Dry AMD is the more common form of Macular Degeneration. It is also referred to as atrophic, nonexcudative, or drusenoid form. This form accounts for 90 percent of Age-related Macular Degenerations. Dry AMD is characterised by the build-up of drusen, small yellowish deposits, beneath the macula. The layer of photo receptor cells in the macula begin to atrophy, or die, as some of the cells break down. These changes, may, in turn, result in a distortion of vision that is most apparent when reading. Often if one eye has dry AMD, the other eye will also show some signs of the condition. However, dry AMD does not usually cause total loss of reading vision.
