When your dog ages, their eyes go through changes. One common and expected change for older dogs is a cloudy-looking lens. Naturally, many people assume this problem is a cataract. However, that is not always the case.
Lenticular sclerosis (also known as nuclear sclerosis) does not affect your dog's sight the same way as cataracts. However, it is a sign your dog's eyes may need extra attention. Keep reading to learn more about lenticular sclerosis and what to expect when your dog has this condition.
What Is Lenticular Sclerosis?
Lenticular sclerosis happens when fibers from the outer parts of the eye lenses begin to push on the thinner inner parts. The result is a thickening of the lens and an opaque, bluish appearance in the center of the pupil. Many dogs get lenticular sclerosis in both eyes. Most veterinarians consider this condition a normal part of aging.
How Does Lenticular Sclerosis Affect Dogs?
Fortunately, most dogs don't seem to have serious vision problems with lenticular sclerosis. They may experience some diminished vision, but not enough to affect their quality of life. Some dogs may have mild vision problems like trouble judging distances or diminished night vision. Lenticular sclerosis may compound other eye problems. The condition also does not seem to be painful or irritating to the dog.
How Is Lenticular Sclerosis Different From Cataracts?
Cataracts are a thickening of the lens that blocks out or diminishes the amount of light entering the eye. Your veterinarian checks for it with pupil dilation and special tools to look at the back of the eye. With lenticular sclerosis, light can still penetrate the lens and causes a normal light response. However, cataracts will nearly or completely block light from passing through the lens.
Does Lenticular Sclerosis Lead to Cataracts?
While many dogs with lenticular sclerosis may get cataracts, there does not seem to be a solid correlation between the two. Many dogs with lenticular sclerosis never develop cataracts and vice versa. However, have the veterinarian do a cataract check regularly if they have this condition.
Can You Treat Lenticular Sclerosis?
Unfortunately, you or your veterinarian cannot prevent or treat lenticular sclerosis. Like many other health problems, a good diet and exercise go a long way to maintaining your dog's quality of life. You can also change your dog's environment and routine to accommodate any possible vision changes.
If your dog has cloudy-looking eyes, don't assume it is lenticular sclerosis or a cataract. Bring your dog to a veterinarian for a diagnosis and to rule out serious eye health issues. All dogs need routine checkups to catch any problem early and maintain good health.
