What is conjunctivitis?
Conjunctivitis, or pink eye, is inflammation of your conjunctiva. The conjunctiva is a thin tissue that covers the front of your eye and the back of your eyelid. The conjunctiva helps protect your eye and keep it moist.
What causes conjunctivitis?
The most common cause of conjunctivitis is infection with bacteria or a virus. Allergies or exposure to a chemical may also cause conjunctivitis. Conjunctivitis is easily spread from person to person.
What are the signs and symptoms of conjunctivitis?
You may have symptoms in one or both eyes. You may also have other general symptoms, including a sore throat, runny nose, or fever. You may have any of the following:
- Redness in the whites of your eye
- Itching in or around your eye
- Feeling like there is something in your eye
- Watery or thick, sticky discharge
- Crusty eyelids when you wake up in the morning
- Burning, stinging, or swelling in your eye
- Pain when you see bright light
How is conjunctivitis diagnosed?
Your healthcare provider will ask about your symptoms and medical history. Tell the provider if you have been around anyone who is sick or has pink eye. Your provider may ask if you have allergies or wear contact lenses. You may need any of the following:
- A visual acuity test checks your vision in both eyes. You will be asked to read letters and numbers from a chart.
- An eye exam may help your provider find out what is causing your conjunctivitis. Your provider will look at your eyes, eyelids, eyelashes, and the skin around your eyes. You will be asked to look in different directions. Your provider may gently press on your eye or eyelid to see if there is drainage. Your provider may gently swab your conjunctiva with a cotton swab and send it to the lab for tests.
- A slit-lamp exam may show a cut, scratch, or other damage to your cornea. This exam may also show a foreign object in your eye. A microscope with a bright light is used to check every part of your eye. A dye called fluorescein may be used.
How is conjunctivitis treated?
Your conjunctivitis may go away on its own. Treatment depends on what is causing your conjunctivitis. You may need any of the following:
- Allergy medicine helps decrease itchy, red, swollen eyes caused by allergies. It may be given as a pill, eye drops, or nasal spray.
- Antibiotics may be needed if your conjunctivitis is caused by bacteria. This medicine may be given as a pill, eye drops, or eye ointment.
