Age Related Macular Degeneration

 Age-related macular degeneration (AMD) is a medical condition that affects the retina, the light-sensitive layer of tissue at the back of the eye. It is a leading cause of vision loss in people over the age of 50, and it is especially common in older adults.

AMD occurs when the cells in the macula, a small area at the center of the retina, become damaged or die. The macula is responsible for producing clear, sharp central vision, and when it is damaged, it can cause problems with reading, driving, and other activities that require fine visual detail.

There are two main types of AMD: dry AMD and wet AMD. Dry AMD is the more common form, and it occurs when the cells in the macula become thin and dry. This can cause a gradual loss of central vision over time. Wet AMD is less common, but it is more severe. It occurs when abnormal blood vessels grow under the retina and leak blood or fluid, causing scarring and rapid vision loss.

The exact cause of AMD is not fully understood, but there are several risk factors that have been identified. These include age, genetics, smoking, high blood pressure, high cholesterol, and a diet high in saturated fats. People with light-colored eyes and those who have been exposed to sunlight for long periods of time may also be at higher risk for developing AMD.

There is no cure for AMD, and vision loss due to the condition is generally irreversible. However, there are treatments available that can help to slow the progression of the disease and improve vision.

For people with dry AMD, treatment may involve taking vitamin and mineral supplements, such as the Age-Related Eye Disease Study (AREDS) formula, which contains high levels of vitamin C, vitamin E, and zinc. This treatment has been shown to slow the progression of the disease and reduce the risk of developing advanced AMD.

For people with wet AMD, treatment may involve injections of medications into the eye to stop the growth of abnormal blood vessels and prevent further vision loss. Other treatments, such as photodynamic therapy and laser surgery, may also be used to treat wet AMD.

In addition to medical treatment, there are also several lifestyle changes that can help to reduce the risk of developing AMD or slow its progression. These include quitting smoking, eating a healthy diet rich in fruits, vegetables, and omega-3 fatty acids, and wearing sunglasses and a hat to protect the eyes from sunlight.

It is important for people at risk for AMD to have regular eye exams to monitor the condition and catch any changes early. Early detection and treatment of AMD can help to preserve vision and improve the chances of maintaining good vision over time.

In conclusion, AMD is a common condition that affects the retina and can cause vision loss in older adults. While there is no cure, there are treatments available that can slow the progression of the disease and improve vision. By taking steps to reduce the risk of developing AMD and receiving regular eye exams, people can take control of their eye health and preserve their vision as they age.

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...
