While Glaucoma is an extremely serious illness, it doesn't usually
happen in dogs too much. Most of the time blindness in dogs happens
from an accident, although there are those moments when Glaucoma
happens due to genetic issues.
When genetics are the cause, this is
called primary Glaucoma. There are some breeds that are more
genetically inclined to catch Glaucoma, but a dog can get it because of
eye disease, cataracts, cancer, or even eye inflammation. When it is
caused by any of these issues it will be considered secondary Glaucoma.
If dogs get Glaucoma, they can go blind quite rapidly. Care should be
given if you notice any of these issues.
Most of the time a dog
will get Glaucoma in just one eye. The pressure comes from the aqueous
humor fluid that is being built up constantly in the front part of the
eye. When this happens the dog will eventually lose sight in that eye,
but will adjust to seeing with the good eye. Because of this, it is
difficult for the owner to realize the dog is having sight issues as
they are still getting around quite well. This will also cause the dog
pain, which they have no way of telling you about.
When a dog
has been diagnosed with Glaucoma it becomes much harder to treat than
if contracted by a human. Humans will take eye drops to help relieve
the pressure whereas dogs have a hard time squeezing the bottle, so you
have to do it for them. If you have never tried to give a dog eye drops
before, it can be quite a difficult feat. Because of this, surgery will
more than likely be required to release the pressure. Unfortunately, up
to one third of dogs will have to have more than one surgery for their
Glaucoma issues.
While Glaucoma in dogs is rarely detected
before it's too late, there are ways of catching it before it's too
serious. If you notice your dog favoring one eye, or see it constantly
watering, you should check with your vet. If your vet catches the
Glaucoma before it gets too serious, there is a good chance that your
dog will only require one surgery. While your dog has no way of telling
you that their eyes are bothering them, you have to be on your toes and
check from time to time on your own.
