Cats are beloved pets that bring joy and companionship to many families around the world. However, despite their many charms, cats are also prone to a range of health issues that can affect their vision and cause blindness. In fact, blindness is a common problem in cats, with estimates suggesting that up to 20% of cats over the age of 12 may experience some degree of vision loss. As a responsible cat owner, it’s essential to understand the causes of blindness in cats and what you can do to help prevent or manage the condition.
What Causes Blindness in Cats?
Blindness in cats can be caused by a range of factors, including genetics, age-related decline, and various medical conditions. Some common causes of blindness in cats include:
Genetic Conditions
Certain genetic conditions, such as progressive retinal atrophy, can cause blindness in cats. These conditions are often inherited and can affect cats of any age.
Age-Related Decline
As cats age, their vision can decline due to the natural aging process. This decline can be gradual, with older cats experiencing reduced visual acuity and sensitivity to light.
Medical Conditions
Various medical conditions, such as cataracts, glaucoma, and retinal detachment, can also cause blindness in cats. These conditions can be caused by injury, infection, or other factors.
Other Factors
In addition to genetic and age-related factors, other factors can contribute to blindness in cats, including:
- Eye injuries or trauma
- Infections, such as conjunctivitis or uveitis
- Systemic diseases, such as diabetes or hypertension

What Causes Blindness in Cats
Cats are known for their keen senses, particularly their vision. However, like humans, they can also experience vision loss or blindness due to various reasons. Blindness in cats can be a challenging condition for both the cat and its owner, requiring significant adjustments to their daily routine and environment.
Causes of Blindness in Cats
Blindness in cats can be caused by a variety of factors, including:
- Genetic Conditions: Certain breeds, such as the Sphynx and the Devon Rex, are prone to vision loss due to genetic defects.
- Infections: Feline infectious peritonitis (FIP) and feline leukemia virus (FeLV) can cause vision loss in cats.
- Injuries: Trauma to the eyes, such as a blow to the head or a penetrating injury, can lead to blindness.
- Diseases: Conditions such as cataracts, glaucoma, and retinal dysplasia can cause vision loss in cats.
- Aging: As cats age, their vision can decline due to age-related changes in the eyes.
- Nutritional Deficiencies: A lack of essential nutrients, such as vitamin A, can contribute to vision loss in cats.
Signs of Blindness in Cats
Cats with blindness may exhibit the following signs:
- Increased Sensitivity to Light: Blind cats may become more sensitive to light and may avoid bright areas.
- Difficulty Navigating: Blind cats may have trouble navigating their surroundings and may bump into objects or furniture.
- Increased Vocalization: Blind cats may vocalize more frequently due to their inability to navigate their environment.
- Changes in Behavior: Blind cats may exhibit changes in behavior, such as increased anxiety or aggression, due to their vision loss.
Diagnosing Blindness in Cats
Diagnosing blindness in cats typically involves a combination of physical examination, medical history, and diagnostic testing. The following tests may be performed:
- Ophthalmic Examination: A thorough examination of the eyes to check for signs of disease or injury.
- Visual Acuity Testing: A test to assess the cat’s ability to see and respond to visual stimuli.
- Electroretinography (ERG): A test that measures the electrical activity of the retina to diagnose retinal diseases.
- Imaging Studies: X-rays, CT scans, or MRI scans may be used to rule out other conditions that may be causing the blindness.
Treatment and Management of Blindness in Cats
There is no cure for blindness in cats, but there are various treatments and management strategies that can help improve the cat’s quality of life:
- Environmental Adaptations: Making changes to the cat’s environment, such as removing obstacles and providing a stable and familiar space, can help the cat navigate more easily.
- Assistive Devices: Using assistive devices, such as a harness and leash, can help the cat move around more safely and confidently.
- Pharmacological Treatment: Medications may be prescribed to manage symptoms such as pain, anxiety, or depression.
- Surgery: In some cases, surgery may be necessary to correct underlying conditions, such as cataracts or glaucoma.

Here are five FAQs related to “What Causes Blindness In Cats”:
Frequently Asked Questions: What Causes Blindness In Cats
What are the most common causes of blindness in cats?
The most common causes of blindness in cats include cataracts, progressive retinal atrophy, and glaucoma. Cataracts occur when the lens in the eye becomes cloudy, while progressive retinal atrophy is a degenerative condition that affects the retina. Glaucoma is a condition that occurs when there is increased pressure in the eye, which can damage the optic nerve and lead to blindness.
Can cataracts be treated in cats?
Yes, cataracts in cats can be treated with surgery. The surgery involves removing the cloudy lens and replacing it with an artificial lens. However, the surgery is typically only recommended for cats that are still young and have a good quality of life. For older cats or those with other health issues, the surgery may not be recommended due to the risks involved. (See Also: How To Make Cats Like You)
What are the symptoms of progressive retinal atrophy in cats?
The symptoms of progressive retinal atrophy in cats can vary depending on the stage of the condition. In the early stages, cats may exhibit no symptoms at all. As the condition progresses, cats may experience night blindness, difficulty seeing in bright light, and eventually complete blindness. They may also exhibit behavioral changes such as increased anxiety or aggression.
Can glaucoma be treated in cats?
Glaucoma in cats can be treated with medication or surgery. Medication can help to reduce the pressure in the eye and slow the progression of the condition. Surgery may be necessary if the condition is advanced or if the cat is not responding to medication. The surgery involves removing the affected eye or performing a procedure to reduce the pressure in the eye.
How can I prevent blindness in my cat?
While it’s not possible to completely prevent blindness in cats, there are steps you can take to reduce the risk. Regular veterinary check-ups can help to detect any eye problems early on, and providing a healthy diet and a safe living environment can help to reduce the risk of eye injuries. Additionally, keeping your cat indoors can help to reduce the risk of eye injuries caused by outdoor hazards such as traffic or other animals.
