and a tendency to allergic reactions should be noted.

You will learn about the causes and methods of treating conjunctivitis in children from the famous doctor Komarovsky from this video:

Prognosis and prevention

The prognosis is determined by how timely treatment is started. It is almost always favorable, since irreversible changes do not occur.

Negative consequences are possible if the inflammatory process affects the cornea, then vision may deteriorate.

The main preventive measures come down to hygiene. Teach your child to wash their hands and not touch their face or eyes with their hands. It is important to maintain, strengthen the immune system, and eat right.

The child must have individual hygiene and household items(dishes, towel). If he attends a kindergarten or school, then during the period of illness he must be isolated from other children.

To prevent conjunctivitis in young children in kindergarten, healthy children also need isolation from the sick person, because viral conjunctivitis is very contagious.

Conjunctivitis is not a very dangerous disease. It is important to treat it promptly and correctly, following the doctor’s recommendations.

Do not self-medicate, treat the baby’s condition responsibly, then the disease will pass without a trace.

In contact with

ICD 10 conjunctivitis is a disease that causes inflammation of the mucous membrane of the eye. Its signs may be redness, itching, irritation, pain when exposed to rays of light, excessive tearing for no reason, etc.

Like most diseases, conjunctivitis is included in ICD 10, the international medical classification of diseases. It is confirmed by the relevant document and is used throughout the world.

How to find conjunctivitis according to ICD

In the international classification, conjunctivitis corresponds to code H10. Moreover, as is known, this disease has several varieties, which are also listed in the ICD:

H10.0 – purulent;
H10.1 – ;
H10.2 – all sharp;
H10.3 – acute, unspecified;
H10.4 – chronic;
H10.5 – ;
H10.8 – others;
H10.9 – unspecified.

A number of conjunctivitis not listed in this list are designated in international documentation using codes H10–H13, depending on the characteristics.

The ICD classification allows doctors and pharmacists from different countries to determine the disease and methods of its treatment, which allows them to use treatment methods that have already been proven in practice. And it is also used when released for export by some countries, and by others when purchased and used, knowing in what case they should be used.

Types and characteristics of the disease

Like other diseases, conjunctivitis comes in two forms:

spicy;

The acute form occurs suddenly and is characterized by a sharp manifestation of symptoms, severe pain, pain, redness and itching. Chronic, on the other hand, involves repeated manifestations of the disease, and its course is not as pronounced as in the first case. In this case, both eyes become inflamed, and symptoms appear gradually.

Conjunctivitis is also divided into the following types:

Viral disease develops, as a rule, in parallel with other viral diseases, progresses quickly and affects both eyes, is characterized by profuse lacrimation and purulent discharge, and can also be accompanied by damage to other otorhinolaryngeal organs.
Bacterial is a consequence of damage by coccal bacteria, is distinguished by purulent grayish discharge, due to its thick consistency the eyelids stick together, and also affects the skin around the eyes.
Fungal is a consequence of the effect of fungi on the mucous membrane.
An allergy is caused by an allergenic irritant and may be accompanied by damage to the mucous membrane of the respiratory tract.
Chemical appears as a result of damage to the mucous membrane by toxic substances; the only symptoms present are pain.
Medicinal is a side effect of the use of certain medications, symptoms include burning and lacrimation.

This classification is used when establishing a treatment method, which depends on the form and.

Treatment of the disease

Treatment of each type of conjunctivitis has its own characteristics. If an allergic or medicinal type manifests itself, it is necessary to limit contact with the allergen, which will lead to a weakening of the symptoms, and subsequently complete relief from them. If it is impossible to interrupt contact, antihistamine blockers are used.

Important! Despite the fact that conjunctivitis, code H10 according to the ICD, is a common disease, you should never self-medicate. If any symptoms occur, be sure to see a doctor.

Viral types are treated with special drops, but in addition, do not forget that, as a rule, in this case, conjunctivitis has concomitant diseases, which should also be gotten rid of.

In the case of bacterial diseases, the doctor must prescribe medications that attack the source of the problem, and ointments are used to relieve symptoms. Fluoroquinol drugs are also used.

