The macular degeneration (AMD)

The macular degeneration (AMD) is a degradation of a portion of the retina (the macula), can lead to loss of central vision.

This multifactorial disease develops chronically and mainly affects people over 50 years.

The AMD can take two forms:

  • the atrophic or dry form is the most common. In this case, a issue of cell metabolism leads to a degeneration of retinal cells.
  • the exudative or wet form, is characterized by a proliferation of new blood vessels under the retina. The flow of serum by these vessels leads to a decreased visual acuity.
