Medical Definition of Macular degeneration. Macular degeneration: An eye disease that progressively destroys the macula, the central portion of the retina, impairing central vision. Macular degeneration rarely causes total blindness because only the center of vision is affected.
From Wikipedia, the free encyclopedia. Macular degeneration, often age-related macular degeneration (AMD or ARMD), is a medical condition that usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina. It occurs in dry and wet forms. Hypertension (high blood pressure) Individuals with high blood pressure are more likely to be affected by age-related macular degeneration. 2  This is because high blood pressure, like smoking, leads to a constriction, or narrowing, of the blood vessels in the choroid which gives blood and oxygen to the retina.
