What Causes Blindness in Cats?

Blindness in cats can occur due to several reasons, ranging from congenital defects to age-related degeneration. Let’s dive deeper into the main causes of blindness in cats and how to prevent it.

Congenital Defects:

Some cats are born with congenital defects, such as retinal dysplasia, which is characterized by abnormal development of the retina. These defects can lead to partial or complete blindness in cats. Other congenital abnormalities that can result in blindness include coloboma, optic nerve hypoplasia, and microphthalmia.


Cats are naturally curious creatures and can get into trouble sometimes. They can sustain eye injuries from blunt trauma or penetrating injury that damages the optic nerve or retina. Head trauma can also cause blindness in cats. Common accidents that cause injury include car accidents, fights with other animals, and falls.


Certain infections such as FIV, FeLV, and FIP can cause blindness in cats. They may affect the eyes directly or indirectly by impacting the cat’s immune system. Additionally, some treatments for these infections can lead to blindness as a side effect. Other infections that can lead to vision loss include toxoplasmosis, herpesvirus, and chlamydia.

Age-Related Degeneration:

As cats age, their body systems begin to wear out, and their eyes are no exception. Older cats may develop age-related eye problems such as cataracts, glaucoma, or retinal degeneration that can ultimately lead to blindness. Some breeds of cats, such as Siamese and Persian cats, may be more prone to developing age-related eye problems than others.

Signs of Blindness in Cats:

It’s crucial to recognize the signs of vision loss in your cat to provide timely care and treatment. Some common signs include cloudiness or opacity in the eyes, changes in pupil size or response to light, difficulty navigating their environment, and changes in eye color. If you notice any of these symptoms, it’s essential to consult with a veterinarian immediately.

Preventing Blindness in Cats:

Signs of Blindness in Cats

While it may be hard to detect at first, blindness in cats is a serious condition that can have a significant impact on their daily lives. Luckily, there are certain signs that can help you identify if your pet is experiencing vision loss.

The first and most noticeable sign that your cat may be blind is when they start bumping into objects or furniture that they previously navigated with ease. This sudden clumsiness could indicate that your cat is struggling to see as well as they once did. Additionally, keep an eye out for changes in their eye appearance such as cloudiness, haziness, or a bluish-gray tint. These changes may be caused by conditions such as cataracts, glaucoma, or progressive retinal atrophy.

If your cat seems more hesitant or fearful of their surroundings, this could also be a sign of vision loss. They may startle easily when approached or touched and may not respond to visual cues like toys or movements. Some cats may even become more vocal or clingy as they try to navigate their environment. This sudden change in behavior indicates that your cat is experiencing discomfort and confusion due to their blindness.

It’s also important to watch for signs of eye discomfort like excessive blinking, squinting, or tearing. These symptoms could indicate an underlying eye infection or injury that needs prompt attention from a veterinarian. As a responsible owner, it’s crucial to get your cat examined by a professional if you notice any of these symptoms.

Cloudiness or Opacity in the Eyes

The eyes of your beloved feline are a window into their soul. Those captivating eyes can reveal a lot about their health, including cloudiness or opacity, which can be a sign of cataracts. Cataracts are a common condition that causes the lens of the eye to become cloudy, resulting in vision loss and potential blindness if left untreated. As an expert in this area, I can attest that cat owners must be vigilant and seek veterinary care at the first sign of this issue.

When left untreated, cataracts can lead to blindness, which can be disorienting for your furry friend. You may notice a cloudy or opaque appearance in one or both eyes. Cats with cataracts may also have difficulty seeing in low light conditions or may bump into objects they previously avoided. They may become more sensitive to light and squint or avoid bright areas altogether.

It is essential to note that not all cases of cloudiness or opacity in the eyes are caused by cataracts. Other potential causes include glaucoma, uveitis, and corneal ulcers. Therefore, it is crucial to consult with a veterinarian to determine the underlying cause and appropriate treatment options.

