What causes macular degeneration?

Due to aging, deposition of lipid, often appear small white or yellow, build up under the retina at the back of the eye. These spot can prevent the cells in the retina from getting enough oxygen or nutrients. When this occurs, the light-sensing cells can then become damaged, which can lead the degeneration of the macula – often called dry macular degeneration.

Another type is wet macular degeneration. This type is not as common as dry macular degeneration, but it accounts for about 10% of cases. This occurs when abnormal blood vessels grow behind the macular, leaking blood and fluid, causing scaring on the macula.

Juvenile forms of macular degeneration are all inherited. They are congenital meaning they are passed down genetically and progressive meaning it gets worse over time.
