Some cases of viral conjunctivitis go away without treatment. Eye care and hygiene are necessary to avoid other complications.


Conjunctivitis is a very common disease, most commonly associated with upper respiratory tract infections or allergic fever. In children, conjunctivitis is usually caused by infection, while in adults it is usually caused by allergies.


Diagnosis is based on characteristic symptoms:

Red, uncomfortable, itchy, and droopy eyes, but especially painless. If you have eye pain, another eye problem must be thought of.

In most cases of purely conjunctivitis, the obvious signs are bloodshot irises, a lot of green or yellow discharge, causing the eyelids to stick together when the patient first wakes up. . If it is conjunctivitis due to infection, there will be white pus in the eye. If it is allergic conjunctivitis, use clearer eyes but swollen eyelids.

Look for signs of vasodilation in the conjunctiva.

Hard edema of the conjunctiva below the eyelids.

For the new born, it is necessary to have an eye secretion test to determine the exact type of bacteria causing the disease.


Some cases of viral conjunctivitis go away without treatment. Eye care and hygiene is necessary to avoid other complications.

In case of a confirmed diagnosis or suspicion of infection, an eye ointment with an antibiotic such as chloramphenicol is given 3 times a day, or an eye drop 4 times a day, continuously for about 2-4 days.

Rinse eyes with warm water, use a soft gauze soaked in water regularly to prevent the eye from closing on the eyelids.

If the diagnosis is certain that there is no infection, that is, allergic conjunctivitis, an antihistamine eye drop may be indicated. You can also use corticosteroid eye drops. Use extreme caution, as these drugs are very effective in allergic conjunctivitis, but if there is an infection, they can make the infection worse.

Treat diseases that may be the cause of conjunctivitides, such as allergic fever or upper respiratory infection.

Conjunctivitis is an infectious disease, so it is important to instruct patients on precautions such as not sharing handkerchiefs, face towels ... and regular eye hygiene. However, for children at the start of treatment, the possibility of infection no longer exists, so it is not necessary to force the child to drop out of school.
