Age-Related Macular Degeneration (AMD)
Age-related macular degeneration affects 25 to 30 million people worldwide.
The macula is located in the centre of the retina, at the back of the eye. It processes the images our brain translates into central vision. The size of a pea, the macula helps to see sharp detail, such as a freckle on a nose.
AMD can seriously affect the central vision in just a few months or over the course of several years. It might be possible to spot a small coin on the floor but have difficulty reading the time on the clock on the wall.
While no two individuals with AMD experience exactly the same degree of vision loss, brighter light and sharp contrast in color can make objects more visible to anyone with the condition.
The cause and cure for AMD are unknown.
In the early stages your central vision may be blurred or distorted with things looking an unusual size or shape. This may happen quickly or develop over several months. You may be very sensitive to light or actually see lights that are not there. This may cause some discomfort occasionally but otherwise macular degeneration is not painful.
