Glaucoma Can Affect Dogs Too

Glaucoma is a disease that causes an increased pressure inside of the eye. There are many causes of glaucoma including a heritable condition in certain breeds. As the eye pressure increases, blindness results from the progressive death of the retinal cells. Early detection with tonometry and treatment of the underlying causes may preserve the dog’s sight.
Signs of acute (sudden onset) glaucoma can include pain in the eyes, rubbing at the eye, increased blinking and tearing. There may be an increased redness, a discharge from the eye, a bluish discoloration of the cornea, a dilated pupil or sudden vision loss.glaucoma
Chronic glaucoma can include any or all of the fore-mentioned signs plus an enlargement of the globe, cataract, lens subluxation and small white lines on the cornea resulting in breaks in the cornea from the increased pressure.
Diagnosis is made by the veterinarian by examination and measurement of the internal pressure of the eye with tonometry. Treatment will depend on the cause and the extent of the glaucoma. Some can be treated with medications while some may require surgery. In severe, chronic cases, removal of the globe will relieve the pain and will make the dog more comfortable.

Ask your veterinarian if your dog is among the breeds most susceptible to glaucoma and include an eye exam with your dog’s annual check-ups. Cats can also be affected by glaucoma
