Glaucoma is a severe eye disease.  Glaucoma is abnormally high pressure in the eye. Inside the normal eye there is constant production and drainage of a watery fluid called aqueous humor. When there is a problem with the drainage of the fluid, the pressure within the eye can increase. High pressure causes damage to the optic nerve, which, in turn, causes vision loss.

We now have one of the most accurate instruments to test for glaucoma, a Tonopet-Vet.  Many breeds of dogs and cats may have more of a chance for glaucoma and blindness due to heredity.  Screening for glaucoma is highly recommended!
