Previous Next 4 of 5 The back of your eye

Structures at the back of your eye include the:

  • Retina. The retina is a thin layer of tissue that lines the back inner wall of your eyeball. It consists of millions of cells that capture the images focused onto them by your cornea and lens. When light hits these cells, electrical impulses are generated and carried to your optic nerve.
  • Macula. The macula is a specialized part of the retina located in the center of the back of the eye. This patch of densely packed light-sensitive cells is essential to your central vision and allows you to see fine detail.
  • Optic nerve. The optic nerve carries information gathered by your retina to your brain.
