Bacterial Pink Eye Versus Viral Pink Eye

Overview

Bacterial pink eye, also known as bacterial conjunctivitis, is an infection of the eye caused by bacteria. It can produce symptoms such as a thicker discharge, pain, and swelling. Bacterial conjunctivitis can be told apart from viral conjunctivitis by factors such as recent contact with a person who had a viral illness or a history of viral illness. While both types of conjunctivitis can improve without medical treatment, bacterial pink eye may require antibiotic eye drops in some cases. It's important to note that certain rare forms of bacterial conjunctivitis can progress rapidly and need urgent treatment.

On the other hand, viral pink eye, also known as viral conjunctivitis, is caused by a virus. It can spread to the eyes from the nose or through contact with respiratory droplets from an infected person who sneezes or coughs. Viral pink eye shares similar symptoms with bacterial pink eye, including a pink or red color in the white of the eyes, tearing, itching or scratchy feeling in the eye, swelling, burning or irritation, crusting of the eyelids or lashes (especially in the morning), and discharge from the eye.

  • Similarities between bacterial pink eye versus viral pink eye:
  • Both types of pink eye can cause a pink or red color in the white of the eyes.
  • They may both result in tearing and an itchy or scratchy feeling in the eyes.
  • Swelling, burning or irritation of the eyes can occur with both bacterial and viral pink eye.
  • Crusting of the eyelids or lashes is common in both types, especially in the morning.
  • Discharge from the eyes is another shared symptom.
  • Differences between bacterial pink eye versus viral pink eye:
  • Bacterial pink eye tends to produce a thicker discharge compared to viral pink eye.
  • Pain and swelling are more commonly associated with bacterial conjunctivitis.
  • Recent contact with a person who had a viral illness is often seen in cases of viral pink eye.
  • Antibiotic eye drops may be needed for bacterial conjunctivitis but not for viral conjunctivitis.
  • Some rare forms of bacterial conjunctivitis may progress rapidly and require urgent treatment.

Remember that it's always important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment. They will be able to determine whether you have bacterial or viral pink eye based on your symptoms and medical history.
