Causes of Pink Eye in Babies
Pink eye in babies can be caused by a variety of factors, including:
- Bacteria: Bacterial conjunctivitis is the most common type of pink eye in babies. It is caused by bacteria such as Staphylococcus aureus or Streptococcus pneumoniae.
- Viruses: Viral conjunctivitis is less common than bacterial conjunctivitis. It is caused by viruses such as adenovirus or herpes simplex virus.
- Allergies: Allergic conjunctivitis is caused by an allergic reaction to an allergen, such as pollen, dust, or pet dander.
Diagnosis of Pink Eye in Babies
Pink eye in babies is usually diagnosed based on a physical examination of the eye. Your doctor will look for signs of redness, swelling, discharge, and crusting. They may also ask about your baby’s symptoms and medical history.
In some cases, your doctor may order tests to confirm the diagnosis of pink eye. These tests may include:
- Eye culture: A sample of discharge from the eye is taken and sent to a laboratory to grow bacteria.
- Viral antigen test: A sample of discharge from the eye is tested for the presence of viral antigens.
- Allergy skin test: A small amount of allergen is injected into the skin to see if it causes a reaction.
Treatment of Pink Eye in Babies
The treatment for pink eye in babies depends on the cause of the infection.
- Bacterial conjunctivitis: Bacterial conjunctivitis is treated with antibiotic eye drops or ointment.
- Viral conjunctivitis: Viral conjunctivitis is usually treated with supportive care, such as cool compresses and artificial tears. In some cases, antiviral eye drops may be prescribed.
- Allergic conjunctivitis: Allergic conjunctivitis is treated with antihistamine eye drops or ointment.
