Dog Eye Problems

Dog eye problems include corneal ulcers. This image shows a
large corneal ulcer in a Cocker Spaniel, which has been stained with a
green dye so it is easily seen.
All dog eye problems should receive immediate attention. Left
unattended, they can evolve into more serious issues and may ultimately
result in loss of sight. The most common eye problems include:
- Blindness in Dogs:
SARDS, or Sudden Acquired Retinal Degeneration Syndrome, is a condition where a dog goes blind without advance warning.
- Canine cataracts:
A cataract is opaque, meaning light cannot pass through it. A dog with a cataract is not able to see
through the cataract. If the entire lens is involved, the eye will be blind.
- Nuclear sclerosis:
This occurs as a dog ages. The eye looks cloudy but the dog can still see through the milky lens.
- Canine entropion (ingrowing eyelids):
This is a condition where the eyelid turns inward and the eyelashes rub
against the eye and
irritate it. It is at the very least annoying to the dog, and at most,
very painful. This dog eye health issue can be corrected with surgery.
- Cherry eye:
This condition occurs when the tear gland of the third eye prolapses or
moves out of place. Surgery is needed to remedy the problem.
- Dog eye infection: This may occur as part of a
bacterial or viral infection. It may also occur when the outer part of
the eye, called the cornea, is scratched.
- Canine corneal ulcers: These are often caused by injuries to the cornea such as a cat scratch or dirt or other debris rubbing
against the cornea. This condition is serious and should be under the care of a veterinarian.
- Dog eye injuries: Injuries may be caused by
scratching the cornea, bumping the eye or when a foreign object (dirt,
sand, wood splinters)enters the eye.
Signs that your dog may have one of these eye health issues
include blinking, tearing, redness, swelling around the eye and pus in
As is the case with all dog health issues, it's important to
"know your dog." You live with your dog and you should be aware of any
differences in his behavior or in signs that may indicate illness. In
addition to the above, it is also important to note if your dog is
acting differently—for instance, he's depressed and won't leave his
bed—there could be any number of health issues behind his
uncharacteristic actions, including dog eye problems.

veterinarian if your canine friend "is not himself."
