redness of the mucous membrane of the eye and eyelids;
By cause of development, infectious and non-infectious forms are distinguished. The contagiousness of the disease, symptoms, and treatment tactics depend on the cause of inflammation.
Infectious conjunctivitis in the eye occurs due to viruses, bacteria, or more rarely fungi. This group includes:
- bacterial conjunctivitis — is often accompanied by mucopurulent or purulent discharge and pronounced redness of the eyes;
- viral conjunctivitis — often develops against the background of a cold or ARVI, may be accompanied by tearing, swelling of the eyelids;
- fungal — occurs rarely, mainly after eye injuries or with a significant decrease in immunity.
Infectious forms can be easily transmitted through household contact, especially when hygiene rules are not followed.
Non-infectious forms are not related to infection with bacteria or viruses. Inflammation occurs due to irritation of the mucous membrane or a reaction of the immune system. This group includes:
- allergic conjunctivitis — occurs in response to pollen, dust, animal fur, cosmetics, or other allergens;
- irritant — may develop due to smoke, dust, dry air, chlorinated water, or other eye irritation;
- toxic — is related to irritation of the mucous membrane by chemical substances or some eye preparations.
In non-infectious forms, it is especially important to eliminate the factor that provokes inflammation, since without this the symptoms may recur.
