"Nuclear sclerosis" refers to a normal aging change in the eyes where the lens becomes harder and yellowish. It can cause blurry or cloudy vision, making things appear less clear.
Full definition
Just as for middle - aged people who need reading glasses, a dog
with nuclear sclerosis will not be able to see well up close.

Cataracts in dogs should be differentiated from nuclear density /
nuclear sclerosis in older animals, where the lens appears to be smoothly darkened and gray in color, but not clouding.
Nuclear sclerosis results in a cloudy appearance to the lens of the eye but is less harmful than cataracts because it does not greatly affect the vision of your pet.
Nuclear sclerosis develops in the lens, which serves as the part of the eye that takes outside light and transmits it onto the retina.

When an ophthalmoscope is used to examine an eye affected
with nuclear sclerosis, the back of the eye, the retina, can be clearly seen.
However, veterinary ophthalmologists can tell the difference
between nuclear sclerosis and cataract, using specialized equipment and their expertise.
While dogs may certainly develop cataracts, they much more commonly develop a condition called
nuclear sclerosis, sometimes called lenticlular sclerosis.
While cataracts and
nuclear sclerosis both have an effect on vision, the effect of cataracts is dramatic while that of nuclear sclerosis is less significant.
Cataracts and
Nuclear Sclerosis (an age - related change) are common in older pets, and can generally be observed easily with a hand - held ophthalmoscope.
This normal change, called
nuclear sclerosis, results in less flexibility of the lens, a hazy appearance, and less ability to focus on close objects.
A veterinarian can differentiate whether the cloudiness of the eye of a companion animal is
nuclear sclerosis or cataracts by a thorough eye examination with the pupil fully dilated.
With age, it begins a hardening process called
nuclear sclerosis that describes the way fibers, which create the lens, are aligned.
Nuclear sclerosis has no required treatment because it does not greatly impair the vision of the companion animal and is a natural occurrence.
Nuclear sclerosis, as described, can mimic the appearance of a cataract, yet the eye with this condition can see and is not diseased.
The lenses with
nuclear sclerosis may look cloudy but they are still clear and the dog can still see through them; these are not cataracts.
Also keep in mind that dogs can develop
BOTH nuclear sclerosis AND cataract — many geriatric dogs do develop cataracts.
Others may or may not be hereditary, as with
nuclear sclerosis — the classic «old age» cataract.
Old age cataracts (
nuclear sclerosis) will pass.
A much more common problem in older pets is called
nuclear sclerosis.
Most cataracts develop with age, but shouldn't be confused with
nuclear sclerosis, a normal change of the lens in pets over 7 years of age, which causes the lens to appear somewhat whiter or grayer but does not seem to impair the dog's vision.
As dogs age, a natural bluish - grey cloudiness develops in the lens of the eye called
Nuclear Sclerosis.
Cloudy eyes are common in many older dogs, but they can also be a sign that your pup has a corneal ulcer,
nuclear sclerosis, an abrasion or, the most common sight impairment in older dogs, cataracts.
The most common change is
nuclear sclerosis, a hardening of the central portion of the lens that results in a clouding of the lens.
Nuclear sclerosis is a very common eye defect in older animals and is commonly mistaken for cataracts in companion animals.
Often confused with cataracts is a condition called
nuclear sclerosis.
Nuclear sclerosis is a normal aging change of the lens.
A:
Nuclear sclerosis, or hardening of the lens as a dog ages, is a normal aging change in any dog over the age of six.
Nuclear Sclerosis is easily mistaken as a Cataract, which is a different problem that also causes the lens to become cloudy.
While a cataract is an abnormality that can cause blindness and inflammation inside the eye,
nuclear sclerosis is normal for an older dog, and the condition has minimal effect on vision.
The cloudiness is normal aging of the lens, called
nuclear sclerosis.
Many older dogs develop a common lens opacity called
nuclear sclerosis, where the lens thickens and then will appear slightly more white.
If you are unsure if your pet has
nuclear sclerosis or not, take a flashlight and shine it into the center of one eye.
If you do not see any cloudy white spot in the center of the lens then your pet probably does not have
any nuclear sclerosis present.
The doctor word for this is
nuclear sclerosis and should not be confused with the pathological condition called cataracts.
