Cats rely on sharp vision to navigate their surroundings and even communicate with their owners. Such a situation will prove distressing for both the feline and the pet parent. Knowing what causes blindness in cats, identifying the early warning signs, and knowing how to respond are key steps that need to be taken. Here, you will find the 5 common causes for blindness in cats, effective treatments, and proactive measures to keep your feline companion healthy and happy.
Understanding Blindness in Cats
Blindness can occur gradually or be sudden in cats. Cats adapt surprisingly well to their loss of eyesight, and they will rely mainly on their acute sense of smell and ears. Early detection and treatment are essential. Keeping an eye out for early symptoms and making yourself informed about the cause can help dramatically regarding quality of life.
1. Hypertension (High Blood Pressure)
What Is Hypertension in Cats?
Hypertension is one of the common causes for blindness in cats, and it usually exists with other diseases, such as chronic renal failure or hyperthyroidism. High blood pressure can damage the minimal blood vessels of the eye by detaching the retina or causing a hemorrhage, and this leads to vision loss.
Signs of Vision Loss Due to Hypertension
- Dilated pupils that don’t react to light
- Bumping into objects or difficulty navigating familiar spaces
- Visible blood or redness in the eyes
- Symptoms of associated health problems, like weight loss, increased thirst, or lethargy
Treatment Options
Medication: Antihypertensives are prescribed to manage raised blood pressure and further injury.
Treating Underlying Conditions: Kidney disease or overactive thyroid may be a controllable cause of hypertension.
Routine Monitoring: Veterinary visits are scheduled regularly to check blood pressure and eyes.
Tip for dog and cat owners: Senior cats and cats with certain pre-existing conditions should have their blood pressure checked regularly to detect problems in advance.

2. Retinal Deterioration
It refers to a constant drop in the health and functionality of the retina, a pivotal tissue at the back of the eye that converts light into neural signals.
This condition may emerge due to hereditary concerns, making it innate, or be activated by dietary deficiencies, such as insufficient levels of taurine, an essential amino acid. As the retina breaks down, its capacity to process visual information decreases, in the long run causing limited or total loss of vision on the off chance left untreated.
Symptoms to Watch For
- Night blindness or difficulty seeing in dim light
- Wider-than-normal pupils that don’t constrict in bright conditions
- Bumping into objects in unfamiliar or poorly lit areas
Treatment and Support
- Dietary Modifications: Since this disease results from taurine deficiency, supplementation of sufficient taurine in the diet gives relief from the condition.
- Environmental Changes: Maintain your cat’s environment as non-changing and uncluttered, which can facilitate easier navigation.
- Regular eye exams: Routine check-ups with the vet would help in early and frequent detection and follow-up.
Fun fact: Some breeds, such as Abyssinians and Siamese cats, are more prone to retinal degeneration. Knowing your cat’s genetic risk can guide early intervention.
Related Tip: Feed your cat a balanced diet that will contain the nutrients for healthy eyesight.
3. Glaucoma
What Is Glaucoma?
It refers to the destruction of the optic nerve caused by the increase of pressure in the eye that may ultimately lead to visual impairment. It can be caused by infections, trauma, inflammation, or even hereditary.
Recognizing the Symptoms
- Redness and swelling in the eyes
- A cloudy cornea that may appear bluish or foggy
- Frequent squinting or rubbing the eyes with their paws
- Rapid vision deterioration, sometimes accompanied by signs of pain
Treatment Options
- Medicated eye drops: These are given primarily to reduce intraocular tension and manage pain.
- Surgery: In most radical cases, surgery may be performed to release pressure or even remove the eye if it is causing too much pain.
- Pain control: Your cat must be kept comfortable while conducting the treatment.
Prevention Tip: Remember to always look out for any change in the eye color or behavior of your feline. Timely veterinary attention can indeed avoid irreversible damage.

4. Infections & Inflammatory Diseases
Generally, cats are vulnerable to eye infections & inflammatory concerns. Their main causes are viruses such as feline herpesvirus, bacteria, or parasites such as toxoplasmosis. They are responsible for ulcers in the cornea, inflammation, and even permanent loss of vision.
Symptoms of Eye Infections
- Watery or pus-like discharge from the eyes
- Redness and swelling around the eye area
- Sensitivity to light and frequent blinking
- Pawing at the eyes or rubbing against surfaces
Treatment Strategies
- Antibiotics or Antivirals: According to the cause, your vet will prescribe topical or oral antibiotics.
- Anti-Inflammatory Medications: To reduce swelling and ease pain.
- Follow-up Care: Close monitoring for evidence of resolution of the infection and for prevention of complications.
- Preventive Measures: Keep the cat’s vaccinations updated and ensure that their environment remains clean to decrease the chances of infections.
Useful Tip: Observe your feline friend’s grooming habits and his facial expressions. The changes imply irritation, and sometimes, even distress.
5. Trauma or Injury
How Does Trauma Affect Vision?
In cats, an insatiable curiosity sometimes gets them into trouble. Physical trauma to the eye from fights falls, or accidents can cause bleeding, retinal detachment, or damage to nerves within the eye, often resulting in sudden or gradual loss of vision.
Signs of Eye Trauma
- Bleeding or discharge from the eye
- Swelling or a sudden change in eye color
- Bulging or sunken appearance of the eye
- Reluctance to move or navigate as usual
Treatment and Recovery
- Emergency veterinary care: Any eye injury is considered an emergency so that no permanent damage occurs.
- Surgical intervention: It may be needed and sometimes, in the worst instance, removal of the eye to restore the damage.
- Home Safety: Always avoid any unsafe objects and closely watch outdoor activities to minimize the probability of getting hurt.
Home Tip: If the cat loves climbing or gets involved in outdoor adventures, this safety measure may prevent accidents.
