Macular degeneration - focus The age-related macular degeneration (AMD, also named senile macular degeneration) is a degenerative disease of the macula lutea, central area of the retina, point where visual acuity is maximal and point on which acute vision of the details is made (represented in dark blue). This degenerescence mainly affects persons over 65 years old and lead to an important loss of the visual field. Juvenile forms of degeneration also exist (genetic diseases). AMD can take a dry form or, as here, a humid form (also named exsudative or neovascular). In this case, new choroidial blood vessels form (neovascularization) and invade the region located under the macula lutea ; retinal hemorrhages can occur as these new vessels are very fragile, leading to a destruction of the macula lutea and to cecity.