Conjunctivitis is one of the most common eye diseases. Today it is difficult to find a person who has never encountered the symptoms of this insidious disease. Treatment of conjunctivitis is complicated by the fact that viruses, fungi or bacteria can affect its development. So before prescribing treatment, you need to accurately determine the nature of the pathology.

Definition of disease

Acute conjunctivitis is an inflammatory process that affects the mucous membrane of the eye due to allergies or infections. The acute form of the disease is characterized by pronounced symptoms, which appear suddenly, and with proper and timely treatment, quickly go away.

Depending on the cause of the disease, conjunctivitis can be of the following types:

Taking into account which pathogen influences the development of conjunctivitis, the further treatment regimen is determined.

Causes

The development of infectious conjunctivitis can be affected by:

Among viral pathogens, the most common remain:

adenovirus infection,
herpes virus,
measles virus

If we are talking about bacterial conjunctivitis, then its development is influenced by the following agents:

staphylococci,
pneumococci,
coli,
streptococci,
diphtheria bacilli,
gonococci,
Koch's sticks.

Allergic conjunctivitis can occur under the influence of allergens such as medicine, household chemicals, and cosmetics. A pathological process can occur when the mucous membrane of the organ of vision is influenced by physical and chemical factors, or the presence of a chronic disease.

Symptoms

Acute conjunctivitis can be recognized by the presence of the following symptoms:

burning, pain in the eyes;
increased secretion of tear fluid;
hyperemia of the mucous membrane;
hypersensitivity to light sources;
purulent discharge;
weakness;
dizziness;
rise in body temperature.

It happens that when one eye is affected, the infection spreads to the second, which makes the situation worse.

Possible complications

If you do not start treatment for acute conjunctivitis caused by chlamydia, this can lead to deformation of the eyelids and pathology of eyelash growth. If the development of the disease is influenced by other bacteria, the following complications may occur:

meningitis;
sepsis;
otitis.

In newborns, eye diseases may progress after conjunctivitis. . The result of an adenovirus infection can be clouding of the cornea and disruption of the tear film. The most common complication of the allergic form of conjunctivitis remains its chronicity. After frequently recurring herpesvirus conjunctivitis, scars remain. The infectious form of the disease can lead to keratitis - inflammation of the cornea.

Diagnostics

Acute conjunctivitis can be diagnosed in several ways. An accurate and complete result can only be obtained after an external examination of the patient using a slit lamp. When making a diagnosis, it is important to understand the medical history. The patient should carefully tell the doctor about the symptoms he is experiencing.

Additional diagnostic methods include:

conjunctival culture;
smear or scraping examinations;
blood test, fluorography, chest x-ray(if there are accompanying symptoms). Conjunctival culture

Treatment Medicines

The doctor will be able to prescribe treatment only after an accurate diagnosis. It is from the cause of the development of the pathology that the following treatment regimen can be determined:

Bacterial conjunctivitis. Antibacterial drugs in the form of drops are used for treatment. Drugs such as Levomycetin and Sulfacyl sodium remain effective. If mucus or pus is released from the eye, then it is necessary to use a solution of furatsilin (1:5000), potassium permanganate (1:5,000), 1% Oletethrin ointment for rinsing. The last drug must be applied to the eyelid 2-3 times a day.
Viral conjunctivitis. For treatment, human leukocyte interferon or interferonogens are prescribed. This includes Pyrogenal, Poludan. Place drops into the conjunctival sac 6-8 times a day. You can use ointments: 0.5% Florenal, 0.05% Bonafton.
Chlamydial conjunctivitis. Systemic administration of the following drugs is prescribed: Doxycycline, Tetracycline or Erythromycin.
Fungal conjunctivitis. Use local infusions of Nystatin, Levorin, Amphotericin B.

Tetracycline is used in the treatment of chlamydial conjunctivitis

Allergic conjunctivitis. Drops with a vasoconstrictor and antihistamine effect, corticosteroids, tear substitutes, and desensitizing drugs are prescribed.
Fungal conjunctivitis. For treatment, antimycotic ointments and drops are used - Levorin, Nystatin, Amphotericin B.
Dry eye syndrome. This pathological process develops as a secondary lesion of the lacrimal apparatus. They use artificial tear preparations – Oksial. Oxial is used in the treatment of dry eye syndrome

Drops for conjunctivitis

When treating conjunctivitis, the doctor must prescribe eye drops to patients. The following medications remain effective:

Bacterial form - Floxal, Ciprofloxacin. To get maximum results, you need to apply Tetracycline ointment to your eyelids.

