A corneal ulcer, also known as ulcerative keratitis, is a cornea lesion usually due to infection with bacteria, viruses, or fungi. The cornea is the clear, dome-shaped surface that covers the front of the eye. Other causes of corneal ulcers include injury (for example, from a sharp object), contact lens use, and other diseases that affect the eyes. Symptoms of a corneal ulcer include pain, redness, swelling, discharge from the eye, and blurred vision.
