Disorder - GlaucomaOrgan Systems Involved
Glaucoma cannot be defined as a single disease. It is in fact many disorders in
which the pressure of the fluid within the eye is too high to allow normal functioning of the nerves within the eye.
One or both eyes may be affected, but presenting signs of glaucoma will vary according to the stage of the disease when the dog is first examined. Glaucoma is very painful and affected dogs will rub the eye(s) with the paws or on carpets and furniture. Many dogs are sensitive to bright light and will therefore hide under the furniture or in a dark corner of the room. One of the main causes of pain is due to an increase in the size of the eye, which is due to high pressure of fluid within the eye and stretching of tissues within the eye. The blood vessels within the eye are also affected, causing degeneration of the optic nerve, the nerve that carries messages from the eye to the brain. This is thought to be the main cause of eventual loss of vision.
