Corneal Ulcer

What is a corneal ulcer?

Be Eye Wise and learn that a corneal ulcer is an open sore on the surface of your cornea. In many cases, this sore is caused by severe dry eye, but can also be triggered by other eye conditions.

Symptoms of a corneal ulcer can be:

  • Redness of the eye.
  • Severe pain and soreness of the eye.
  • The feeling of having something in your eye.
  • Tearing.
  • Pus or other discharge.
  • Blurred vision.
  • Sensitivity to light.
  • Swelling of the eyelids.
  • A white spot on your cornea that you may or may not be able to see when looking in the mirror.

Causes of a corneal ulcer can be:

  • Bacterial infections, especially common for people who use extended wear contacts.        
  • Viral infections.
  • Fungal infections.
  • Parasitic (acanthamoeba) infections.
  • Abrasions or burns to the cornea caused by injury to the eye.
  • Dry eye.
  • Bell’s palsy and other eyelid disorders that prevent proper eyelid function.

Treating a corneal ulcer:

Antibiotics, anti-fungal and anti-viral eye drops are all commonly used to treat corneal ulcers. Prescription injections and tablets are also possibilities. If the corneal ulcer cannot be treated with one of these methods, a surgical solution involving a corneal transplant is advised.
