Macular degeneration is a leading cause of vision loss, affecting millions worldwide. Understanding its causes, recognizing early symptoms, and exploring available treatments are crucial steps in protecting your eyesight and maintaining a high quality of life.
What Is Macular Degeneration?
Age-related macular degeneration (AMD) is a progressive eye disease that affects the macula, the central part of the retina responsible for sharp central vision. AMD is the leading cause of sight loss in older adults, and it is estimated that 20 million people in the United States have AMD.1
AMD occurs when the macula becomes damaged, causing a loss of central vision. This can make it difficult to read, drive, and recognize faces. AMD is a chronic condition, but there are treatments that can help to slow the progression of the disease and preserve vision.
Types of Macular Degeneration
Macular degeneration is primarily categorized into two types: dry (atrophic) and wet (neovascular) macular degeneration. Dry macular degeneration is the more common form. It occurs when the macula, the central part of the retina responsible for sharp vision, thins and deteriorates with age. Over time, this can lead to gradual vision loss, particularly in the central field of view.
Wet macular degeneration is less common but more severe. It involves the growth of abnormal blood vessels beneath the retina, which can leak fluid or blood, causing rapid damage to the macula. This type can lead to sudden and significant vision loss. Early detection and treatment are crucial for managing both types and preserving as much vision as possible. Understanding the differences between these types helps in recognizing symptoms and seeking appropriate care.
Treatment Options For AMD
While there is no cure, there are a number of treatment options available for AMD, depending on the type and severity of the disease.2 Treatment options for dry AMD include lifestyle modifications, such as quitting smoking, eating a healthy diet, and exercising regularly. There are also a number of medications that can be used to treat dry AMD, such as antioxidant supplements and anti-VEGF injections.
Treatment options for wet AMD include anti-VEGF injections, laser therapy, and photodynamic therapy. Anti-VEGF injections are the most common treatment for wet AMD, and they work by blocking the growth of abnormal blood vessels under the macula. Laser therapy is used to destroy abnormal blood vessels, and photodynamic therapy is used to activate a light-sensitive drug that kills abnormal blood vessels.

AMD is a leading cause of sight loss in older adults, but there are a number of treatments that can help to slow the progression of the disease and preserve vision. If you are experiencing any symptoms of AMD, it is important to see an eye doctor right away. Early diagnosis and treatment can help to prevent serious vision loss.
There are a number of resources available online to learn more about AMD. The National Eye Institute (NEI) website has a wealth of information on AMD, including symptoms, risk factors, and treatment options. The American Macular Degeneration Foundation (AMDF) is another helpful resource for information on AMD. You can also find support groups and other reputable resources to help you cope with AMD.
