What is Bacterial Keratitis?

Bacterial keratitis is an infection of the cornea (the clear dome covering the colored part of the eye) that is caused by bacteria. It can affect contact lens wearers, and also sometimes people who do not wear contact lenses. Types of bacteria that commonly cause bacterial keratitis include: Pseudomonas aeruginosa.

  • Eye redness.
  • Eye pain.
  • Blurred vision.
  • Decreased vision.
  • Sensitivity to light, called photophobia.
  • A feeling that something is in your eye.
  • Excess tears or other discharge from your eye.
  • Difficulty opening your eyelid because of pain or irritation.
  • Chronic corneal inflammation and scarring.
  • Chronic or recurrent viral infections of your cornea.
  • Open sores on your cornea, called corneal ulcers.
  • Temporary or permanent reduction in your vision.
  • Blindness.

The most common species causing bacterial keratitis include Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Pseudomonas aeuruginosa, and species of the Enterobacteriaceae family.

If you wear contact lenses, proper use, cleaning and disinfecting can help prevent keratitis. Follow these tips: Choose daily wear contacts and take them out before going to sleep. Wash, rinse and dry your hands thoroughly before handling your contacts.

  • Contact lenses. Wearing contact lenses — especially sleeping in the lenses —increases your risk of both infectious and noninfectious keratitis.
  • Reduced immunity. If your immune system is weakened due to disease or medications, you're at higher risk of developing keratitis.
  • Corticosteroids.
  • Eye injury.
