Among older individuals, macular degeneration is the top cause of blindness or vision loss. This degeneration refers to the tissues around the macula, which is the part of the retina that allows for sharp vision.
The dry version of macular degeneration is actually the early stage of the disease. Although its exact cause is not known, it is believed to be caused by age and the thinning of the macular lining.
Dry or non-neovascular macular degeneration is believed to be the early signs of macular degeneration in general. The dry version is caused by deposits and debris of the tissue surrounding the macula. These deposits, known as drusen, are seen as yellow spots in the retina. Drusen builds up and causes vision loss. Dry macular degeneration is the less severe version of the disease. There is no known treatment for the illness, but some vitamin studies have proven hopeful.
The more severe form of macular degeneration is the wet or neovascular. This type forms a new network of blood vessels behind the retina. Although this type is actually the body’s natural way of trying to repair the degeneration, it is not successful. The vessels leak blood and other fluids which causes irreparable damage to the cells of the retina. Fortunately only about 10% of people with dry macular degeneration actually progress to the more severe wet version.
The wet version also comes in two categories with one being less severe than the other. The occult version does not form as many vessels and less leakage occurs. The other category, though, causes severe damage to the vision. The classic category forms a multitude of new vessels that can be seen beneath the retina. The leakage of these vessels is also more pronounced. Thus the most severe damage is done with classic wet macular degeneration.
