What Is Corneal Ulcer?

Corneal Ulcer Symptoms

Symptoms may include:

  • Eye pain and redness
  • Excessive watering or discharge
  • Sensitivity to light
  • Blurred or reduced vision
  • A white or grey spot on the cornea

Seek urgent, same-day eye assessment if you develop a painful red eye, light sensitivity or reduced vision—especially if you wear contact lenses. Do not wait for a white spot to appear.

A corneal ulcer is an open sore on the cornea—the clear front surface of the eye. It is often caused by an infection and may develop after an eye injury or in association with contact lens wear or other eye surface problems.

Corneal ulcers can damage the cornea and affect vision. Prompt assessment by an eye doctor is important because treatment delays may lead to scarring or permanent vision loss.

Treatment depends on the cause and severity of the ulcer. An eye doctor may take a small sample from the cornea to identify the infection and guide treatment. Medicated eye drops are often needed frequently, with close follow-up to monitor healing.

Stop wearing contact lenses and use all prescribed medication as directed. Do not start steroid eye drops unless specifically prescribed by your eye doctor. Seek urgent reassessment if pain, redness or vision worsens.
