Age-related macular degeneration (ARMD)

A chronic retinal degenerative disease, sometimes associated with the development of neovessels under the macula. It causes the progressive loss of central vision while leaving peripheral (or lateral) vision intact. The loss of central vision is due to the degeneration of the photoreceptors, photosensitive cells (i.e. reacting to light) located in the macula. The degree of central vision loss varies according to the type of macular degeneration, its severity, and other individual characteristics. In Western countries, ARMD is the principal cause of severe vision loss in people over 50 years of age. Approximately 20 to 30 million individuals are currently affected and this figure could double in the next 35 years due to ageing of the population.
