Age Changes in the macula (macular degeneration) implies the existence of pathological changes in the macula of the retina. It is the leading cause of vision loss in people over 60 years. There are two kinds of age-related macular degeneration, wet and dry, where the dryness is the most common.

Why age-related macular degeneration occurs is not clear, but the risk of developing the disease increases the older you get, and it is more common in women than in men. The macula is the area in the middle of the retina where we see as the sharpest. As you get older can change the macula, which means that you can get hard to see and above all to see sharply. Test if you have visual difficulties associated with the macula here.

Age Changes in the macula, the most common cause of severe vision loss in people over 60 years and it becomes more common with age. Approximately thirty percent of people aged over 70 have the disease in some form.

There are two forms of age changes in the macula – dry and wet. For the medical language is called the dry or wet AMD (Age-Related Degeneration Magular)

• The dry form is the most common, and affects approximately 85 percent. Visual impairment is often slow and rarely leads to severe visual impairment. Dry age-related macular degeneration means that the light-sensitive cells are broken down, and as the cells stop functioning you can see worse. The dry form can not be treated.

• The wet form affects approximately 10-15 percent. The sight deteriorate quickly, sometimes within weeks and may cause severe visual impairment. The reason for vision loss that is new, thin blood vessel formation in the macula. These blood vessels are fragile and leak blood and fluid under the macula, which makes it swell. Visual acuity in the middle of the vision deteriorates, while the outer field of vision is not affected as much. The wet form provides more difficult problems, but treatment with drugs can prevent vision gets worse and sometimes even improve it if it is detected in time.
