Macular Degeneration
Age-related macular degeneration, often referred to as AMD, is a medical condition that usually affects older adults. This vision-stealing disease is the result of degeneration to the macula. It results in a loss of vision in the center of the visual field because of the damage to the retina. It occurs in dry and wet forms and is the leading cause of blindness and visual impairment in adults over the age of 50.

Wet AMD
This form is less common but much more serious. Wet AMD is when new, abnormal blood vessels grow under the retina. These vessels may leak blood or other fluids, causing scarring of the macula. You lose vision faster with wet AMD than with dry AMD. Many people don’t realize they have AMD until their vision is very blurry. This is why it is important to have regular visits to an ophthalmologist. They can look for early signs of AMD before you have any vision problems.
Dry AMD
This form is quite common. About 80% (8 out of 10) of people who have AMD have the dry form. Dry AMD is when parts of the macula get thinner with age and tiny clumps of protein called drusen grow. You slowly lose central vision. There is no way to treat dry AMD yet.
