Types of AMD

Dry and wet. The most common form of AMD is “dry” AMD. This is caused by the appearance of small yellow deposits called drusen, which form under the retina. These are accumulated waste products of the retina, which can grow in size and stop the flow of nutrients to the retina. This will cause the retinal cells in the macula that process light to die, causing vision to become blurred. This form of the disease usually worsens slowly. “Wet” AMD generally causes more rapid and more serious vision loss. In this form of the disease, tiny new blood vessels grow under and into the retina. These blood vessels are fragile and often break and leak, causing a loss of vision. 

Wet AMD

"Wet" AMD causes the most serious vision loss. In this form of the disease, tiny unhealthy blood vessels grow under the retina. These blood vessels often break and leak, causing loss of vision.
