Subcapsular cataracts develops under the capsule often at the back of the lens. A cortical cataract which tends to occur more in persons with diabetes begins at the outer portion of the lens then slowly moves inward. Nuclear cataracts occur in the center of the lens and may induce other eye problems such as myopia.
Cortical spoking cataract cs swelling of the cortex causing spoke wedge like peripheral cloudiness. Nuclear sclerotic cataract ns cloudiness of the nucleus the central portion of the lens. Cataracts types are defined by where the opacities exist within the lens and graded by how severe the opacities are at that location.
Nuclear cataracts were more connected with smoking. Also cortical and posterior subcapsular cataracts were related closely to environmental stresses including diabetes and drug ingestion. These usually manifest with blurred vision myopic shift and loss of blue yellow color perception.
Nuclear cataracts nuclear cataracts are the most common type. Congenital cataracts are a major cause of leukocoria in infants and can lead to vision loss and amblyopia if left untreated. The three most common types of cataracts in adults are nuclear cortical and posterior subcapsular cataracts.
The first signs of cortical cataract formation visible with the slit lamp biomicroscope are vacuoles and water clefts in the anterior or posterior cortex fig 5 3. Some cortical opacities remain unchanged for prolonged periods whereas others progress rapidly. Cortical cataracts vary greatly in their rate of progression.
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. Cataracts may be partial or complete stationary or progressive or hard or soft.

Nuclear cataract vs cortical cataract. There are three main types of age related cataracts. Nuclear sclerotic cortical and posterior subcapsular. Cataract is the clouding of the natural intraocular crystalline lens which focuses on. Cataracts that form earlier in life such as posterior subcapsular cataracts can progress more quickly than nuclear and cortical cataracts that are often age related.
Smoking poor nutrition obesity and drinking a lot of alcohol on a regular basis can increase the progression and risk factors for developing cataracts. Also called a nuclear sclerotic cataract this is the kind doctors see most. Anyone who lives long enough usually ends up with one. These take shape on.
This is referred to as a nuclear sclerotic cataract or a senile cataract. It develops slowly after age 50 60 and may never have to be removed. A cortical cataract is a clouding usually on the front of the lens and may cause signficant glare. It may develop more quickly.
