To date, there is no medical treatment to reverse this process. One common age-related vision problem is nuclear sclerosis, in which the lens of a dog's eye becomes whitish and cloudy. The appearance of a milky lens can cause great concern to many dog owners. Often this age-related condition is mistaken for cataracts. Nuclear sclerosis does not create serious vision problems except for an inability to clearly see nearby object, along with decreased vision in low-light conditions.
Cataracts are another age-related problem.
In both humans and dogs, cataracts can create serious sight deficiencies or, in advanced cases, even blindness. They may be treated surgically. Another canine vision problem is glaucoma, an increase in pressure within the eye. In many cases, glaucoma and cataracts appear together. If you detect any changes in the appearance of your dog's eyes, contact your veterinarian.
