Lenticular sclerosis is associated with which of the following?

Lenticular sclerosis, also known as nuclear sclerosis, is primarily an age-related change seen in dogs. As dogs age, the lens of the eye can develop a progressive hardening and opacification, leading to a bluish or cloudy appearance. This condition is commonly observed in older dogs and occurs as a normal part of the aging process rather than as a result of any genetic defect, environmental exposure, or infectious disease.

The change is typically benign and does not usually affect vision significantly, although it can be confused with cataracts, which are a pathological condition. Understanding that lenticular sclerosis is a natural and expected phenomenon in older dogs helps to distinguish it from other eye conditions that may require intervention or treatment.
