Because the nucleus increases in size as the animal ages the sclerosis is more apparent in older animals and may be mistaken as a senile cataract. Nuclear sclerosis is an apparent opacification of the lens caused by the compression of older lens fibers in the center of the lens nucleus as a consequence of the production of new fibers. It wiil in time lead to cataract formation.
This is a natural aging process. This is a natural aging process. This term means hardening of the center of the lens.
All animals including humans with a natural anatomic lens can develop nuclear cataracts and its related symptoms as they age. Nuclear sclerotic cataracts become a problem when it becomes severe or symptomatic. Nuclear sclerosis is the clouding of the lens of the eye.
Nuclear sclerosis is very common in humans. Nuclear sclerosis refers to cloudiness hardening and yellowing of the central region of the lens in the eye called the nucleus. When grading judge the color as well as best corrected.
May be asymmetric. May induce a myopic shift. When pronounced an oil droplet effect may be seen with distal direct ophthalmoscopy.
It s development is marked by anterior nuclear relief. Instead the change is in the nucleus. It is not posterior yellowing.
In an early cataract you will see that the central nucleus is actually more clear than the anterior and posterior embryonic layers of the lens.
Nuclear sclerosis grading scale. In 2002 the who published a simplified cataract grading scale. These images are directly from that paper. Nuclear sclerotic ns best graded with slit beam at 30 to 45 degree angle to the cataract.
