CONJUNCTIVITIS

Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin, transparent layer of tissue that covers the inner surface of the eyelid and the white part of the eyeball.

Viral Conjunctivitis 

Often caused by viruses that cause the common cold, such as adenovirus. It's highly contagious and can spread through respiratory droplets or by touching contaminated surfaces.

Bacterial Conjunctivitis 

Caused by bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. It can result from an eye infection or as a secondary infection due to a cold or respiratory infection.

Allergic Conjunctivitis

Triggered by allergens such as pollen, dust mites, pet dander, or certain chemicals. It's not contagious.

Chemical Conjunctivitis: Caused by exposure to irritants like chlorine in swimming pools, air pollution, or harsh chemicals. It's not contagious.

Symptoms

Redness of the eye(s)

Watery or mucous discharge from the eye(s)

Itching or burning sensation in the eye(s)

Grittiness or foreign body sensation

Swelling of the eyelids

Sensitivity to light (photophobia)

Diagnosis

Diagnosis is typically based on symptoms and a physical examination of the eye(s) by a healthcare professional.

In some cases, a swab of the conjunctiva may be taken to determine the cause, especially if bacterial conjunctivitis is suspected.

Prevention

Practice good hygiene, including regular handwashing, especially during cold and flu seasons.

Avoid touching or rubbing your eyes, especially if you've been in contact with someone who has conjunctivitis.

Avoid sharing towels, pillows, or eye makeup with others during an outbreak of conjunctivitis.

If you have allergic conjunctivitis, try to minimize exposure to allergens that trigger your symptoms.
