Macular degeneration is a slowly progressing disorder of the retina, which results in loss of central vision and is found primarily in older adults in their sixties and seventies. It is the most common cause of visual impairment in adults aged over 50 years. Macular degeneration causes damage to the macula, a small central region of the retina responsible for sharp, detailed vision. The photoreceptors in the macula convert light signals into electrical impulses that are sent to the brain. When the photoreceptors start to degenerate, central vision becomes compromised, and daily activities, such as reading, driving, and recognizing faces, become difficult.
