Conjunctivitis in Children

May 31, 2018

Conjunctivitis is an inflammation of the conjunctiva of the eye. The conjunctiva is the membrane that lines the inside of the eyelids and covers the eyeball. Conjunctivitis is also known as “pink eye” because the eye looks pink or red.

In children, the condition is often grouped into either newborn conjunctivitis or childhood conjunctivitis. There are different causes and treatments for each group.

Types of newborn conjunctivitis include:

  • Chemical conjunctivitis. This is a rare condition caused by irritation from eye drops that are given to newborn babies to help prevent a bacterial infection. The eyes are often red and inflamed, starting a few hours after the drops have been put in the eye. The symptoms last about 2 to 4 days. This type of conjunctivitis often doesn’t need treatment.
  • Gonococcal conjunctivitis. This is caused by bacteria called N. gonorrhea. A newborn baby can pick up this type of bacteria during vaginal birth from an infected mother. This severe type of conjunctivitis may be prevented with the use of eye drops in newborns at birth. The condition causes eyes that are very red, with swelling and thick fluid leaking from the eyelids. Symptoms usually start about 2 to 5 days after birth. Treatment often includes IV antibiotics.
  • Inclusion conjunctivitis. This is the most common type of bacterial infection. It is caused by an infection with Chlamydia trachomatis. The symptoms include red eyes, swollen eyelids, and fluid leaking from the eyelids. Symptoms usually start 5 to 14 days after birth. Treatment often includes antibiotics taken by mouth (oral).
  • Infection from other bacteria. After the first week of life, other bacteria may be the cause of conjunctivitis in a newborn. The eyes may be red and swollen with some drainage. Treatment depends on the type of bacteria that have caused the infection. Treatment often will include antibiotic drops or ointments to the eye, warm compresses to the eye, and correct hygiene when touching the infected eyes.

Childhood conjunctivitis is a swelling of the conjunctiva and may also include an infection. It is a very common problem in children. Large outbreaks of conjunctivitis are often seen in daycare settings or schools. The most common causes of childhood conjunctivitis are:

  • Bacteria
  • Viruses, including the herpes virus
  • Allergies

If the condition is caused by an infection, it’s important to know that the infection can spread from one eye to the other by touching the affected eye or fluid from the eye. The infection can also spread to other people. Fluid from the eye is still contagious for 24 to 48 hours after starting treatment.

There are many different causes of conjunctivitis. The most common causes are:

  • Bacteria such as:
    • Staphylococcus aureus
    • Haemophilus influenza
    • Streptococcus pneumoniae
    • Neisseria gonorrhea
    • Chlamydia trachomatis
  • Viruses such as:
    • Adenoviruses
    • Herpes virus
  • Chemicals in newborn eye drops
  • Allergies

A child who has had contact with any of the below are at risk for the condition:

  • Staphylococcus aureus
  • Haemophilus influenza
  • Streptococcus pneumoniae
  • Neisseria gonorrhea
  • Chlamydia trachomatis
  • Adenoviruses
  • Herpes virus
  • Chemicals in newborn eye drops

Symptoms can occur a bit differently in each child. They can include:

  • Itchy, irritated eyes
  • Swelling of the eyelids
  • Redness of the conjunctiva
  • Mild pain when the child looks at a light
  • Burning in the eyes
  • Eyelids that are stuck together in the morning
  • Clear, thin fluid leaking from the eyes, most often from a virus or allergies
  • Sneezing and runny nose, most often from allergies
  • Stringy discharge from the eyes, most often from allergies
  • Thick, green drainage, most often from a bacterial infection
  • Ear infection, most often from a bacterial infection
  • Lesion on eyelids with a crusty appearance, most often from a herpes infection

The symptoms of conjunctivitis can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

The healthcare provider will ask about your child’s symptoms and health history. He or she may also ask about your family’s health history. He or she will give your child a physical exam. In some cases, a sample of the fluid leaking from the eye may be tested to help confirm the cause of the infection.

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on the cause of the condition, for example:

  • Bacterial infection. This may be treated with antibiotic eye drops.
  • Viral infection. Viral conjunctivitis usually doesn’t need treatment. In some cases, antibiotic eye drops may be used to help prevent a secondary infection.
  • Allergic reaction. The allergies may be treated oral medicines or eye drops.
  • Herpes infection. Your child may need to see an eye doctor (ophthalmologist). Your child may be treated with both oral medicine and eye drops. 

If the condition is caused by an infection, it’s important to know that the infection can spread from one eye to the other by touching the affected eye or fluid from the eye. The infection can also spread to other people. Fluid from the eye is still contagious for 24 to 48 hours after starting treatment.

To help prevent spread of the infection, wash your hands often when caring for your child. Make sure your child doesn’t touch his or her eyes. Have your child wash his or her hands often. 

Conjunctivitis caused by herpes is a more serious infection. If untreated, it may lead to scarring of the eye and vision loss.

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.
  • Before your visit, write down questions you want answered.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
  • Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
  • Ask if your child’s condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
  • Know what to expect if your child does not take the medicine or have the test or procedure.
  • If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
  • Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
