◉ the posterior portion of the outer fibrous layer of the eye is called
the ____ Answer: sclera
◉ what portion of the eye supplies blood supply to the outer layers
of the eye? Answer: choroid (of the middle layer)
◉ true or false: the more numerous type of photoreceptors are rods
Answer: true
◉ what is the correct order of how light passes through the eye?
Answer: cornea, lens, vitreous fluid, retina
◉ 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.
◉ Match the numbers (1-5) in the figure below with the correct
terms (A-H).
Note: not all terms will be used.
