​Pink E​ye Virus (Conjunctivitis)

Pink eye is an infection of the transparent membrane (known as the conjunctiva) of your eye, which covers it. When blood vessels become inflamed, your eye becomes red and the engorged vessels are visible on the eye. This can make your eyes extremely red. It might be a little irritating for your child but it is a common disease.

In some cases, the pink eye recovers on its own. However, in a few cases a doctor has to be consulted. Your child will be very restless during this situation and it is highly recommended that he or she doesn’t rub their infected eye as it can increase the redness. 

Pink eyes can be caused by a virus, bacteria or an allergy. It may be due to a specific item, dust or even pollen. If she/he played in a chlorinated pool, the red eye can be a reaction to the chlorine. 

This infection can spread from person to person. Your child can get it by touching an infected person or by using the infected person’s tissue, for instance. It can also be transferred by wearing the infected person’s sunglasses or spectacles. Treatment depends on the specific cause and includes eye drops, ointments, pills, water flushes and comfort care.

Symptoms of Pink Eye (Conjunctivitis)

What are the symptoms of pink eye? Symptoms of pink eye can vary depending on the cause, but common symptoms may include:

  • Redness in the white part of the eye or inner eyelids.
  • Eye itching, burning, or discomfort.
  • Excessive tearing or watery eyes.
  • Discharge from the eye that can be white, yellow, or greenish.
  • Crusting of the eyelashes, especially in the morning.
  • Sensitivity to light (photophobia).
  • Blurred vision.

The severity and specific symptoms can differ based on whether the pink eye is caused by a viral, bacterial, or allergic reaction. It’s essential to identify the cause of pink eye because treatment may vary accordingly. Viral pink eye tends to be more contagious and often goes away on its own within a week or two. Bacterial pink eye may require antibiotic eye drops or ointment prescribed by a healthcare professional. Allergic pink eye is typically treated by avoiding allergens and using antihistamine eye drops.

Causes of Pink Eye:

Causes of pink eye include:

  • Viral Infections: Viruses, such as adenoviruses (most common), herpes simplex virus, or enteroviruses, covid-19 can lead to viral conjunctivitis. It’s highly contagious and can spread through contact with contaminated hands or objects.
  • Bacterial Infections: Bacterial conjunctivitis can result from bacteria like Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. It can also be highly contagious and often occurs alongside a respiratory or ear infection.
  • Allergies: Allergic conjunctivitis can be triggered by allergens like pollen, dust mites, pet dander, or certain chemicals. It’s not contagious and usually affects both eyes.
  • Irritants: Exposure to irritants like smoke, smog, chlorine in swimming pools, or foreign objects can cause irritant conjunctivitis. This type of conjunctivitis is also not contagious.
  • Contact Lenses: Improper use or cleaning of contact lenses can lead to contact lens-related conjunctivitis.
  • Newborns: Newborns can develop conjunctivitis due to blocked tear ducts or exposure to maternal vaginal bacteria during childbirth (neonatal conjunctivitis). It’s different from the more common forms of pink eye.
  • Sexually Transmitted Infections: Certain sexually transmitted infections (STIs) like chlamydia or gonorrhea can cause conjunctivitis if they come into contact with the eye.
  • Chemical Exposure: Exposure to chemicals or irritants like household cleaners, shampoos, or industrial chemicals can lead to chemical conjunctivitis.

Treatment of Pink Eye:

There are several types of conjunctivitis, including viral, bacterial, and allergic conjunctivitis. The treatment for pink eye depends on its underlying cause:

  1. Viral Conjunctivitis:Viral pink eye is usually caused by viruses like adenovirus. It tends to be self-limiting and typically clears up on its own within a week or two.Over-the-counter lubricating eye drops or artificial tears can help alleviate discomfort and keep the eye moist.Cold compresses can reduce swelling and relieve itching.
  2. Bacterial Conjunctivitis:Bacterial pink eye is caused by bacteria such as Staphylococcus or Streptococcus. It may require antibiotic eye drops or ointment prescribed by a healthcare professional.If you suspect bacterial pink eye, it’s important to see a doctor for a proper diagnosis and treatment.
  3. Allergic Conjunctivitis:Allergic pink eye is triggered by allergens like pollen, dust, or pet dander. Avoiding the allergen is the primary treatment.Over-the-counter antihistamine eye drops or oral antihistamines may help alleviate symptoms.Cold compresses can provide relief from itching and redness.
  4. Irritant Conjunctivitis:This form of pink eye is caused by irritants such as smoke, chemicals, or foreign objects. Removing the irritant and rinsing the eye with clean water may be necessary.

Prevention tips for managing pink eye:

  • Wash your hands frequently, especially before touching your eyes, to prevent the spread of infection.
  • Avoid sharing towels, pillows, or eye makeup with others.
  • If you wear contact lenses, switch to glasses until your symptoms improve.
  • Follow your healthcare provider’s instructions and complete the full course of antibiotics if prescribed.
  • If your symptoms worsen or persist, or if you experience severe eye pain, vision changes, or sensitivity to light, seek immediate medical attention.
  • Use a warm compress, such as a washcloth soaked in warm water. Put it on your eye for a few minutes, three to four times a day. This eases the pain and helps break up some of the crust that may form on your eyelashes.
  • Protect your eyes from dirt and other things that irritate them.
