Age-related macular degeneration is a degenerative disease of the macula that causes a progressive decrease in central vision. The macula is a small area located in the center of the retina responsible for the central vision of fine details. This condition is one of the main causes of blindness in older adults in developed countries. This was explained by Dr. Denisse del Carmen Álvarez, First Degree specialist in Ophthalmology and Comprehensive General Medicine, from the Manuel Ascunce University Hospital in this city.
