Feline Lenticular Sclerosis/Nuclear Sclerosis

Lenticular or Nuclear sclerosis is a transparent, blue cloudiness that develops on the eyes in older cats.

CAUSES:

This is one of the normal changes in aging cats. It develops at around 8 years old and becomes more obvious as they get older.

Although this looks similar to cataracts, it does not affect vision as much. If a cat with this condition is very old, they will have impaired vision.

SIGNS:

Lenticular sclerosis usually affects both eyes. Pupils will go from black to a gray cloudiness.

DIAGNOSIS:

Your veterinarian will perform a complete eye exam, usually dilating (expanding) the pupil to determine if your cat has lenticular sclerosis or a cataract.

A proper diagnosis is very important, because cataracts cause loss of vision, and require surgery.

TREATMENT:

Treatment is not necessary for this condition. However, if your cat is diagnosed with lenticular sclerosis, you should go to the veterinarian regularly to watch for cataracts. Cataracts can be removed with surgery, which is most effective if the cataract is caught early.

PREVENTION:

There is no way to prevent this condition. Almost every animal will have lenticular sclerosis as they age.

PROGNOSIS:

The prognosis is good as long as you bring your cat to your veterinarian regularly to check for cataracts.
