OPTIC CHIASM

The optic chiasm is a part of the visual pathway. Key features:

  1. Location: Located at the base of the brain, above the pituitary gland.
  2. Function:
    • Nerve fibers from the nasal part of each retina cross over (decussate) here.
    • Allows for integration of visual information from both eyes.
  3. Importance:
    • Plays a crucial role in binocular vision and visual field processing.
    • Lesions or damage to the optic chiasm can cause specific visual field defects (like bitemporal hemianopia).

The optic chiasm is a key structure in the visual pathway.
