/.A patient had a CVA in the area indicated by the red x in the figure, below. What type
of blindness is the patient most likely to incur? Explain your reasoning. - Answer-
✅Bilateral left visual field blindness.
The right optic tract is damaged. All the sensory information from the left visual fields
travels together after the optic chiasm to the right side of the brain.
/.A patient has a brain tumor in the area indicated by the red x in the figure, below. What
type of blindness is the patient most likely to incur? Explain your reasoning. - Answer-
✅Left eye blindness because there is damage to the left optic nerve. Information from
the left visual field has not yet crossed at the optic chiasm. Both peripheral and nasal
fields of the left eye would be missing.
/.True or False: All sensory information from the optic nerves cross at the optic chiasm. -
Answer-✅F
/.The ________ is controlled by the trochlear nerve. - Answer-✅Superior oblique
/.Your elderly patient is discussing her vision problems. She describes her vision as
blurry. Following a visual examination, her left eye deviates medially when looking
straight ahead. What is most likely causing the vision problem? Explain your reasoning.
- Answer-✅The abducens nerve controls the lateral rectus. Damage to the lateral rectus
would cause there to be a muscle imbalance, and the medial rectus would pull the eye
medially when looking straight ahead, causing blurry vision.
