Introduction
Symptoms of glaucoma are extremely vague, and many pet owners do not realize that their dog is suffering from the condition until it is at an advanced stage. However, subtle changes to the dog’s eyes can provide an early warning that glaucoma is present. This is why it is important for pet owners to ensure that their dogs have regular physical exams, and that they pay close attention to any change in their dog’s eye health.
Symptoms of Glaucoma in Dogs
Glaucoma symptoms may appear in one, or both, of the dog’s eyes. In many cases the condition appears in one eye and gradually spreads to the other eye. The beginning symptoms of glaucoma usually involve changes to the pupil. The pupil of the eye may appear slightly larger, and it may not contract quickly when exposed to light. Pet owners may also notice other changes to their dog’s eyes such as redness, a cloudy appearance to the eye, irritation, and excess tearing. In advance stages of glaucoma the affected eye(s) will begin to bulge and appear larger than normal.
If the dog’s vision has been affected by the disease, pet owners may notice changes to the dog’s vision. The dog may stumble over objects in its path, bark more often at people, or bump into the corners of walls and doorways.
Dogs may also exhibit behavioral changes due to glaucoma that are caused by pain. The dog may seem lethargic, depressed, irritated, or may eat less than normal. Pawing at the eyes may also occur as the dog attempts to alleviate the pain. In some cases sensitivity to light and squinting symptoms may also appear.
