There are two types of macular degeneration. Name both types and describe each.

In the dry type of macular degeneration, the deterioration of the retina is associated with the formation of small yellow deposits, known as drusen, under the macula. This type leads to a thinning and drying out of the macula. The amount of central vision loss is directly related to the location and amount of retinal thinning caused by the drusen. There is no cure for the dry type of macular degeneration. In the wet type of macular degeneration, abnormal blood vessels (known as subretinal neovascularization) grow under the retina and macula. These new blood vessels may then bleed and leak fluid, thereby causing the macula to bulge or lift up, thus distorting or destroying central vision. Under these circumstances, vision loss may be rapid and severe. If vision is to be saved, immediate laser surgery should be done in the early stages of wet macular degeneration.
