Understanding Cataracts in Cats
Cataracts in cats are a condition characterized by changes to the clear lens inside the eye, resulting in a cloudy appearance. This cloudiness can lead to vision changes and even blindness (PetMD). Let’s explore the definition and causes of cataracts in cats, as well as the common breeds and predisposition.
Definition and Causes
Cataracts occur when the lens of the cat’s eye becomes opaque, impairing normal vision. The lens, which is responsible for focusing light onto the retina, should be transparent. However, with cataracts, it takes on a cloudy appearance, hindering the passage of light and affecting visual clarity.
The most common cause of cataracts in cats is chronic uveitis, which is inflammation inside the eye. This inflammation can result from various factors, including infections, diseases, or trauma (PetMD). It is important to address and treat uveitis promptly to minimize the risk of developing cataracts.
Common Breeds and Predisposition
While cataracts can occur in cats of any age, sex, or breed, certain breeds are more predisposed to cataract formation. These include Persian, Birman, Siamese, Russian Blue, and Himalayan cats. These breeds may have a genetic predisposition to developing cataracts, and it is important for owners of these cats to be vigilant for any signs of cataracts.
Genetic predisposition to inherited cataracts has been observed in Himalayan, Birman, and British Shorthair breeds. However, it is worth noting that cataracts can still occur in cats without a breed predisposition.
It is interesting to note that cats with diabetes typically do not develop cataracts, unlike humans and dogs who can develop cataracts as a result of diabetes. Cataracts in cats are more commonly seen in older cats, and certain breeds, such as Burmese and Himalayans, may have a genetic predisposition to the condition.
Understanding the definition, causes, and breed predisposition of cataracts in cats is the first step toward recognizing and addressing this condition. In the following sections, we will explore the symptoms, diagnosis, treatment options, preventive measures, and care for cats with cataracts.
Symptoms and Diagnosis
Cataracts in cats can cause a significant impact on their vision. Recognizing the symptoms and seeking timely diagnosis is crucial for proper management and treatment. Let’s explore how to recognize cataracts in cats and the diagnostic procedures involved.
Recognizing Cataracts in Cats
Identifying the signs of cataracts in cats can help pet owners seek prompt veterinary care. Here are some common symptoms to watch out for:
-
Cloudy or Hazy Appearance: Cataracts cause the lens of the eye to become opaque, resulting in a cloudy or hazy appearance. This can be observed by closely examining the cat’s eyes.
-
Change in Eye Color: The affected eye may exhibit a change in color due to the opacity of the lens.
-
Vision Changes: Cats with cataracts may show signs of vision impairment, such as decreased visual acuity, reluctance to navigate unfamiliar environments, or bumping into objects.
-
Altered Behavior: Cats may display altered behavior, such as increased sensitivity to light or reluctance to engage in activities that require clear vision.
If you notice any of these signs, it’s recommended to consult a veterinarian for a thorough examination and diagnosis. For more details on the signs and symptoms of cataracts in cats, refer to our article on cat cataract symptoms.
Diagnostic Procedures
To diagnose cataracts in cats, veterinarians perform an ophthalmic examination using a specialized instrument called an ophthalmoscope. This tool allows them to assess the internal structures of the eye, including the lens. Abnormal opacities within or on the surface of the lens indicate the presence of cataracts (VCA Canada).
During the examination, the veterinarian will carefully evaluate the cat’s eyes for any signs of cataracts. They may also conduct additional tests, such as a visual acuity assessment, to determine the extent of vision impairment caused by the cataracts.
It’s important to note that cataracts can sometimes be associated with underlying health conditions. Therefore, the veterinarian may recommend further diagnostic tests, such as blood work, to rule out any potential underlying causes.
Early diagnosis of cataracts is crucial for assessing the best treatment options and preventing further vision deterioration. If your cat is displaying symptoms of cataracts, it’s essential to schedule a veterinary appointment for a comprehensive evaluation and diagnosis.
In the next section, we will explore the various treatment options available for cataracts in cats. Stay tuned to learn about surgical intervention, medication, and management techniques to address this condition effectively.
Treatment Options
When it comes to treating cataracts in cats, there are two primary options: surgical intervention and medication management.
Surgical Intervention
Surgery is often the most effective treatment for cataracts in cats. The procedure, known as phacoemulsification, involves removing the cloudy lens and replacing it with an artificial lens. This surgery is typically performed by a veterinary ophthalmologist.