Floxal is used in the treatment of bacterial conjunctivitis

If you use these drugs according to the indicated scheme, you can very quickly cure a mild form of conjunctivitis at home.

Allergic form. Use drops with an antihistamine effect - Lecrolin, Opatanol. In addition, hormonal ointments and drops are prescribed - Hydrocortisone eye ointment, Dexamethasone.
Viral form. Drops with an antiviral effect are prescribed. They should contain interferon - Poludan, Ophthalmoferon.

Poludan is used in the treatment of viral conjunctivitis

Often the infection can be of a mixed form, in which case the doctor prescribes a set of drops.

Folk remedies

In some cases, it is possible to treat conjunctivitis at home. In addition to the main therapy, the doctor may recommend using the following folk remedies:

Aloe. Pick fresh aloe leaves, wash, squeeze out the juice and soak cotton pads in it. Apply to eyes for 15 minutes.
Baking soda. Take 5 g of soda, 100 ml of water. Combine the ingredients and use the eye wash solution.
Barberry root. Take 5 g of raw material (powder), add 200 ml of water. Simmer on fire for 15-30 minutes. Use the decoction as a rinse or compress. Barberry contains berberine and antibacterial compounds.

After each procedure, the eyes should dry thoroughly and then rinse them with boiled water.

Bread. Apply cold bread to your eyes. This will reduce inflammation and stop itching.
Castor oil. You need to put 1 drop into each eye. Do this every day.
Chamomile. Take 10 g of raw material, pour 200 boiling water. Leave for 5 minutes, filter, cool and use for rinsing or compress. You can also take equal amounts of chamomile and eyebright. For 20 g of raw materials, a glass of boiling water. Use rinsing solution.
Canadian goldenseal. This plant effectively copes with infectious conjunctivitis, as it contains berberine. It is especially effective to use the drug in the treatment of streptococcal conjunctivitis. Take 20 g of raw material, pour a glass of boiling water. Use a filtered solution for a compress. You can also drop 2-3 drops into each eye daily.
Eyebright. This plant is in great demand in the treatment of various eye diseases. It has an astringent and antibacterial effect and relieves eye irritation. You need to take 10 g of raw material, pour 200 ml of boiling water. Filter, cool and use to wash eyes. Carry out the procedure 3-4 times a day.
Rusty elm. Apply a compress using slippery elm compress. It has a bactericidal, astringent, analgesic and antioxidant effect. Apply the compress to your eyes for 15 minutes.

If swelling is present, the bag can be moistened with cool water.

Prevention

IN The basis for the prevention of acute conjunctivitis is compliance with the rules of hygiene. It is important to wash your hands with soap, do not touch your face and eyes with your hands, and do not use other people’s cosmetics and personal hygiene products. But prevention of allergic conjunctivitis involves timely detection of the allergen. Next, you need to try to avoid contact with him.

Acute conjunctivitis is a disease that is characterized by unpleasant symptoms of a pronounced nature. To begin to fight the disease, it is necessary to understand the nature of the pathology. Completely different medications are used to treat allergic, viral and bacterial conjunctivitis.

Classification of pathology

Forms of the disease and characteristics

Viral. Usually develops together with herpes or other viral diseases. Frequent symptoms are severe itching and lacrimation. By the way, the mucus that comes out of the eye is purulent in most cases. The inflammation quickly spreads to both eyes. In addition to such symptoms, you can also notice a runny nose, sore throat, and low-grade fever.
Bacterial. Usually caused by staphylococcus, streptococcus, gonococcus, pneumococcus. The peculiarity is that the discharge has a gray or cloudy purulent tint. They have a very viscous consistency, which causes the eyelids to stick together, especially after the patient has slept. The skin around the eyes is also affected.
Fungal. Develops due to exposure to fungal microorganisms on the mucous membranes. Typically these are actinomycetes, molds and yeasts.
Allergic. Manifests itself as an allergic reaction to something. Characterized by severe pain, burning and itching. Typically, additional symptoms are bronchial asthma and runny nose. If you do not come into contact with the allergen, these symptoms quickly disappear on their own.
Chemical. In this case, conjunctivitis is caused by toxic or chemical substances that enter the person's eyes. He will complain of severe pain in his eyes, but there are simply no other symptoms.
Drug. This form is caused by the use of various medications that have caused side effects. Usually, symptoms of conjunctivitis appear in the first 6-8 hours after taking the drug. The clinical picture develops quite quickly, a burning sensation and copious mucus discharge appear.

