How infectious diseases affect the health of the eye

Infectious diseases of the eye Damage to visual functions is often manifested as a consequence of infectious diseases. In some cases, this is an integral sign of infection. In other circumstances, eye diseases result from the addition of a secondary infection. Frequent complaints with lesions of an ophthalmic nature are pain when moving the eyeballs, hemorrhage in the conjunctiva, as well as other symptomatic manifestations. Consider the effect of some infectious diseases on the condition of the eyes.

What do rubella and chickenpox do to your vision?

In a special symptomatic group, classic syndromes of congenital rubella are distinguished. They represent the unity of three characteristics that affect individual organs. These are cataracts, deafness and heart defects. This trio was called the Gregg Triad. If rubella occurs after birth such variants of the development of an ophthalmic picture are possible:

detection of catarrhal conjunctivitis, which is often combined with inversion of the eyelids;
the diagnosis of catarrhal conjunctivitis, with the accompanying point keratitis;
the development of retinopathy, which entails retinal edema.

Infectious diseases of the eye Redness can be accompanied by inflammation of the lacrimal glands, clouding of the cornea. In some cases, there are birth defects, for example, a decrease in the size of the eyeballs. Pathological processes that develop in the body with rubella can trigger retinal degeneration.

In chickenpox, the blisters characteristic of the disease appear not only on the body, but also on the conjunctiva or cornea. Later, inflammatory processes develop, affecting the iris, the ciliary body of the eyeball.
How big are the effects on the eyes of viral infections

Any infection can negatively affect the ability to see. The difference lies in how it manifests itself in ophthalmology – what symptoms it is accompanied by and what consequences it leads to.
When infected with the herpes virus

The herpes virus after infection of the body remains in it forever. It provokes the development of chronic diseases, which periodically worsen. One of the forms of infection is ophthalmic herpes. If it is obtained in utero, then at birth it is expressed in the form of cataracts or chorioretinitis. Such conditions are triggered by the fact that the fetus is affected by toxoplasmosis or cytomegalovirus. At birth, the disease is diagnosed only in 10% of cases.

Most often, secondary forms of the disease are detected in children starting from 3 years of age or in adult patients. Signs of infection occur when:

sudden changes in temperature (overheating, hypothermia);
frequent stress;
excessive exposure to the sun;
hormonal disorders;
chronic infections;
surgical treatment.

Infectious diseases of the eye-ophthalmic herpes can be provoked by acute respiratory viral infections, lack of vitamins, and decreased immunity. In this case, the front camera of the eye most often suffers. Conjunctivitis, blepharitis, keratitis, corneal erosion or deeper lesions are diagnosed, which are expressed in the formation of ulcerative processes. If the infection affects the posterior chamber of the eye, the retina and optic nerve suffer. At the same time, necrosis of the tissues of the visual organs, neuritis, retinopathy are noted.
In the case of prenatal cytomegalovirus infection

This infection affects the condition of the posterior chamber of the eyes. In more rare cases, there are such concomitant diseases as cataracts, iridocyclitis, hypoplasia and other pathologies. The cornea and optic nerve are affected. A characteristic manifestation of prenatal cytomegalovirus infection in adult patients is a decrease in local immunity. The first signs of this phenomenon are inflammation of the vessels of the visual organs and hemorrhages that are provoked by it.
During the spread of Staphylococcus

If inflammatory processes appear on the eyelids, this may indicate infection with Staphylococcus. Harmful microflora manifests itself, provokes the formation of barley, blepharitis or abscess. It triggers the development of uveitis and keratitis, which appear after surgical interventions, causes chronic inflammatory damage to the conjunctiva.
What eye complications do toxoplasmosis and scarlet fever cause?

With scarlet fever, conjunctivitis is diagnosed, which affects the inner surface of the eyelid or with weakened immunity extends to the sclera. If the disease is severe, the inflammatory process passes to the cornea. In this case, ulcers and damage to the ciliary body or iris can form.

The ophthalmic manifestation of toxoplasmosis depends on the type of disease. Congenital disease causes underdevelopment of the eyeballs. Most often, both or one of them is smaller in size than in healthy people. In rare cases, the eyeballs are missing. Among other pathologies, there are scarring between the retina and vascular membrane, as well as malformations of the optic nerve. In the case of acquired toxoplasmosis, the inflammatory process affects the vascular or iris, the ciliary body.
Diphtheria, measles and mumps also affect vision

Infectious diseases of the eye With a decrease in immunity, the human body can not cope with the bacterial load and it can be overtaken by infection with a rod-shaped bacterium that causes diphtheria. In some cases, the conjunctiva is affected. In this case, ophthalmic diphtheria can occur in the following forms:

catarrhal;
filmy;
toxic.

Filmy diphtheria of the eyes is characterized by pronounced signs with the formation of visible edema of the eyelid. At the same time, a cloudy liquid with purulent inclusions is released from the eyes. A grayish film forms on the conjunctiva. If you try to remove it, the damaged area will bleed. The films are gradually rejected by themselves, and in their place there are star-like scars. In severe cases, there is a fusion of the conjunctiva of the eyelid and the eyeball. A sign indicating the possibility of developing this pathology is the appearance of infiltrates on the cornea, which then turn into ulcers. Symptoms of toxic diphtheria of the eyes include:

puffiness of the eyelids;
the secretion of lymph and pus;
formation of films on the eyes;
the appearance of irritation and wet areas on the skin around the eyes.

Measles is accompanied by conjunctivitis and photophobia. Recognize this disease among others will help such a sign as the appearance of white spots on the back of the eyelids. The cornea is affected by an inflammatory process that disappears after a few days. With a severe course of the disease, ulcers are found in the eyes, inflammation of the iris begins. Without proper treatment, pathological processes capture the fundus. The formation of exudates and hemorrhages is noted.

Mumps also, like most other infectious diseases, provokes inflammatory processes that spread to the visual organs. They affect the lacrimal glands, conjunctiva, sclera, cornea, and iris. Taking into account the degree of prevalence of pathological processes, a competent doctor in infectious diseases can refer the patient to an ophthalmologist in order to conduct studies that exclude the spread of pathogenic cells to the visual organs.
