We've handpicked 27 related questions for you, similar to «What is retinal degeneration and how does it occur?» so you can surely find the answer!
What age does a cat go blind from retinal degeneration?The degeneration process of the retina is slow occurring, but will often lead to total blindness as early as age three and as late as age five. A feline with progressive retinal degeneration will progressively lose the ability to see and may become more cautious about her/his surroundings.
What should I do if my cat has progressive retinal degeneration?
The veterinarian may advise that you have the affected cat spayed or neutered to prevent passing the progressive retinal degeneration gene on to offspring. Progressive retinal degeneration in cats leads to blindness, but a blind cat can have a better quality of life if accommodated by the pet owner.
Is there a cure for progressive retinal degeneration in cats?
Progressive retinal degeneration has no available treatment to cure, slow, or prevent the degeneration of the retina. The degeneration process is occurring due to mutated DNA, which cannot be readily accessed as this is the feline’s genetic makeup.
What is progressive retinal degeneration in cats?
Progressive retinal degeneration is a rare condition in the United States, but has been known to affect purebred cats including the Siamese, Persian, and the Abyssinian.

What causes degenerative retinal degeneration in cats?
The degeneration process is occurring due to mutated DNA, which cannot be readily accessed as this is the feline’s genetic makeup. The veterinarian may advise that you have the affected cat spayed or neutered to prevent passing the progressive retinal degeneration gene on to offspring.
What are the diagnostic tests for retinal degeneration in cats?
Other diagnostic tests will depend on the symptoms your cat is displaying. Your vet may perform a detailed eye examination in order to look for retinal degeneration. The retina requires high amounts of taurine in order to function properly and low levels will cause irreversible degeneration.
Can taurine reverse blindness in cats with retinal degeneration?
While supplementing your cat's diet with taurine can slow down or even stop the progression of retinal degeneration, it won't reverse any blindness your cat may have suffered before supplementation. 1
Can retinal degeneration cause blindness?
This can further lead to separation or detachment of the retina resulting in blindness. Retinal degeneration can also cause blindness and results in a loss of the light sensory cells in the retina.
How is progressive retinal degeneration diagnosed in cats?
A differential diagnosis, which is the act of testing and excluding possible causes of the feline’s symptoms, is the likely method your veterinarian will take to diagnose progressive retinal degeneration. The doctor will begin the diagnostic process by reviewing your cat’s medical history and conducting a physical examination.
How long does it take for taurine deficiency in cats to show?
It can take several months before symptoms become apparent, depending on the cat's life stage. If taurine levels are deficient, the retinal cells of the eyes will eventually degenerate, impairing the vision. This condition is referred to as f eline taurine retinopathy, or more commonly, feline central retinal degeneration (FCRD).
Video answer: What is late onset retinal degeneration (L-ORD)?”
How long does it take for taurine deficiency to affect cats eyes?
It can take between five months and two years before symptoms become apparent, depending on the cat's life stage. If taurine levels are deficient, the retinal cells of the eyes will eventually degenerate, impairing the vision. This condition is referred to as feline central retinal degeneration (CRD).
What is the difference between progressive retinal atrophy and late onset?
Late-onset disorders are characterized by premature degeneration of the photoreceptors after they have developed normally. Progressive retinal atrophy (PRA) is an inherited, bilateral, progressive disease of the retinal photoreceptors that ends in blindness.
What is feline taurine retinopathy?
If taurine levels are deficient, the retinal cells of the eyes will eventually degenerate, impairing the vision. This condition is referred to as feline taurine retinopathy, or more commonly, feline central retinal degeneration (FCRD).
What causes blindness in cats with retinal degeneration?
Blindness due to retinal degeneration can be caused by taurine deficiency in cats. Taurine is an amino acid that cats require as an essential part of their diet. Taurine is normally present in commercial cat foods, and tends to be a problem in cats that are fed imbalanced homemade diets or dog food.
What is pro-progressive retinal atrophy?
Progressive retinal atrophy refers to a group of genetic disorders that cause degeneration and atrophy or wasting away of the retina – a layer of light-sensitive cells located at the back of the eye. It can lead to a continuous decline in the quality of vision and even result in blindness.
Do Bengal cats suffer from retinal atrophy?
This shows that the cat does not suffer from retinal atrophy unless it occurs in future due to other unidentified genetic mutations. A homozygous result which indicates that the cat has two copies of the rdAc genetic mutation. In this case, the Bengal cat will suffer progressive degeneration of the retina.
What are the effects of taurine deficiency in cats?
According to the European Pet Food Industry, FEDIAF deficiency of taurine in felines “can lead to feline central retinal degeneration, dilated cardiomyopathy, and reproductive failure.”
What does lack of taurine do to cats?
This condition is referred to as feline taurine retinopathy, or more commonly, feline central retinal degeneration (FCRD). Deficiency of taurine will also lead to a weakening of the muscle cells in the heart, causing a condition called dilated cardiomyopathy (DCM).
What is Bengal progressive retinal atrophy?
Bengal Progressive Retinal Atrophy (PRA-b) About the disease Bengal PRA-b causes loss of photoreceptors in the eye and ultimately results in blindness. Clinical signs typically become evident between 8 and 20 weeks of age and the disease progresses so that by around one year of age complete retinal degeneration is apparent in most cats1.
What happens if a cat is low in taurine?
If taurine levels are deficient, the retinal cells of the eyes will eventually degenerate, impairing the vision. This condition is referred to as feline central retinal degeneration (CRD). Deficiency of taurine will also lead to a weakening of the muscle cells in the heart, causing a condition called dilated cardiomyopathy.
What is progressive retinal atrophy in Bengal cats?
Progressive Retinal Atrophy. This is another inherited eye disorder Bengal cats are prone to suffer from. The conditions can occur at any time during the cats life but is a painless condition that does affect both eyes until they are completely blind.
What is a breed health DNA test for cats?
A breed health DNA test can also help you determine certain health conditions (such as polycystic kidney disease or retinal degeneration) and hereditary diseases that certain genetic variants in your cat’s DNA might produce in the long run.
How old do cats have to be to go blind?
However, a kitten affected with the mutated gene of progressive retinal degeneration will develop photoreceptors at the same age as a healthy feline, but they will degenerate with age. The degeneration process of the retina is slow occurring, but will often lead to total blindness as early as age three and as late as age five.
Do kittens need taurine to grow?
Once they’re born, kittens still need a regular supply of taurine to maintain healthy bodyweights as they grow. For all cats, one of the main consequences of taurine deficiency is feline central retinal degeneration (FCRD).
What happens if taurine deficiency goes untreated?
"Clinical signs of taurine deficiency are slow to develop.". If caught early enough, dilated cardiomyopathy may be reversible with dietary supplementation. Left untreated for too long, retinal degeneration will lead to irreversible blindness, while dilated cardiomyopathy will progress to heart failure and death.
What happens if kittens are low in taurine?
The kittens themselves may be smaller, too, or can even suffer fetal abnormalities. Once they’re born, kittens still need a regular supply of taurine to maintain healthy bodyweights as they grow. For all cats, one of the main consequences of taurine deficiency is feline central retinal degeneration (FCRD).
What can you learn from a DNA kit for cats?
For instance, if your DNA kit tells you that your cat’s breed is prone to a genetic disease such as retinal degeneration, you will be able to speak to your veterinarian and understand the best way to either prevent this condition or manage it better. DNA kits for cats provide raw data regarding the wild cat index of your cat.
