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.
AMD is a condition that occurs when cells in the macula degenerate. Dry AMD is a main type of AMD, In this type the cells in the RPE of the macula gradually become thin and degenerate. This layer of cells is crucial for the function of the rods and cones which then also degenerate and die. Typically, dry AMD is a very gradual process as the number of cells affected increases. It usually takes several years for vision to become seriously affected. It causes a gradual loss of central vision, central vision is needed for derailed work and for thing like reading and driving.
Dry macular degeneration is a chronic eye disease that causes vision loss in the center of your field of vision. Dry macular degeneration is marked by deterioration of the macula (MAK-u-luh), which is in the center of the retina. The layer of tissue on the inside back wall of your eyeball.Dry macular degeneration is the more common form of the disease.Dry macular degeneration may worsen your quality of life by causing blurred central vision or a blind spot in your central vision. You need clear central vision for many tasks, such as reading, driving and recognizing faces.