In some severe cases, surgery may be necessary to remove cataracts and restore vision in cats. However, this option is not always viable for every cat. Nevertheless, with proper care and treatment, many cats with vision loss due to cataracts can still lead happy and fulfilling lives.

Change in the Size of the Pupil

As an expert in this area, I wanted to share some insights on this topic and help you understand what to look out for.

Changes in pupil size can be caused by various factors such as age, environment, and underlying health conditions. However, when it comes to vision loss, one of the most noticeable changes is the size of the pupils. Here are some sub-topics to consider:

Abnormal Pupil Size:

If you notice that your cat’s pupils appear larger or smaller than usual, it could be a sign that their vision is deteriorating. Additionally, their pupils may react differently to light or become permanently dilated, making it difficult for them to see in bright environments.

Loss of Retina Function:

The retina plays a crucial role in sensing light and regulating the size of the pupil. When the retina deteriorates, it can no longer function properly and regulate the size of the pupil effectively. This can lead to abnormal pupil size.

Cloudy or Hazy Lens:

Changes in the lens of the eye can cause a cat’s pupils to become cloudy or hazy, which further affects their ability to see clearly. This can also lead to abnormal pupil size.

Other Eye Conditions:

It’s important to note that changes in pupil size can also be a symptom of other eye conditions or diseases such as glaucoma or uveitis. Therefore, if you notice any abnormal changes in your cat’s pupils or if they’re experiencing other symptoms such as redness or discharge from their eyes, it’s essential to have them examined by a veterinarian as soon as possible.

In summary, changes in the size of your cat’s pupil can be an indication that their vision is deteriorating. As a responsible pet owner, it’s crucial to monitor any changes in your cat’s eyes and seek medical attention if necessary to prevent further damage and ensure their overall health and well-being.

Difficulty Navigating Their Environment

However, when a cat starts to lose their sight, their once graceful movements can become uncoordinated and uncertain. Difficulty navigating their environment is one of the most noticeable changes that occur when cats start to go blind. Their ability to move around confidently and gracefully diminishes, and they may begin to bump into objects, stumble, or even fall over. This can be alarming for both the cat and their owner.

The loss of vision plays a significant role in a cat’s coordination and balance. When their eyesight starts to deteriorate, it can disrupt their sense of spatial awareness, causing them to misjudge distances. Cats rely heavily on their vision to navigate in low-light environments. Losing their ability to see clearly can also affect their movement in dimly lit areas.

Owners may notice their cat avoiding certain areas of the house or becoming more hesitant to jump up onto high surfaces. They may also become more vocal or clingy, seeking reassurance and guidance from their owner. Patience is essential when dealing with a blind or visually impaired cat. Providing them with a safe and familiar environment, as well as plenty of love and support, can help them cope.

To help blind or visually impaired cats navigate their surroundings more efficiently, owners can employ practical steps such as keeping furniture and objects in the same place. Using mats or rugs provides tactile cues that help cats move around more easily. Owners can also provide plenty of vertical surfaces for the cat to climb on, which helps them feel secure and confident in their movements.

Scent markers or vocal cues can also guide a blind or visually impaired cat through the house. These aids are especially helpful in larger houses or if there are multiple levels that the cat needs to navigate.

Change in Eye Color

However, just like humans, cats can experience health issues as they age. One of the noticeable changes that can occur in a cat’s eyes is a change in eye color. In this blog post, we will explore what causes this change and what it could signify for your furry companion.

As cats age, the lens inside their eyes becomes less clear and more opaque, resulting in cloudiness or haziness in their eyes. This cloudiness can cause a loss of vibrancy in the iris, resulting in a duller eye color. Cataracts are also common in older cats and can cause cloudiness in the eyes, which can affect the cat’s eye color.

But not all cloudy or dull eyes indicate blindness. It could be an indication of an underlying health issue that needs attention from a veterinary professional. Therefore, it is crucial to have your cat examined by a veterinarian if you notice any changes in their eye color or clarity.

