Previous Next 6 of 7 The back of the eye

Structures at the back of the eye:

  • Retina. The retina is a thin layer of tissue that lines the back inner wall of the eye. It consists of millions of cells that capture the images focused onto them by the cornea and lens. When light hits these cells, electrical impulses are generated and carried to the 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 the central vision and allows you to see fine detail.
  • Optic nerve. The optic nerve carries information gathered by the retina to the brain.
