Study Notes

Visual Pathway

  • The visual pathway includes retinoid axons from the eyes to the occipital visual cortex
  • The optic nerve moves to the optic chiasm, where some decussation is noted
  • 90% of fibers synapse in the thalamic component (lateral geniculate bodies)
  • 10% of fibers synapse in the midbrain
  • Axons from the LGB then project to the occipital lobe as the upper and lower fiber bundles

Field of Vision

  • The field of vision is the visual area seen by an eye at a given instant
  • It is the area of the external environment that can be seen by one eye (monocular)
  • The area seen to the nasal side is called the nasal field of vision
  • The area seen to the lateral side is called the temporal field of vision
  • Information from the right side of the visual field has the image falling on the left visual cortex
  • Information from the left side of the visual field has the image falling on the right visual cortex
