Parasites in the human body are capable of migrating and the focus of localization is located in any part of the body. Some types of helminths settle in the eyes, causing inflammation, cysts and visual impairment. Why are parasites dangerous in the eyes of a person, symptoms and treatment methods in one article.

Features of helminthiasis of the organs of vision

Parasites enter the organs of vision, migrating from the intestines, or self-infection occurs. The helminth can get directly into the human eye through the bite of an insect that carries eggs through personal hygiene items. Migration is associated with an acute form of invasion.

The wrong treatment is selected for a person and parasites, feeling discomfort, are forced to leave the intestines. During migration, worms affect other organs, harming health. Some species move to the eyeballs, eyelids and mucous membranes. Parasites cause acute eye disease.

There are two forms of ocular helminthiasis:

  • External - when the parasite larva settles in the lacrimal sac or in the conjunctiva;
  • Internal - when a parasitic agent settles inside the eyeball.

According to the degree of destruction of the organ of vision by parasites, the external form of helminthiasis is divided into types:

  • The eyeball is destroyed;
  • The eyelid zone is damaged;
  • Larval conjunctivitis;
  • Disrupted activity of the optic nerve;
  • Convective granuloma.

The internal form of infection is subdivided according to the location of the parasite in the eyeball:

  • Back infection;
  • Front part infection.

Helminths easily penetrate the organs of vision from the ear and nasal passages.

Symptoms

When infected with ocular helminthiasis, symptoms may appear immediately or the development of the parasite may occur after a few weeks. The period from infection to the development of a parasitic agent is called incubation.

At the initial stage, the patient manifests symptoms:

  • There is a sharp, cutting pain;

    Image

  • The release of tear fluid increases;
  • Inflammatory process of the eyelids and conjunctiva;
  • Purulent discharge;
  • Slight hyperthermia by 1–3 degrees;
  • Acute attacks of headache.

After the death of the parasite, the human body experiences intoxication, nausea and chills appear

The mucous membrane of the organs of vision reacts very quickly to foreign agents, and the pain symptom appears already in the first few hours after infection. The eye itches, it tingles, there is a feeling of a foreign body inside.

At the first signs of helminthiasis, you should not delay the trip to the specialists. The ophthalmologist will examine the diseased organ and remove the parasitic agent or prescribe appropriate treatment.

Types of diseases and their treatment

There are several types of helminths that most often affect the organs of vision. Depending on the type of parasitic agent, a person develops diseases:

  • Echinococcal infection;
  • Opisthorchiasis;
  • Dirofilariasis;
  • Ophthalmomyiasis, external and internal.

Each type of disease has its own symptoms and requires treatment according to a specific scheme.

Echinococcal infection

Initially, echinococcus settle in the human intestine, but the larvae of the parasite penetrate the bloodstream. The parasite travels through the vessels to other human organs: eyes, muscles, kidneys and liver.

Echinococcus affects the organs of vision only in acute invasion, when helminthiasis is started.

With eye damage, the patient shows symptoms:

  • Difficulty blinking;
  • The eyelids are swollen and inflamed;
  • The skin on the eyelids becomes thin and dry;
  • The presence of a foreign object is felt in the eye;
  • The eye stops closing completely;
  • The mucous membrane dries up;
  • Vision is impaired, objects are double;
  • Lacrimation increases.

At the initial stage of the disease, conjunctivitis develops, which turns into partial loss of vision and bulging. The expulsion of the eyeball is due to the growth of cysts inside the mucous membrane. There is pressure from adjacent tissues and the eye is pushed out.

Therapeutic effects

Treatment of echinococcal infection should be started immediately. Traditional methods will only aggravate the situation. Therapeutic effect is given only by medications. They effectively cope with Pirantel and Dekaris disease. The drugs are analogous to each other and act on adult parasites, preventing their reproduction.

Additionally, funds from the chemotherapy group are prescribed: Ditrazin or Chloxil. A solution of drugs is injected into the formed cysts. It is possible to remove adult worms from human eyes only by surgery.

Opisthorchiasis

Initially, the parasite is localized in the liver, but with an acute invasion, the worm begins to migrate to other organs. The eyes are susceptible to damage in the first place, since the tissues of the organs of vision are delicate and like helminths. Opisthorchiasis proceeds without visible symptoms.

Secondary infection is dangerous, against the background of which adhesions develop. A person loses sight, at first partially and subsequently completely.

With the development of the disease, the patient has symptoms:

  • Damage to the vascular system in the shell of the eyeball;
  • Hemorrhage;
  • Neuritis of the organ of vision;
  • Keratitis of the optic nerve.

