The disease is associated with a purulent type of conjunctival inflammation. The main symptoms are white or yellow pus, soreness, photophobia, edema of the eyelids, conjunctival redness. Purulent conjunctivitis in dogs is caused by bacteria and fungi. For recovery, qualified treatment with antibiotics is necessary.
Causes of the disease
The cause of the disease is only one - the reproduction of pathogenic microbes and fungi on the conjunctiva of the pet. Here you need to understand that the body is constantly confronted with pathogens, but usually it can destroy them on its own (that is, it has resistance). However, in some cases, resistance to infection decreases.
Among the predisposing factors, experts consider:
- conjunctival damage due to eye injury;
- chemical contact with the eye;
- infection in the eye with foreign bodies, such as sand, dust;
- infectious diseases of an endogenous nature;
- lack of vitamin A;
- burns or hypothermia;
- metabolic disease;
- eyelash ingrowth;
- any other eye diseases.
Dobermans, pugs, Pekingese, Yorks, bulldogs and mastiffs suffer from conjunctivitis more often than other dogs. In this regard, the owners of these breeds must carefully monitor the health of the eyes of the pet.
Symptoms of the disease
More often with a purulent form of conjunctivitis, inflammation develops in both eyes, but there are cases with damage to only one side. It is not difficult to determine the type of inflammation, but to establish the type of pathogen, it is necessary to take exudate from the conjunctiva.
Acute purulent conjunctivitis
In the acute form, the symptoms are as follows:
- swelling on the eyelids;
- fear of light;
- temperature rises;
- the conjunctiva turns red;
- severe soreness of the conjunctiva and eyelids.
But the most characteristic symptom is purulent discharge from the eyes. They are thick white or yellow. In the morning they glue the eyelids of the animal, which makes it difficult for him to open his eyes. Pus may have a slight admixture of blood, it accumulates on the inner corner of the eye, which causes wet eczema to form under it.
Chronic purulent conjunctivitis
The disease becomes less noticeable. Photophobia and pain may disappear, but the conjunctiva often becomes cyanotic (due to stagnation of blood). Part of the conjunctiva protrudes and ulcerates, necrotic. The pus becomes thick, gray-yellow in color with an unpleasant odor, its amount decreases.
With timely therapy, it is possible to avoid any complications. But if the animal is not treated, then the inflammation passes to the cornea and lacrimal ducts. As a result, the dog becomes blind, the disease is complicated by the formation of purulent follicles, sepsis. It is possible to save the life of a pet in such severe cases, but it will not be possible to restore vision. Treatment consists of symptomatic and specific therapy with the mandatory use of antibiotics.
Treatment may include local (ophthalmic) antibiotics and systemic antibiotics, which are prescribed for fever when the infection has already entered the bloodstream.
