Dear Daisy Dog
Sandy, my 10-year-old shep-collie, has cloudy eyes. My vet says he doesn’t have cataracts, and that there are no problems with Sandy’s eyes, but I’m not sure exactly what she did say was causing the cloudiness. Can you explain?
It sounds like Sandy has lenticular sclerosis, also called nuclear sclerosis, a normal aging change that I, too, have.
As our eyes age, the fluid in the center of each lens gets squeezed out, and the lens gets harder.
The lens is still clear, so light makes its way to the retina in the back of the eye in the normal way, but the denser lens reflects a blue-white haze back to our people when they look at us.
The name “sclerosis” refers to hardening of the lens (like in the word arteriosclerosis, hardening of the arteries.) The word “lenticular” refers to the lens, and “nuclear” refers specifically to the center of the lens, which gets the hardest.
This is not a medical problem, but it serves as a reminder that it’s time to watch for other aging changes that may present problems ... and to cherish every day with Sandy.
