All layers of the retina (200X)

This image shows all layers beautifully. Just to make some order of the mess, I've made a short list of all the layers starting from the outside of the eye (bottom of image) to the inside (top). I find it quite easy to get confused by all the names. That's why I made a list:

  1. Most peripherally lies the sclera which consists of fibroblasts, a few elastic fibers and bundles of collagen of which all run parallel to the surface of the eye.
  2. Choroid is the dark membrane above the sclera.
  3. Pigmented epithelial cells; dark and thin layer (not visible in this image).
  4. Stratum photosensorum or the receptor layer is a thin layer that stains lightly. This is the rods and cones.
  5. Outer nuclear layer holds the nuclei if the rod and cone cells.
  6. Outer plexiform layer is a synaptic layer.
  7. Inner nuclear layer holds Müller's cells and nuclei of bipolar nerve cells.
  8. Inner plexiform layer is a pure synaptic layer with synapses between the bipolar cells and the ganglon cells.
  9. Ganglion layer: gangon cells
  10. Optic fiber layer conists of Müller's fibers, including horizontal and vertical axons from ganglion cells (lightly stained layer).

In between the stratum photosensorium is a unknown layer of cells containing distinct nuclei.
