Our canine companions rely heavily on sight to navigate the world, play fetch, and illuminate us with their soulful puppy eyes. So the thought of your dog losing its sight can be heartbreaking. Although in some cases blindness is a natural part of aging, several other factors can contribute to vision loss in dogs.
According to Wag!, many challenges and scenarios are not threatening if your canine companion has sight, but can be dangerous if they are visually impaired. Here we explore some of the most common causes of blindness in dogs.
Causes of blindness in dogs
- Cataract: As in humans, cataracts are the leading cause of blindness in dogs. This occurs when the lens of the eye becomes cloudy and blocks light from reaching the retina. Cataracts can develop with age, be caused by diabetes or trauma, or be inherited in certain breeds.
- Glaucoma: This painful condition is caused by increased pressure within the eye, damaging the optic nerve and leading to vision loss. Symptoms include strabismus, bloodshot eyes, and excessive tearing. Early diagnosis and treatment are important to prevent permanent vision loss.
- Sudden acquired retinal degeneration (SARD): This is a rapid and devastating condition that can leave your dog completely blind within days or weeks. The exact cause is unknown, but it is common in middle-aged female dogs of certain breeds.
- Diabetes mellitus: Diabetes can seriously affect your dog's health, including his vision. Diabetic cataracts progress rapidly and can lead to blindness if not treated effectively.
- Corneal disease: Diseases of the cornea (the transparent part at the front of the eye) can cause scarring and clouding, which can impair vision. This can be caused by an infection, scratch, or dry eyes.
- Inherited conditions: Certain breeds of dogs are more prone to inherited eye diseases that can lead to blindness. These include progressive retinal atrophy (PRA), which affects the light-sensitive cells of the retina, and keratoconjunctivitis sicca (KCS), also known as dry eye.
- trauma: Severe eye injuries caused by accidents, fights, or foreign objects can cause permanent vision loss. Prompt veterinary attention is essential to minimize damage and preserve vision.
Signs of blindness in dogs:
- bump into objects or furniture
- Hesitation on stairs or in unfamiliar environments
- Excessive sniffing and following walls
- Pupils are dilated and do not respond to light
- Eyes become cloudy or discolored
If you suspect that your dog may be losing vision, it is important to consult your veterinarian for a thorough examination. Early diagnosis and treatment can slow the progression of certain symptoms and even restore vision.
