In macular degeneration, the center of your retina begins to deteriorate. This causes symptoms such as blurred central vision or a blind spot in the center of the visual field. There are two types — wet macular degeneration and dry macular degeneration. Many people will first have the dry form, which can progress to the wet form in one or both eyes.

Two Types of AMD
This form is quite common. About 80% (8 out of 10) of people who have AMD have the dry form. Dry AMD is when parts of the macula get thinner with age and tiny clumps of protein called drusen grow. You slowly lose central vision. There is no way to treat dry AMD yet.
This form is less common but much more serious. Wet AMD is when new, abnormal blood vessels grow under the retina. These vessels may leak blood or other fluids, causing scarring of the macula. You lose vision faster with wet AMD than with dry AMD.
Many people don’t realize they have AMD until their vision is very blurry. This is why it is important to have regular visits to an ophthalmologist. They can look for early signs of AMD before you have any vision problems.
With AMD you lose your central vision. You cannot see fine details, whether you are looking at something close or far. But your peripheral (side) vision will still be normal. For instance, imagine you are looking at a clock with hands. With AMD, you might see the clock’s numbers but not the hands.
AMD is very common. It is a leading cause of vision loss in people 50 years or older. Risk factors for AMD include being 50 and older, smoking, having high blood pressure and eating a diet high in saturated fat. Although there is no cure for AMD, there are treatment options that may prevent or slow the progression of the disease.
