Question 6
pts
A patient is found to have blindness of the right visual field of both eyes. What part of the vision pathway
was most likely damaged? Explain your response.
A. Left optic nerve
B. Right optic nerve
C. Left LGN
D. Right LGNYour Answer:
Left optic nerve- This is because when the right and left optic nerve crosses the optic chiasm they go on
the opposite side of the brain meaning the left optic nerve controls right vision and right optic nerve
controls the left. after crossing the optic chiasm the vision pathway on the left is mostlikely damaged.
C
All the sensory information from the right visual fields travels together after the optic chiasm to
the left side of the brain.
Question 7
pts
A patient is found to have blindness in the right eye. What part of the vision pathway was most likely
damaged? Explain your response.
A. Optic chiasm
B. Occipital lobe
C. Left optic nerveD. Right optic nerve Your Answer:
D Right optic nerve. this is because the right optic nerve carries information from all aspects of the right
visual field. there is blindness in the right eye therefore it is the right optic nerve before crossing the
optic chiasm. if it was after cossing the optic chiasm there would not be complete blindness only deficits
in the left visual field.
D
Information from the right visual field has not yet crossed at the optic chiasm. Both peripheral
and nasal fields of the right eye would be missing.
