What are the causes, symptoms & treatment of conjunctivitis?


Conjunctivitis: What Are The Causes?

There are several probable reasons, such as:

  • Viruses, including those responsible for the common cold
  • Shampoos, dirt, smoking, and pool chlorine are all factors that cause bacteria to proliferate
  • Adverse effects of ocular drops
  • Allergies are a response to pollen, dust, or smoke 
  • Bacterial conjunctivitis can be brought on by a bacteria – gonorrhea. If you don’t treat it, you risk losing your vision. 
  • Adults who have chlamydia i.e. a common STD  may get conjunctivitis.

If it occurs in a newborn, though, then the baby’s vision could be in danger from an infection.

Conjunctivitis: Symptoms Of It

Depending on what caused the inflammation, symptoms may vary. These are:

  • Greater tears than normal
  • An enlarged conjunctiva
  • Redness in the inner or outer eyelids or the eye white
  • Especially after sleeping, a thick, yellow discharge that crusts across the eyelashes
  • Ocular discharge that is either green or white
  • Lymph nodes that are swollen
  • Scalding eyes
  • Distorted vision

Conjunctivitis: How Is It Diagnosed?

Not all red, itchy, or swollen eyes are viral conjunctivitis, as some people may believe. Seasonal allergies, sty, iritis, chalazion, or blepharitis are additional conditions that may be to blame for your symptoms.

A cotton swab may be used by your eye doctor to collect fluid from your eyelid for laboratory testing in addition to doing an eye exam and questioning you about your symptoms. That will help in figuring out what bacteria or viruses, including those that might cause an STD, may have caused conjunctivitis.

Treatment Depending On What’s The Cause Of Conjunctivitis

  1. Viruses that cause the common cold frequently result in pinkeye. This type of pinkeye typically lasts for 4 to 8 days, and must pass just like a cold must. Do everything you can to stop the spread of the illness because it can be extremely contagious. Virus named Herpes causes pink eye which is quite dangerous
  1. If an irritant, such as dust, pollutants, colloids, etc., caused your pink eye. Give your eyes a five-minute water rinse. Your eyes should start to feel better after 4 hours. Conjunctivitis caused by bleach, acidic, or alkaline chemicals should be treated right away by rinsing your eyes with plenty of water and calling your doctor.
  1. You will take antibiotics if bacteria, particularly those linked to STDs, cause your pink eye. You might need to put on eye drops or ointments 3 to 4 times each day for 5 to 7 days. 
  1. Conjunctivitis caused by allergies should become better after receiving treatment for your allergy. Antihistamines like Benadryl or Hydroxyzine can provide comfort. However, it is suggested to call a doctor before you take meds. Consult a doctor if you think that your pinkeye is being caused by an allergy.

What Can I Do To Treat Conjunctivitis?

In many cases, hygiene is key.

  • Wash your hands frequently with soap and warm water, especially before eating.
  • Your towels, pillowcases, and bed linens should be washed in hot water with detergent.
  • Instead of maintaining your own towels, use paper towels.
  • Avoid touching your inflamed eye with your fingers and keep them away from it.
  • Never share or use contact lenses, eye drops, or eye makeup. Wipe any discharge from your eyes with a fresh cotton ball or paper towel. 
  • If you have used a towel and cotton balls, wash your hands with warm water and soap.
  • Apply a warm compress, such as a warm-water-soaked washcloth. Place it on your eye for a brief length of time three to four times each day.
  • Utilize eye drops just as needed. Use them for no more than a few days unless your eye doctor advises you to. It can make the redness worse.
  • Don’t put a patch over your eye. It can worsen the infection.
  • Keep dirt and other items that might irritate your eyes out of your eyes.
  • If your kid has bacterial or viral pink eyes, keep them home from daycare or school until they are no longer contagious.

How Do I Avoid Pink Eyes?

  • Maintain a clean handshake. If you contact your eye or the region around it, wash your hands well and frequently.
  • Avoid your triggers if allergies are the cause of your pinkeye. Avoid rubbing your eyes, since this could make it worse. Use a cool compress or a cold water spray to cool off your cheeks and eyes. Continue taking your allergy medication.
  • Your lips and nose are other entry points for infections into the body. Do not, even with relatives, share washcloths, bath towels, pillowcases, or handkerchiefs. Use only your own eye drops and cosmetics, especially mascara and eyeliner pencils.
  • Your eyes may occasionally become irritated by the chemicals used to clean contact lenses. If you adjust the way you clean your contacts, you might feel better, but make sure to sanitize them first before putting them back in your eyes.

When To Contact Your Physician

Decide to call if

  • Your eyelids are frequently stuck together in the morning 
  • There is a lot of yellow or green discharge coming from your eye
  • Eye hurts terribly when you gaze at a bright light
  • Pink eye plainly impedes your eyesight
  • You get a severe headache, face pain, shaking chills, or vision loss


f your newborn gets pinkeye, you should contact your doctor right away because it could permanently impair their vision. Your ophthalmologist could instruct you to come in for an immediate appointment. If an adult has mild pink eye, call your primary care physician if you can’t reach your eye doctor. You should see an eye doctor if your symptoms don’t worsen after two weeks and the redness doesn’t go away.
