Why Does Corneal Ulcer so Dangerous for Cat?


Corneal ulcer may occur in cats of all breeds and at any age. In young individuals, it may be the result of a trauma, and in adults, a complication of the inflammatory process caused by a viral infection. It is impossible to independently determine the depth and size of the ulcer by eye, therefore, when characteristic symptoms appear, it is recommended not to delay and visit ophthalmologist, as there is a risk of partial or complete loss of vision on the damaged organ.

Why Does It Appear?

In the most of scenarios, corneal ulcer in cats appears due to the following factors:

  1. Trauma. Obtained after a fight or game with other animals. Kittens often injure themselves by playing with their paws and claws on their own. Masters can also injure the cornea during walking through tall grass.
  2. Foreign object. Specks, glass fragments, plant seeds can get under the eyelid. Spikes from weeds and other sharp objects can stick into the conjunctiva. During each blink, the cornea will be irritated and injured. If the splinter is not removed in time, a large ulcer may be formed.
  3. Double row of eyelashes. May be found hardly ever, but also lead to the formation of a deep corneal ulcer in cat. It usually manifests itself at an early age.
  4. Protrusion of the third eyelid. It happens congenital or acquired (after a viral infection). The eyelid irritates the cornea, thereby injuring it. If the process is begun, a deep ulcer may be formed.

It is necessary to understand that corneal ulcer can have infectious and non-infectious origin. This is very important, because the treatment regimens for each case are completely in different way.

Characteristic Symptoms

  1. restless behavior;
  2. swollen eyelids;
  3. redness of conjunctiva;
  4. lacrimation
  5. sour eyes;
  6. crusts on the eyelids;
  7. sticky eyelashes.

If there are blurred eyes, the pet partially or completely does not open the affected organ of vision, then this condition requires immediate medical attention.


For diagnosis, in addition to external determination, a procedure for staining the cornea with fluoresce-in is mandatory. This is a special solution that is applied to the affected organ. Using this procedure, even the smallest cracks and erosion present on the cornea can be detected.

In difficult cases, ophthalmoscopy is used, which allows vets to assess the condition of the retina, optic nerve and fundus vessels. It is usually used after falls from a height, trauma from claws or tree branches.
