Questions: Question 8 Damage to the optic chiasm results in the complete loss to which part of your vision?

Damage to the optic chiasm results in the complete loss of peripheral vision in both eyes, a condition known as bitemporal hemianopia.

Explanation:

• The optic chiasm is the part of the brain where the optic nerves partially cross. It is located at the base of the brain, just above the pituitary gland.
• Each optic nerve carries visual information from the retina of each eye. At the optic chiasm, the nerve fibers from the nasal (inner) halves of each retina cross to the opposite side of the brain, while the fibers from the temporal (outer) halves remain on the same side.
• Damage to the optic chiasm typically affects the crossing fibers from the nasal halves of the retinas. Since these fibers are responsible for the peripheral vision of each eye, damage to the optic chiasm results in the loss of peripheral vision on both sides, leading to bitemporal hemianopia.

In summary, damage to the optic chiasm results in the loss of peripheral vision in both eyes.
