Age-related macular degeneration (AMD) affects many people over the age of 50. AMD is the leading cause of blindness in the people over 65 years of age throughout the world. When AMD damages the macula (part of the retina), central vision is decreased.
There are two types of AMD, each with a distinct cause. Dry AMD, which makes up about 90% of cases, is caused by abnormal deposits under the macula which leads to cell breakdown. The less common Wet AMD is caused by abnormal blood vessel growth and breakage in the choroid, which supplies blood to the macula.
