Age-related macular degeneration (AMD)

There are 12 to 15 million patients suffering from AMD worldwide. In Europe and the United States, about 4 million patients are afflicted with AMD; more than 350,000 to 400,000 patients with AMD go blind every year.

As its name implies, AMD is related to the patient’s age. Patients suffering from this disorder start by losing central vision (responsible for precision, for example for reading) and progressively go blind at a later age, between 70 and 90.

There are two forms of AMD: 

Dry form: Most patients suffer from the dry form of the disease that generally causes localised
   atrophies of the central retina. There is no treatment for this form of AMD.

Wet form: Degeneration of photoreceptors is combined with the formation of new vessels and
   oedemas under the retina. These patients can be treated with drugs called anti-VEGF (vascular
   endothelial growth factor). These treatments delay the aggravation of the disease which
   nevertheless continues its course.
