Macular Degeneration

Macular Degeneration is a problem in the part of the eye that controls your sharpest central vision. It is a group of diseases that result in a loss of detailed vision. The brain will not just leave the spot empty, so it learns to fill it in with spotty macular cell damage. People most of the time don't tell their doctors (opthalmologists) about it until it is well in advance.
There are two types of Macular Degeneration. Juvenile Macular Degeneration affects the central vision in young children. This takes place in the macula, or the central region of the retina. The retina is where we are able to read and to distinguish colors. The main symptoms

Wet Macular Degeneration causes more severe loss of vision. Dry Macular Degeneration is the age-related type. There is no proven cure for dry Macular Degeneration.
Basically what my research is stating is that there is a major genetic component that contributes to this disease. There are three general types of hereditary Macular Degeneration. The first is called early onset. This is when you get it when you are four years of age up to seven. In this type both parents and their children can be affected. This means it is dominantly inherited. Most of the time this is called Best Disease or Viteliform Macular Degeneration.
The second type is called middle onset. This is from five years of age up to twenty years of age. This type is called Stargarett's disease. This is the Juvenile Macular Degeneration. This type is recessively inherited. Meaning that this type can appear even if only a couple family members have it.
The third type is called late onset. This is when you get it in your thirties or forties. This type may have dominant or recessive inheritance.
Really the cause of Macular Degeneration is unknown. Recently researchers have discovered that a group of genes called ABCR contribute to the disease. When someone has these genes the likeliness of this person to form Macular Degeneration increases by 30 percent. In most situations Macular Degeneration is
