How is a corneal ulcer diagnosed?

Your eye care provider will:

• Perform an examination with a slit lamp microscope. The slit lamp focuses a narrow “slit” of light onto the eye. A slit lamp exam is a normal part of an eye exam.
• Your provider may apply a fluorescein dye to your eye. This yellow dye highlights any damage to your cornea.
• Take a sample of the infected tissue. The results will show the type of infection and guide medication choice for treatment.
