In humans, cataracts are the world's leading cause of blindness. Cataracts in cats are rare, but the disease is still serious; if left untreated, it may lead to blindness. Thankfully, many cases of feline cataracts can be successfully treated.
Cataracts affect the lens of the eye. The lens helps to focus vision as light that passes through the eye, allowing your cat to see. If this small structure becomes cloudy due to a cataract, it can no longer focus light resulting in blurry vision. The lens is made of mostly proteins and water. Clouding of the lens occurs due to changes in the proteins and lens fibers.
Cataracts in cats are less common than they are in humans and dogs. Furthermore, while humans and dogs can develop cataracts due to diabetes, cats with diabetes typically don't get cataracts. They are also most common among older cats, and Burmese and Himalayan cats are genetically predisposed to the condition. However, cats of all ages and breeds can be affected.
Cataracts in cats can develop due to:
Cataracts may develop as a result of uveitis, a type of eye inflammation that can occur as a result of infectious diseases like feline immunodeficiency virus, feline leukemia virus, feline infectious peritonitis and toxoplasmosis. However, it's not always possible to identify the cause of cataracts.
Cats are very good at hiding discomfort and vision changes, so it's crucial to look for potential signs of cataracts, such as:
While cataracts aren't considered painful, some conditions that cause them can be. Because of this, a cat with cataracts might also squint or have discharge, redness and swelling around the eye.
To diagnose cataracts, your veterinarian may perform a variety of tests such as the eye exam and pressure tests. While general practitioners can diagnose most cataracts, they may refer you to a specialist such as veterinary ophthalmologists, who can conduct more sophisticated tests.
These tests may include:
If your vet either suspects or diagnoses cataracts in your cat, your veterinarian may recommend that you see a board certified Veterinary Ophthalmologist for further testing and treatment.
Cataracts are classified according to severity and percentage of the lens affected. These are the classifications, according to Animal Eye Clinic:
Diagnosing the stage of feline cataracts is essential to selecting the best treatment option.
Identifying and addressing the underlying cause of cataracts is the primary approach to treatment. Once this is determined, definitive measures to delay or prevent cataract-related blindness can be considered.
Here are some common approaches:
Removing and replacing the lens with a prosthetic lens is strongly recommended for cats who qualify. If your cat receives cataract surgery, there are important steps you can take to help your cat recover.
For several months after surgery, you'll likely need to apply topical eye medicine. You must also keep your cat in a confined space for at least three weeks, as complications like swelling and bleeding may occur. A pet cone is a must, too.
Feline cataracts can occur in kittens as a result of inadequate nutrition. A study of hand-reared tigers in Open Veterinary Journal seems to support this. Adequate intake of amino acids (the building blocks of protein) are important for eye development in tigers. Presumably, the same is true when it comes to reducing the risk of cataracts in domestic cats.
What's more, studies in humans, like one in Nutrition Reviews, suggest that the risk of cataracts might be reduced with appropriate nutrition, especially intake of antioxidant vitamins, like vitamin C, as well as lutein, B vitamins, omega-3 fatty acids. A properly balanced pet food for your cat's life stage can often provide the essential nutrients to support your cat's eye health.
