Understanding Cataracts in Dogs

Cataracts in dogs are a common eye condition that affects the lens of the eye. The lens is responsible for focusing light onto the retina, which allows your dog to see clearly. When cataracts develop, the lens becomes cloudy or opaque, which can obstruct light and interfere with your dog’s vision.

• Cataracts can develop in one or both eyes.
• They can occur at any age, but are more common in older dogs.
• Cataracts are a leading cause of blindness in dogs.

Causes of Cataracts in Dogs

Cataracts in dogs can be caused by a variety of factors, including:

• Age: As dogs age, the proteins in the lens can start to clump together, forming a cloudy film that can obscure vision. This is a common cause of cataracts in older dogs.
• Genetics: Some dog breeds are predisposed to developing cataracts. These breeds may have inherited genes that make them more susceptible to this condition.
• Diabetes: Diabetes can cause cataracts in dogs, and often leads to rapid growth of the cataracts, covering the entire lens.
• Eye Trauma: An injury to the eye, such as a scratch, can also lead to the formation of cataracts.
• Inflammation: Inflammation within the eye can lead to cataract formation.

Symptoms of Cataracts in Dogs

The symptoms of cataracts in dogs can vary depending on the severity of the condition. In the early stages, your dog may not show any noticeable symptoms. As the cataracts grow, you may notice:

• Cloudy or bluish-gray appearance to the eye
• Difficulty seeing in low light
• Bumping into objects
• Squinting
• Sensitivity to light

Diagnosing Cataracts in Dogs

Your veterinarian can diagnose cataracts in dogs by examining the eyes using a slit lamp, which is a special microscope that provides a magnified view of the eye.

Your veterinarian may also perform blood tests to check for underlying conditions that could be causing the cataracts.

Treating Cataracts in Dogs

There is no way to reverse cataracts once they have formed. However, there are treatment options that can help to improve your dog’s vision.

• Surgery: Cataract surgery is the most common treatment for cataracts in dogs. This surgery involves removing the cloudy lens and replacing it with an artificial lens. Surgery is the only option to improve dog vision once cataracts are formed.
• Medications: Some medications can be used to help manage the symptoms of cataracts and prevent further vision loss. These medications may be used to reduce inflammation or slow the growth of the cataracts. These medications cannot reverse the cataracts.

Preventing Cataracts in Dogs

While you cannot always prevent cataracts in dogs, there are some things you can do to reduce the risk of your dog developing them:

• Regular Eye Exams: Have your dog’s eyes checked by a veterinarian annually, so any dog eye problems, including cataracts, can be diagnosed early.
• Manage Diabetes: If your dog has diabetes, it is important to work with your veterinarian to manage the condition carefully, as diabetes can contribute to the formation of cataracts.
• Protect Your Dog's Eyes: Protect your dog’s eyes from injury, especially during playtime, and make sure your dog avoids potentially toxic substances.
• Consider Genetics: If you are considering getting a dog, research the breed and see if they are prone to developing cataracts. The dog's parents’ medical history is also helpful information.

Living With Cataracts in Dogs

If your dog has cataracts, it’s important to make some adjustments to their environment to help them navigate and feel safe. These adjustments will help your dog live a happy and fulfilling life despite their vision loss.

• Keep Your Dog Safe: Keep your dog on a leash when you’re walking them, or in a fenced yard.
• Provide Familiar Surroundings: Avoid moving furniture around.
• Provide Extra Attention: Give your dog lots of affection and comfort, as they may be feeling anxious or confused.
• Work with Your Veterinarian: Your veterinarian can offer advice on how to best manage your dog’s condition.

Dog Eye Surgery

Cataract surgery in dogs is a common procedure that can help to restore vision. While cataract surgery can be effective, it is important to understand the risks and potential complications involved. Some dogs might need to have a second procedure, and in rare cases, the eye may need to be removed.

• The procedure is performed under general anesthesia.
• The cloudy lens is removed and replaced with an artificial lens.
• Recovery from cataract surgery typically takes a few weeks.
• Your veterinarian will provide you with instructions on how to care for your dog after surgery, and might give you eye drops to apply several times a day.

Cost of Dog Eye Surgery

The cost of cataract surgery for dogs can vary depending on the veterinarian, the complexity of the procedure, and the dog's overall health. The cost of pre-operative tests, anesthesia, surgery, and follow-up care may range from $500-$4,500 per eye.

Maintaining Dog Eye Health

Cataracts in dogs are a serious condition, but with proper management, they can be treated effectively. Regular eye exams are essential for early detection and management. Maintaining good dog eye health involves understanding the warning signs, getting timely vet care, and making adjustments to your dog's home to keep them safe and comfortable. Remember to speak to your veterinarian if you have any concerns about your dog's eye health. Early detection and treatment are vital for preserving your dog's vision.
