Age-related macular degeneration (AMD) is a problem with your central retina. It happens when a part of the retina called the macula is damaged. With AMD you can 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.
In early stages, AMD may have no symptoms at all. Symptoms that can appear as the disease progresses are distortion (bending) of straight lines, a decrease in the intensity or brightness of colors, blurred or distorted central vision or a gradual or sudden loss of center vision. Peripheral vision is usually not affected, and therefore complete visual impairment usually can be avoided.
