Macular Degeneration Types
There are two different kinds of macular degeneration. The "wet" type occurs when abnormal blood vessels start to grow under the macula. One of the earliest symptoms is straight lines appearing wavy.
The "dry" type of macular degeneration occurs when the light-sensitive cells in the macula start to break down. The most common symptom is blurry vision, particularly in the center of your visual field.
Both macular degeneration types are associated with aging. In addition, the dry form can turn into the wet form, but this is not always the case. About 90 percent of people diagnosed with this condition have the dry type, while 10 percent have the wet type.
