What is the difference between dry and wet AMD?
MD appears in 2 forms: dry and wet. Dry AMD is more common and may or may not develop into the wet form at any time. Dry AMD is characterized by yellowish fatty deposits called drusen that collect in the macula and can cause vision loss of different degrees. Serious vision loss caused by dry AMD is rare. Only about 10% to 20% of people with AMD have the wet type. Wet AMD strikes quickly, however, and can result in rapid vision loss. This type of AMD is characterized by abnormal, leaky blood vessels in the macula that may progress and create scar tissue, causing permanent blind spots. Though less common, wet AMD is responsible for up to 90% of severe vision loss.
