For the first time, researchers restored some vision to people with a common type of eye disease by using a prosthetic retinal implant. If approved for broader use in the future, the treatment could improve the lives of an estimated one million, mostly older, people in the United States who lose their vision to the condition. The patients’ blindness occurs when cells in the center of the retina start to die, what is known as geographic atrophy resulting from age-related macular degeneration. (Kolata, 10/20)

The syndrome, which was defined by the AHA for the first time in October 2023, reflects how these conditions can influence or worsen each other. (Moniuszko, 10/20)
