AP2 M3 Exam page 2a.png
C, damage is in the right optic tract. Sensory info from the left side
travels simultaneously after the optic chasim to the brain's right
side.
C
The right optic tract is damaged. All the sensory
information from the left visual fields travels together

Right Optic nerve, becaause the entire eye is blind and information
has not been able to reach the optic chiasm that is further back in
the brain and receives information after the optic nerve.
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.