Cataract surgery for cats is highly recommended for those who qualify. The procedure aims to restore vision and improve the quality of life for the cat. Post-surgery care is crucial and may involve applying topical eye medicine for several months. Additionally, the cat may need to be kept in a confined space for at least three weeks to prevent complications such as swelling and bleeding.
Here are some key points about cataract surgery for cats:
- Surgery is performed by a veterinary ophthalmologist using phacoemulsification technique (PetMD).
- The lens is removed and replaced with an artificial lens (Hill’s Pet).
- Post-surgery care involves applying topical eye medicine and monitoring for complications.
- Surgery is ideal for cats without significant eye inflammation.
- Cataract surgery is most successful in kittens and mature cats in good health (All About Vision).
Medication and Management
In some cases, surgery may not be feasible or suitable for a cat with cataracts. However, medications can be used to manage the condition and prevent complications. Medications such as corticosteroids or non-steroidal anti-inflammatory eye drops may be prescribed to decrease inflammation within the eye and reduce the risk of additional issues like glaucoma. These medications aim to improve the cat’s overall eye health and prevent further deterioration.
Here are some important points about medication and management for cataracts in cats:
- Medications like corticosteroids or non-steroidal anti-inflammatory eye drops can be used to decrease inflammation within the eye.
- Cats with diabetes typically don’t develop cataracts, and medication management is not a primary treatment option for cataracts in cats.
- Preventive measures, such as regular veterinary visits, vaccinations, and treating underlying health issues like diabetes and high blood pressure, can help maintain overall eye health and potentially reduce the risk of cataracts.
It’s important to consult with a veterinarian to determine the best course of treatment for your cat’s specific situation. They will be able to provide personalized recommendations based on the cat’s overall health, age, and severity of the cataracts.
Preventive Measures
When it comes to cataracts in cats, taking preventive measures can be beneficial in maintaining your feline companion’s eye health. While some factors contributing to cataracts are beyond our control, there are steps you can take to minimize the risk and promote overall eye health.

Complications and Risks
Cataracts in cats can lead to various complications and risks if left untreated. It’s important for cat owners to be aware of these potential issues and understand the long-term management options available.
Potential Issues
Untreated cataracts in cats can lead to complications such as glaucoma. Glaucoma occurs when the lens slips out of its normal location, blocking ocular fluid drainage and causing pressure build-up that can damage the retina cells. Cats with glaucoma may exhibit symptoms such as a “red eye” appearance, squinting, and experiencing pain.
Advanced cataracts in cats can result in failing vision or blindness. Cats may exhibit signs such as moving slowly, becoming less agile, bumping into furniture, or having difficulty finding their food bowl or litterbox. These signs indicate a significant impact on their vision and daily activities. Additionally, cats with advanced cataracts may experience hazy vision in certain types of light, have difficulty navigating around the home, and struggle with tasks such as going up or down stairs or finding food.
While cataracts themselves are not considered painful, some conditions that cause them can be. It’s important to observe signs such as squinting, discharge, redness, and swelling around the eye. Cats are adept at hiding discomfort, so it’s crucial to be vigilant in detecting potential vision changes.
The underlying causes of cataracts in cats can vary, including metabolic disorders, diabetes, hypertension, traumatic injury, exposure to certain drugs or toxic substances, radiation, or electric shock. In many cases, the exact cause of cataracts in cats remains unknown.
Long-Term Management
In cases where surgery is necessary, it is typically the ideal treatment for feline cataracts. The surgical procedure involves making small incisions in the cornea and lens capsule, disintegrating and removing the affected lens using high-frequency sound, inserting an artificial lens, and suturing the incision. This surgery, which typically lasts about an hour, is successful in most kittens and mature cats who are good candidates for lens implantation.
Post-surgery care may include wearing a protective cone and administering eye drops frequently. It’s crucial to follow the veterinarian’s instructions for proper post-surgery care to ensure the best recovery and outcome for the cat (Daily Paws). Regular monitoring and follow-up appointments with the veterinarian are essential to evaluate the progress of the cat’s vision and overall eye health.
Long-term management of feline cataracts may involve ongoing monitoring, especially in cases where surgery is not performed or when cataracts are not causing significant impairment. Your veterinarian can provide guidance on managing the condition and recommend any necessary treatments or lifestyle adjustments to support your cat’s eye health.
By understanding the potential complications and risks associated with cataracts in cats, cat owners can take proactive steps to seek appropriate treatment and provide the necessary care to maintain their feline companion’s well-being.
