Corneal Eye Problems

The following are common eye problems that occur on the cornea (outer layer) of the cats eye:

  • Corneal ulcers: A scratch or abrasion on the cornea of the dog or cat.

  • Trauma to the Cornea: Injuries to the cornea can be sharp or blunt.  Sharp trauma often causes corneal abrasions or lacerations.  These are an emergency and require immediate veterinary attention.  Blunt trauma can cause inflammation in the front chamber of the eye leading to cloudiness and inflammation.

  • Ruptured cornea: This is when the cornea is cut and starts to release the inner contents of the eye.

Herpes Keratitis and Conjunctivitis in Cats
