Cataracts: Classification and Characteristics

 Cataracts are a common eye condition characterized by the clouding of the crystalline lens, which can cause a decrease in vision. In this article, we will discuss the different types of cataracts and their characteristics.

Nuclear Cataracts

Nuclear cataracts are the most common type of cataract and are caused by the clouding of the nucleus, or the center of the lens. These cataracts typically develop as a result of aging and are characterized by a yellow or brown color. Nuclear cataracts can cause a gradual loss of vision and can make it difficult to see in dim light.

Cortical Cataracts

Cortical cataracts form in the cortex, or the outer layer of the lens. They are characterized by white or gray opacities that form in a spoke-like pattern. Cortical cataracts can cause glare and halos around lights, and can make it difficult to see in bright light. They tend to develop as a result of long-term exposure to UV radiation, or due to certain medical conditions such as diabetes.

Posterior Subcapsular Cataracts

Posterior subcapsular cataracts form in the back of the lens, just beneath the capsule. They tend to develop rapidly and are characterized by a small, opaque area that can cause glare and halos around lights. These cataracts can make it

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
