A 2×2 millimeter wireless retinal implant system helped many people with advanced geographic atrophy due to age-related macular degeneration regain functional central vision in a multicenter European study, according to results published in The New England Journal of Medicine.
Scientists at the SUNY College of Optometry propose that the rapid rise in nearsightedness, or myopia, stems not just from screen time but from prolonged close-up focusing in dim indoor lighting. This combination reduces light reaching the retina, potentially triggering eye changes. The study, set for publication in Cell Reports, offers a unified explanation for various myopia causes and treatments.

Scientists at the University of Southern California are starting a phase 2b clinical trial to test a microscopic stem cell implant aimed at restoring vision in patients with advanced dry age-related macular degeneration. The hair-thin patch seeks to replace damaged retinal cells, building on earlier research that showed safety and vision gains in some participants. Researchers hope it could offer a way to reverse vision loss where current treatments fall short.
