Macular Degeneration is an eye disease that occurs when the center of the retina or macula deteriorates. The retina helps eyes focus and allows people to read, recognize colors or faces, drive a car and see objects in detail. There are several risk factors and there are symptoms. Regular eye exams can help prevent the disease from rapidly declining even though there is no known cure.
Risk factors include age, smoking, genetics, and race. Most people experience the disease after the age of 55. Individuals who smoke are at a greater risk for the disease, too. People who have a family history of the disease are also at risk and individuals who are Caucasian can experience the disease more than people of Hispanic or African-American descent.
Symptoms include difficulty seeing in dim light, a partial loss of vision, and blurred vision. Sometimes straight lines appear wavy and this is one of the most characteristic signs of the disease.
The disease is broken down into two types. There is dry macular degeneration and wet macular degeneration. The dry form is diagnosed when drusen which are yellowish spots accumulate in the macula of the eye. These deposits form as the tissue deteriorates. Dry macular degeneration is not as severe as the wet type. You can get more details here about the macular disease.
Dry macular can progress slowly over years. The deterioration of the eye can become so bad that there is major vision loss. Wet macular degeneration lets new blood vessels grow under the retina and these can leak, harming the retina. This then leads to blind spots in the central vision.

While there is no known cure there are clinical trials being held to look for viable treatments. Regular eye exams can help detect the disease early enough that it can be treated so that the vision does not deteriorate as quickly.