Hemorrhage occurs due to damage to the vascular system by the parasite. The worm does not cause pain symptoms and the person turns to a specialist late.

Therapeutic effects

Treatment of opisthorchiasis is carried out with medication. The patient is prescribed drugs: Praziquantel, Chloxicol or Albendazole. Since the main source of localization of the parasite is in the liver, choleretic drugs are prescribed in parallel: Tsikvalon, Hofitol.

After death, the remains of the parasite's vital activity remain in the human body, they can cause an allergic reaction. Any antihistamines will help relieve symptoms.

Dirofilariasis

The disease is caused by a worm from the Nematoda class. The parasite lodges under the skin of a person and can migrate throughout the body. A nematode enters the human body when bitten by a mosquito. The larva penetrates the skin, and for some time behaves without visible manifestations.

After a certain time, the worm dies on its own, since one sexually mature individual usually settles in the body. But there are cases of infection by several nematodes at the same time.

When the worm enters the eyeball, the patient has symptoms:

  • Rapid blinking;

  • Swelling and redness of the eyelids;
  • The eye does not close well;
  • The mucous membrane dries up;
  • Pain in bright light;
  • Vision deteriorates;
  • A small nodule forms on the eyelid or mucous membrane.

After the death of the parasite, a person experiences chills, nausea.

Treatment

When infected with dirofilariasis, no medication will help. The person is assigned an operation to remove the worm. After the operation, the patient is prescribed antibiotics, anti-inflammatory and antihistamines.

Ophthalmomyasis, external and internal

The disease causes infection by the fly larva from the gadfly family. The larva settles under the skin and penetrates any part of the body.

With external infection, a person shows symptoms:

  • Larval conjunctivitis;
  • Inflammation of the eyelid;
  • The eye festers and hurts.

Symptoms of external infection appear after the larva enters the conjunctival sac

Symptoms with internal damage to the eyeball are more complicated:

  • Vision deteriorates sharply;
  • Sharp pain in the eyes;
  • Inflammatory process.

If the larva enters the eyeball, a person may develop a granuloma. In some cases, a person feels how the larva moves inside the eye. Without timely treatment, the patient quickly loses his sight.

Therapeutic effects

Treatment is selected individually and depends on the form and severity of the disease. With the external form of myiasis, antibiotics and antihistamines are prescribed. Live larvae are removed surgically. The damaged tissue of the lid mucosa is also removed.

For internal lesions, only surgical treatment is available. After the operation, 70% of patients develop a bactericidal infection, since the worm left the products of its vital activity inside the apple. Vision will be lost partially or completely. After surgery, the patient is prescribed a course of strong antibiotics.

Medical treatment of helminthiasis is carried out in two stages. In the first dose, adults are neutralized, during the second course, new larvae die, which will appear in the body after treatment.

The specialist will tell you more about the treatment regimen for each disease, since in each case the individual characteristics of the patient's health and the form of the disease are taken into account.

Preventive measures

Any person can be exposed to ocular helminthiasis. But the risk group includes people who do not follow simple rules:

  • It is necessary to thoroughly wash your hands or treat them with an antiseptic after contact with animals, vegetables in supermarkets, and the ground.
  • Treat nails from dirt daily with a special brush and soap.
  • Children should have their nails cut at least once a week.
  • Before using vegetables or herbs, they must be rinsed under running water. It is advisable to wash large fruits with laundry soap.
  • Do not drink unboiled water from a tap or open source.
  • Meat products should only be purchased in trusted locations where the product is checked by a veterinarian before being sold.
  • The spread of rodents and insects in the house is not allowed.
  • Once every six months, all pets are treated for helminths.
  • If there are animals in the house, then once a year the whole family should undergo preventive treatment for parasites.

Folk recipes can be used as preventive measures. The following herbs effectively fight parasites: tansy, wormwood, cloves, ginger. Natural ingredients have an unpleasant bitter taste. To improve the taste and prevent the migration of worms, it is recommended to mix herbs with natural honey and lemon.

Ginger, which is taken in natural or pickled form, effectively fights against worms. It is recommended that the whole family drink pumpkin seed oil once a year. The taste of pumpkin is not to the liking of parasites and they leave the human body.

Be wary of traditional methods for acute invasion. A large number of worms will be forced to migrate throughout the body and parasites from the intestines will easily pass into the eyes, muscles and other organs.

Helminthiasis of the eyes is a dangerous disease. When affected by some types of worms, a person loses his sight and remains disabled for life. Treatment should be started from the first days of the onset of symptoms, this is the only way to avoid harmful consequences.
