The posterior portion of the outer fibrous layer of the eye is
called the _____.
Sclera
What portion of the eye supplies blood supply to the other layers
of the eye?
Choroid (of the middle layer)
True or false: The more numerous type of photoreceptors are
rods.
True
What is the correct order of how light passes through the eye?
A. Cornea, Lens, pupil, retina
B. Cornea, lens, vitreous fluid, retina
C. Lens, retina, cornea, optic nerve
D. Lens, vitreous fluid, optic nerve, retina
B. Cornea, lens, vitreous fluid, retina Vitreous fluid fills the space
posterior to the lens
(Vitreous fluid fills the space posterior to the lens)
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.
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.
Left eye blindness
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.
False
(only medial fibers cross at optic chiasm)
The ________ is controlled by the trochlear nerve.
A. Superior rectus
B. Medial rectus
C. Lateral rectus
D. Superior oblique
D. 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.
A. Cataracts
B. Abducens nerve damage
C. Brain tumor in the occipital lobe
D. Medial rectus damageE. Superior rectus damage
B
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. (Diplopia)
