What Is AMD?
Age-related macular degeneration (AMD) is the deterioration of light-sensitive tissue at the center of the retina, called the macula; it is a major cause of blindness worldwide and is the leading cause of vision loss and blindness for Americans aged 65 years and older.1-4 By 2050, the estimated number of people with AMD is expected to more than double from 2.07 million (in 2010) to 5.44 million.5
AMD causes damage to the macula, the part of the eye needed for sharp, central vision that allows us to view objects that are straight ahead.1 The exact cause of AMD is unknown but is understood to develop as the eye ages.1 For some, AMD progresses slowly and vision loss does not occur quickly; but for others, the disease progresses faster and may lead to a loss of vision in one or both eyes.2 In fact, many people do not realize they have AMD until they experience blurred vision.6 Blurriness or waviness in the center of vision are common symptoms, and over time the blurred area may grow larger or blank spots may develop.1-3 Objects also may not appear to be as bright as they used to be, and adapting to dark environments may be more difficult.2,3 The changes in vision associated with AMD can interfere with everyday simple activities, such as the ability to see faces, drive, read, write, watch television, or even use the computer or phone.2,4 See Figure below for an example of how AMD may affect vision.
