Glaucoma

The pressure in the anterior eye chamber increases which causes the lens to become clouded. The disease ends in blindness. Often both eyes are affected. Some types of glaucoma are considered to be hereditary. Symptoms include redness of the sclera, blue discoloration of the cornea, enlarged pupil, tears, sensitivity to light or even an enlarged eye. The dog will most likely lose the eye, despite treatment.

Primary glaucoma is often hereditary, with a recessive or polygenous inheritance. About 10-20% of the dogs are genetically affected, but only half percent actually develops glaucoma.
