The human retina—the light-sensitive part of the brain situated in the back of the eye—is a feat of engineering at the heart of a critical sense: Sight. So diseases of the retina like retina pigmentosa or age-related macular degeneration, which lead to impaired vision and blindness, can be particularly intractable and devastating.
But scientists are zeroing in on a suite of strategies that may offer a ray of hope.
