Just like the skin, dogs’ and cats’ corneas (clear part of the eye) can get scratched or injured.  A corneal ulcer is a scratch or abrasion on the cornea of the dog or cat.  The eye may get scratched from many things.  Just like a scratch on our skin, a scratch (corneal ulcer) in the eye may get infected or worsen.

Q. What does a corneal ulcer in dogs and cats look like?

Corneal ulcers in dogs and cats are uncomfortable and will typically cause your dog or cat to have tearing, squinting or “pus-like” discharge in the affected eye.  Your pet may also be reluctant to let you touch their eye.  The eye may also have redness and swelling of the tissues around the eye.

Q. What could happen with a corneal ulcer in dogs and cats?

Corneal ulcers in dogs and cats may not heal properly or may get infected.  Depending on the type of ulcer and the cause of the corneal abrasion, your pet may need further treatment or care with a veterinary ophthalmologist like Dr. Davis.  If a corneal ulcer in dogs and cats does not heal within a week, it is likely that the corneal ulcer (corneal abrasion, corneal scratch) is more complicated.

Q. How are corneal ulcers in dogs and cats treated?

It is very important to treat corneal ulcers in dogs and cats as soon as possible to help alleviate the irritation and discomfort for your pet.  A full pet eye exam may be needed to look for other eye problems that could have caused the corneal ulcer or infection.  Most corneal ulcers in dogs and cats are treated with medications.  Some corneal ulcers in dogs and cats are deeper or cause more damage to your dog or cat’s eye.  In these cases, a corneal transplant may be needed to repair the area.

Q. What happens if corneal ulcers in dogs and cats are very deep?

Most ulcers are treated with drops or therapy during the pet’s eye examination.  Even if the pet corneal ulcer is deep or if the eye perforates, most dog and cat eyes can be repaired with a corneal transplant or other treatment.  There are many types of surgeries that our veterinary ophthalmologist, Dr. Davis, can do to save your pet’s vision, even with very serious corneal disease.

Q. I think my dog or cat has a corneal ulcer, what should I do?

If you think your dog or cat has a corneal ulcer or other eye condition, you should schedule an appointment at our office for an examination.
