What Is a Corneal Ulcer?
A corneal ulcer is an open sore on the cornea. The cornea covers the iris and the round pupil, much like a watch crystal covers the face of a watch. A corneal ulcer usually results from an eye infection, but severe dry eye or other eye disorders can cause it.
Corneal ulcer symptoms
Symptoms of corneal ulcers include:
- redness of the eye
- severe pain and soreness of the eye
- the feeling of having something in your eye
- 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
See your ophthalmologist immediately if you think you have a corneal ulcer or have any eye symptoms that concern you. Corneal ulcers can badly and permanently damage your vision and even cause blindness if they are not treated.
