Introduction
Glaucoma is a condition that occurs when fluid begins to build up within the eye, and as a result pressure in the eye increases. When this progressive condition occurs in dogs it may occur either in one or both eyes, and immediate treatment is necessary to prevent permanent eye damage, blindness, and painful symptoms of the disease.
Causes of Glaucoma in Dogs
There are different types of glaucoma that can occur in dogs, and within these types the glaucoma is categorized as primary or secondary depending on the cause of the condition. Primary glaucoma is a condition that exists on its own. Dogs develop primary glaucoma either due to age, hereditary issues, or for unknown reasons. Secondary glaucoma occurs as a result of a condition such as trauma to the eye, eye conditions such as cataracts, or even cancer.
Symptoms of Glaucoma
The first signs of glaucoma begin within the dog’s eyes. Pet owners may notice that the dog’s pupils seem more dilated than usual, and the pupils may be slow to contract in sudden light. The eyes may also appear irritated and tearful. The condition may also cause behavioral changes due to pain and their pet can become depressed or irritable.
Treating Glaucoma in Dogs
Treating canine glaucoma depends on what is causing the condition and the stage of the glaucoma. In some cases, eye medications which help to decrease the amount of fluid in the eyes are enough to control the condition. In other cases surgery is needed to reduce the eye pressure.
Outlook for Dogs with Glaucoma
Glaucoma is not a life threatening condition, but it can affect a dog’s quality of life due to the pain the disease causes. The outlook of glaucoma, and how much of the dog’s vision is affected, depends on the progression of the condition, how early treatment began, and if the glaucoma responds well to the treatment.
