Corneal Edema in Dogs

Updated February 18, 2017

Researchers estimate that dogs can see less than half the distance that humans are capable of seeing. Like humans, your dog's eyes are susceptible to many eye conditions and diseases, one of which is corneal oedema.

What is a Cornea?

The cornea is the clear, front part of the eye.

What is Corneal Edema?

Oedema occurs when an infection or other eye disease causes the cornea to swell in response, clouding the cornea and distorting vision.


Corneal oedema is typically a response to an infection inside the eye or to eye diseases such as glaucoma, which raises the pressure inside the eye. If you notice changes to the appearance of your dog's eyes, his vision, or the comfort of his eyes, contact your veterinarian to determine the cause of the oedema and if there is treatment for this condition.

How Do Dogs Cope With Vision Loss?

A dog with vision problems, whether minor or extensive, is able to rely on his other senses, such as smell and hearing, to help him function.

Other Eye Problems

Dogs are commonly affected by cataracts, which happens when the lens inside the eye turns cloudy. Dogs also may develop a corneal ulcer, caused from an abrasion.
