What to Do If Your Dog Has Cataracts? A Complete Guide to Causes, Symptoms, Treatment, and Care
When a dog develops cataracts, it may experience blurry vision, cloudy eyes, dryness, and even difficulties in daily activities, significantly impacting its quality of life. This article provides an in-depth look at the stages of cataract symptoms, six common causes, three treatment options, and essential nutrients to support your dog’s eye health through proper daily care.
1. What Are Canine Cataracts? What Are the Early Signs?
(1) What Are Canine Cataracts?
Cataracts are a common eye condition in dogs caused by the clouding of the lens, leading to vision impairment. This can affect night vision, cause light sensitivity, and even result in eye redness or inflammation.
Since dogs cannot verbally express their vision problems, owners should observe their behavior and eye appearance to identify potential signs of cataracts.
(2) Early Signs of Cataracts in Dogs
- White or Cloudy Film in the Pupil
Cataracts cause the lens to become cloudy, making a white or grayish film visible in the dog’s eye, similar to a foggy layer covering the eyeball.
⚠ Note: Not all cloudy eye conditions are cataracts. Aging can also cause nuclear sclerosis, which does not necessarily affect vision. Always look for additional symptoms or consult a veterinarian for confirmation.
- Glazed Expression and Difficulty Focusing
The clouding of the lens obstructs light from reaching the retina, making it difficult for dogs to see clearly. They may bump into furniture, appear to have an empty stare, or have trouble focusing. Some may even lose interest in toys or bark at nothing. - Excessive Tearing or Eye Discharge
Cataracts can cause eye inflammation, leading to increased tear production. Look out for redness, frequent tearing, or excessive eye discharge. - Frequent Squinting or Blinking
Due to impaired vision, dogs may squint or blink excessively as they try to focus on objects. - Dry Eyes and Light Sensitivity
If your dog experiences dry eyes, discomfort in bright light, or frequently rubs its eyes with its paws, it may be a reaction to cataracts.
If any of these symptoms are present, it is important to seek veterinary attention early to ensure timely diagnosis and treatment.
(3) Difference Between Cataracts and Nuclear Sclerosis
According to veterinary sources, cataracts and nuclear sclerosis are two different conditions:
- Nuclear Sclerosis: A normal aging process that causes the lens to harden and appear white, but it does not affect vision or cause inflammation. No treatment is required.
- Cataracts: Clouding of the lens that impairs vision and may cause inflammation. It requires medical attention.
Since these two conditions may look similar, a veterinarian should diagnose the condition to ensure appropriate care.
2. What Causes Cataracts in Dogs? 6 Common Factors
According to PetMD, the main causes of canine cataracts include:
- Genetics
Certain breeds, such as Poodles, French Bulldogs, Labradors, and Schnauzers, are prone to hereditary cataracts, which can develop as early as 1–5 years old. - Aging
As dogs age, their lenses may naturally become cloudy. This is a common cause of cataracts, typically progressing slowly. - Eye Diseases
Conditions like glaucoma, uveitis, corneal ulcers, or eye injuries can lead to internal eye inflammation, affecting lens transparency and causing cataracts. - Endocrine Disorders
Diabetes can cause lens protein degeneration, leading to cataracts. Other hormonal disorders, such as hypothyroidism, may also increase the risk. - Medications or Toxic Exposure
Certain drugs, such as steroids, antifungal medications, and dewormers, may affect lens clarity. Additionally, exposure to environmental toxins like organic solvents can lead to eye disease. - Environmental Factors
Prolonged UV exposure and poor nutrition may negatively impact lens health, accelerating cataract formation.
3. Symptoms and Possible Complications of Canine Cataracts
Cataract symptoms progress through different stages:
- Early Stage: The lens begins to cloud, causing minor vision loss. Dogs may struggle to see in the dark or seem less responsive to their surroundings.
- Middle Stage: The eye appears noticeably white, and vision impairment becomes significant. Dogs may become less active, hesitant to move, or even get lost in familiar spaces.
- Late Stage: The cloudiness worsens, potentially leading to total blindness. Severe cases may result in complications such as glaucoma, eye inflammation, or lens dislocation.
4. How to Treat Canine Cataracts? 3 Treatment Options and Costs
(1) Early Stage: Conservative Treatment (Eye Drops)
Best for: Dogs with mild symptoms or owners who prefer not to pursue surgery.
Method: Eye drops can help reduce inflammation and discomfort but cannot reverse cataracts.
(2) Middle to Late Stage: Surgical Treatment
The two most common cataract surgery methods are:
- Phacoemulsification (Ultrasound Cataract Surgery)
This procedure uses ultrasound waves to break up the cloudy lens, which is then removed and replaced with an artificial lens. Success rates are 80–90%. - Extracapsular Cataract Extraction (ECCE)
This method removes the cloudy lens and replaces it with an artificial one, suitable for special medical conditions.
✅ Estimated Cost:
Surgery costs vary depending on the clinic, equipment, and the dog’s condition. The price for surgery on one eye typically ranges from 40,000–80,000 TWD. Postoperative care and follow-ups are necessary.
5. Common Questions About Canine Cataracts
Q1: Can Cataracts Be Cured?
Surgery is currently the only effective way to restore vision. Eye drops and medications can only slow down the progression.
Q2: Can Cataracts Be Managed Without Surgery?
Yes, but only to slow progression. If cataracts worsen and affect the dog’s quality of life, surgery is recommended.
Q3: Will a Dog’s Vision Be Fully Restored After Surgery?
The degree of recovery depends on the severity of the condition and postoperative care. Most dogs show significant improvement, but full restoration is not guaranteed.
Q4: How Can I Protect My Dog’s Eye Health?
Regular eye check-ups, a diet rich in eye-supporting nutrients (such as lutein, vitamin A, and Omega-3), and protection from UV exposure and harmful substances can help maintain eye health.
With proper prevention and care, you can help preserve your dog’s vision for as long as possible!
