Final answer:
Drusen are small deposits that accumulate in the retina and are commonly associated with age-related macular degeneration (AMD). While drusen themselves do not directly affect peripheral vision, the progression of AMD can lead to the loss of peripheral vision.
Step-by-step explanation:
Drusen are small deposits that accumulate in the retina, specifically in a layer called Bruch's membrane. They are commonly associated with age-related macular degeneration (AMD), which affects the macula, the part of the retina responsible for sharp central vision. While drusen themselves do not directly affect peripheral vision, the progression of AMD can lead to the loss of peripheral vision.
