Conjunctivitis: Causes, Symptoms, and Treatment

Conjunctivitis, also known as pink eye, is an inflammation or infection of the transparent membrane that lines the inside of your eyelids and covers the white part of your eye. This condition is very common and can be caused by various factors, including viruses, bacteria, allergies, and irritants.

 

Viral: The most common cause of conjunctivitis, often associated with the common cold or flu.

Bacterial: Bacteria can also cause conjunctivitis, usually producing more pus-like discharge.

Allergic: Allergens such as pollen, dust, and pet dander can trigger allergic conjunctivitis.

Irritants: Smoke, chlorine in swimming pools, and contact lenses can irritate the conjunctiva.

 

Redness of the eye: The most common symptom of conjunctivitis.

Itching: Especially in allergic conjunctivitis.

Discharge: Eye discharge can be watery, pus-like, or sticky.

Feeling of a foreign object in the eye

Blurred vision: May occur in severe cases.

Swollen eyelids

 

Treatment for conjunctivitis depends on the cause:

 

Viral conjunctivitis: Usually resolves on its own and does not require specific treatment.

Bacterial conjunctivitis: Can be treated with antibiotic eye drops.

Allergic conjunctivitis: Can be managed with antihistamine eye drops and avoiding allergens.

 

Wash hands frequently: To prevent the spread of infection.