Some breeds of cats are more prone to developing certain eye conditions that can lead to blindness. For instance, Siamese cats are susceptible to progressive retinal atrophy, which can cause them to go blind over time. Persian cats are also at a higher risk of developing cataracts and glaucoma.

Keeping an eye on your cat’s eye health as they age is essential. Regular visits to the veterinarian can help catch any underlying health issues early on, preventing further damage to your cat’s eyesight. If your cat does experience a change in eye color or clarity, don’t hesitate to seek veterinary care.

To sum up, a change in eye color is one of the noticeable signs when a cat’s eyes start to go blind. However, it could also be an indication of an underlying health issue. As such, it is vital to have your cat examined by a veterinarian if you notice any changes in their eye health. By being vigilant and proactive, you can help ensure your feline companion enjoys a happy and healthy life for years to come.

Discharge or Redness Around the Eyes

One of the most common signs that something is amiss is discharge or redness around their eyes. While it can be worrying, this is a symptom that can be caused by several factors, including infections, allergies, or injury.

Infections are a prevalent cause of discharge and redness in a cat’s eyes. Conjunctivitis, for example, can cause inflammation of the conjunctiva – the thin membrane that covers the white part of the eye. This inflammation leads to discharge, redness, and swelling around the eyes. You may notice your cat rubbing their eyes frequently or even avoiding bright lights.

Allergies are another common culprit for discharge and redness in a cat’s eyes. Your feline friend can be allergic to various things such as pollen, dust mites, or certain foods. When exposed to allergens, their immune system reacts, leading to inflammation and irritation in the eyes. Your cat may rub their eyes frequently or squint if they have allergies.

Injury is also a factor that can cause discharge or redness in a cat’s eyes. Trauma to the eye can cause damage to the cornea or other parts of the eye, leading to inflammation and discharge. Scratches from other animals or foreign objects can also cause injury to the eye.

If you notice any discharge or redness around your cat’s eyes, it’s crucial to take them to the vet for an examination. Your vet will be able to diagnose the underlying cause of these symptoms and provide appropriate treatment. In some cases, medication may be necessary to clear up infections or alleviate allergies. In more severe cases, surgery may be required to treat injuries or other underlying conditions.

Treatment Options

Fortunately, there are various treatment options available to help improve their quality of life. Let’s explore these options together.

Consulting with a veterinarian is crucial in determining the best treatment option for your cat. Medication may be prescribed if the blindness is caused by an infection or inflammation, which can reduce symptoms and improve their vision. However, it’s important to note that medication isn’t always a suitable treatment for all causes of blindness.

Surgery is another potential option for cats with cataracts or other eye conditions that can be corrected through surgical procedures. However, this can be a pricey option and may not always be successful in restoring vision.

Environmental modifications can also assist blind cats in navigating their surroundings more comfortably. This could include providing ramps, using scent markers to help them find their way around, and ensuring that there are no obstacles in their path.

Finally, offering blind cats plenty of love and attention is crucial. It can be a scary experience to lose one’s sight, so creating a safe and comfortable environment for them is important. Giving them lots of affection and reassurance helps mitigate any anxiety they may feel.


As a devoted cat parent, it’s crucial to stay on top of any signs that your feline friend may be losing their vision. Keep an eye out for changes in their eyes, such as cloudy or hazy pupils, unresponsive irises, or a lack of clarity. These could all be indicators that your cat is experiencing vision loss.

There are several reasons why cats may go blind, including injury, infections, and age-related degeneration. Common causes of feline blindness include cataracts, glaucoma, and retinal degeneration. By recognizing the symptoms of these conditions early on and seeking prompt medical attention from a veterinarian, you can help prevent blindness in your beloved pet.

If your cat does experience vision loss due to conditions such as cataracts or glaucoma, there are various treatment options available. Depending on the cause of the blindness, medication or surgery may be recommended. With proper care and treatment, many cats with visual impairments can continue to live happy and fulfilling lives.

In conclusion, taking an active role in your cat’s eye health is essential for ensuring their well-being. Regular visits to the vet can help catch any underlying health issues early on and provide timely care and treatment.