Therapeutic measures

Treatment of viral conjunctivitis. If a person’s conjunctivitis is caused by a viral infection, then it is necessary to use drops with antiviral properties. The most commonly used drugs are from the interferon group. If the disease has a generalized form, then medications in tablet form must be prescribed. If severe itching occurs, the doctor prescribes corticosteroids in the form of drops. Unpleasant sensations will quickly pass thanks to this drug. In addition, to remove pronounced symptoms, special artificial drops are prescribed. If a viral infection is also accompanied by a bacterial agent, then antibiotics cannot be avoided.
Treatment of allergic conjunctivitis. If the disease is caused by an allergic reaction, then it is necessary to use drugs from the group of steroids. However, they are used only if the patient's condition is very serious. To eliminate the feeling of severe itching, drops with antihistamine properties are used. To relieve inflammation, it is necessary to use non-steroidal drugs with anti-inflammatory properties. If you suffer from severe dry eyes, then synthetic drops are used. It is imperative to take products from the anti-allergenic group. For example, Claritin, Tavegil, Suprastin are suitable. For topical use, hormonal agents such as hydrocortisone or prednisolone are suitable.
Treatment of bacterial conjunctivitis. Antibacterial therapy is mainly used. The doctor must select topical antibiotics for the patient - these are drops and ointments. For example, erythromycin, gentamicin or tetracycline ointment is suitable. In addition, drugs from the fluoroquinolone group are used.

What is common in the etiology of all forms of allergic conjunctivitis is increased sensitivity to various environmental factors. Due to the peculiarities of the anatomical structure and location of the eyes, they are most susceptible to contact with exogenous allergens.
Hay fever, pollen allergy) is a seasonal allergic conjunctivitis caused by pollen allergens during the flowering of grasses, trees, and cereals. Exacerbation of hay fever conjunctivitis is associated with the flowering period of plants in a particular region. Seasonal allergic conjunctivitis in 7% of patients worsens in the spring (late April - late May), in 75% - in the summer (early June - late July), in 6.3% - in the off-season (late July - mid-September), which accordingly, it coincides with the pollination of trees, meadow grasses and weeds.
The etiology of spring conjunctivitis has been little studied. The disease worsens in spring - early summer and regresses in autumn. This form of allergic conjunctivitis usually resolves spontaneously during puberty, which suggests a certain role of the endocrine factor in its development.
The main factor in the development of large-papillary conjunctivitis is considered to be wearing contact lenses and eye prostheses, prolonged contact of the mucous membrane with a foreign body of the eye, the presence of sutures that irritate the conjunctiva after cataract extraction or keratoplasty, calcium deposits in the cornea. In this form of allergic conjunctivitis, the inflammatory reaction is accompanied by the formation of large flattened lesions on the mucous membrane of the upper eyelid papillae
Drug-induced conjunctivitis develops as a local allergic reaction in response to topical (90.1%), less often systemic (9.9%) use of drugs. The occurrence of drug-induced allergic conjunctivitis is facilitated by self-medication, individual intolerance to the components of the drug, polytherapy - a combination of several drugs without taking into account their interaction. Most often, drug-induced allergic conjunctivitis is caused by the use of antibacterial and antiviral eye drops and ointments.
Chronic allergic conjunctivitis accounts for more than 23% of cases of all allergic eye diseases. With minimal clinical manifestations, the course of chronic allergic conjunctivitis is persistent. Direct allergens in this case are usually house dust, animal hair, dry fish food, feathers, fluff, food products, perfumes, cosmetics and household chemicals. Chronic allergic conjunctivitis is often associated with eczema and bronchial asthma.
Atopic keratoconjunctivitis is an allergic disease of multifactorial etiology. It usually develops during systemic immunological reactions, therefore it often occurs against the background of atopic dermatitis, asthma, hay fever, and urticaria.
