Macular degeneration is the leading cause of severe vision loss in both the USA and in Europe.
This loss of vision may appear suddenly or it may progress slowly. Normally, the person's peripheral and color vision are unaffected. In exudative, the degeneration of the macula occurs with hemorrhaging or leaking of fluid from small blood vessels that develop beneath the center of the retina. Resulting in scarring and vision loss. Macular degeneration is probably the result of free radical damage similar to the type of damage that causes cataracts.
