As we age, our eyesight tends to weaken. There are many reasons for this, but one of the most common is age related macular degeneration (AMD). This is a condition that can affect anyone, and can cause severe vision loss if not treated. It is important to know what causes it so that you can take steps to prevent further deterioration of your eyesight.
What Is Age Related Macular Degeneration?
AMD is a disease of the macula, which is the small part of the retina at the back of the eye that allows us to see objects clearly. The macula is responsible for sharp, clear images and color perception.
AMD begins when a small number of cells in the macula die or become damaged. These cells produce an enzyme called pigment epithelium-derived factor (PEDF), which helps keep the macula healthy. When these cells die or become damaged, PEDF production decreases, causing the macula to degenerate.
As the macula degenerates, the central vision is affected first. You may notice that you cannot see objects clearly. You will also experience problems with your night vision and color perception.
How Is AMD Diagnosed?
There are several ways to diagnose AMD. One of the easiest ways is by looking at the back of your eye. If you have AMD, there will be some kind of discoloration in the back of your eye. Another way is to use an ophthalmoscope. This is a special instrument that allows doctors to examine the back of your eye.
How Can I Prevent AMD?
There are many things that you can do to help prevent AMD. You should avoid smoking, and get regular check ups from your eye doctor. In addition, you should eat foods that are high in antioxidants, such as blueberries, strawberries, raspberries, spinach, and broccoli.
If you have AMD, there are some natural treatments that can help. You can try vitamin E supplements, or fish oil supplements. However, if you are already taking prescription medication, talk to your doctor before trying any other natural treatments.
