dogs greater than seven years old. Nuclear sclerosis appears as a
bilateral bluish-grey haziness at the nucleus, or center of the lens,
caused by an increase in the refractive index of that part of the lens
due to its increased density. Other Names Nuclear Sclerosis
Causes Nuclear sclerosis is an age-related change in

animals. It is caused by compression of older lens fibers in the
nucleus by new fiber formation. The denser construction of the nucleus
causes it to scatter light.
Diagnosis It is often confused with cataracts. The
condition is differentiated from a cataract by its appearance and by
