Study Notes

Retinal Layers

  • The retinal pigment epithelium provides critical metabolic and supportive functions to photoreceptors.
  • The receptor layer contains the light-sensitive outer segments of photoreceptors.
  • The outer nuclear layer consists of photoreceptor cell bodies.
  • The outer plexiform layer is where photoreceptor, horizontal, and bipolar cells synapse.
  • The inner nuclear layer contains horizontal, bipolar, and amacrine cell bodies.
  • The inner plexiform layer is where bipolar, amacrine, and retinal ganglion cells synapse.
  • The retinal ganglion cell layer consists of retinal ganglion cell bodies.
  • The optic nerve layer contains ganglion cell axons traveling to the optic disc.
