Age-related macular degeneration (AMD) is a progressive eye disease that affects the macula, the central part of the retina responsible for sharp, detailed vision. AMD is the leading cause of permanent visual impairment in older adults, and it typically manifests as a gradual loss of the ability to distinguish fine details, such as faces or print. Other symptoms of AMD include distorted or blurry vision, straight lines appearing wavy, and dark or empty spots in the central field of vision. Presbyopia is a normal age-related condition that causes difficulty focusing on close objects, while night blindness and glaucoma are other eye conditions that can cause vision loss but are not typically associated with the loss of fine details.
