The retina is a thin layer of neural tissue at the back of the eye that detects light and converts it into signals, sent to the brain. During development, all the specialized neurons in the retina—including photoreceptors and other cells essential for vision—arise from stem-like cells known as retinal progenitor cells (RPCs).
