Glaucoma in Dogs: What You Need to Know

Glaucoma is a serious eye condition that affects dogs, just as it does humans. It is important for dog owners to have a good understanding of glaucoma in order to recognize the signs, seek appropriate veterinary care, and effectively manage the condition. In this section, we will provide you with essential information about glaucoma in dogs.

What is Glaucoma?

Glaucoma is a disease characterized by increased pressure within the eye, known as intraocular pressure (IOP). This elevated pressure can lead to damage to the optic nerve, which is responsible for transmitting visual signals from the eye to the brain. If left untreated, glaucoma can result in vision loss and even blindness.

Primary and Secondary Glaucoma

In dogs, glaucoma can be classified as either primary or secondary. Primary glaucoma occurs spontaneously and is often inherited, resulting from a structural abnormality in the eye that impairs fluid drainage. On the other hand, secondary glaucoma is caused by an underlying condition, such as inflammation, trauma, or tumor, which disrupts the normal flow of fluid within the eye.

Acute and Chronic Glaucoma

Glaucoma can also be categorized as acute or chronic. Acute glaucoma refers to a sudden and severe increase in intraocular pressure, leading to rapid onset of symptoms and requiring immediate medical intervention. Chronic glaucoma, on the other hand, develops gradually over time and may have milder symptoms initially.

Breeds Predisposed to Glaucoma

Certain dog breeds are more prone to developing glaucoma compared to others. For example, breeds such as Cocker Spaniels, Basset Hounds, Siberian Huskies, and Beagles have a higher risk of primary glaucoma. It is important for owners of these breeds to be particularly vigilant in monitoring their dog’s eye health.

Impact on Vision

Glaucoma can cause irreversible damage to the optic nerve, leading to vision impairment or loss. Dogs with glaucoma may experience decreased visual acuity, changes in peripheral vision, and increased sensitivity to light. It is crucial to seek prompt veterinary care to minimize the impact on your dog’s vision and overall well-being.
