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.
This article will discuss the three most common types of cataracts nuclear cortical and posterior subcapsular as well as other less common types including anterior subcapsular posterior polar traumatic congenital and polychromatic. While the majority of cataracts in the population are age related or senile cataracts there are many types and causes of cataract. This eventually becomes hard or sclerotic due to condensation on the lens nucleus and the deposition of brown pigment within the lens.
Nuclear sclerosis is the most common type of cataract and involves the central or nuclear part of the lens. The main types of age related cataracts are nuclear sclerosis cortical and posterior subcapsular. 10 any opacity in the lens or its capsule is a cataract except for nuclear sclerosis which is an aging change that results from compression of the oldest.
