Thankfully it has been shown in scientifically controlled studies that one type of macular degeneration called age related macular degeneration or AMD can be successfully slowed and thereby treated with vitamins.  There have been two major studies that have corroborated the fact that the correct combination of anti oxidants and vitamins slow the progression of this horrible disease for many patients.  Many types of age related macular degeneration eye vitamins are on the market.  Some contain more than the ingredients that were used in the studies and thus might offer more anti oxidant power.
