Breakthrough could protect the vision cells that let you see faces and colors

Scientists tested over 2,700 compounds on 20,000 human retinal organoids to find ways to protect cone photoreceptors, the vision cells responsible for seeing faces and colors that are destroyed in macular degeneration. The research identified several protective molecules and revealed that blocking casein kinase 1 can help cone cells survive longer under disease-like conditions. These findings were confirmed in mouse models and could lead to the first treatments to prevent central vision loss in millions of people.
