The retinal pigment epithelium is the pigmented cell layer that lies just outside the neurosensory retina and nourishes retinal cells. It sits between the neural retina and the choroid, providing essential support to photoreceptors by phagocytosing shed outer segment discs, transporting nutrients, and recycling visual pigments. It also helps form the blood-retina barrier and absorbs excess light with its pigment. The other options don’t fit: the vitreous is the gel filling the eye, the optic nerve carries visual information to the brain, and accommodation refers to the lens adjusting shape for focusing.
