Question 1

A hereditary condition with partial or total absence of pigment in the eye.
A)glaucoma
B)optic nerve atrophy
C)albinism
D)cataracts

Accepted Answer

Albinism is a hereditary condition characterized by partial or total absence of pigment in the skin, eyes, and hair. This can lead to vision problems, such as reduced visual acuity, strabismus, and nystagmus, due to the abnormal development of the retina and optic nerve. Glaucoma is a progressive eye disease that damages the optic nerve and results in visual field loss, often associated with increased intraocular pressure. Optic nerve atrophy refers to the degeneration or loss of the optic nerve fibers, leading to vision impairment or blindness in severe cases. Cataracts are a clouding of the eye's natural lens, causing blurred vision and glare, and are often due to aging or injury.

Question 2

Teachers working with students who are visually impaired should practice each of the following EXCEPT
A)feel comfortable using vision words such as look,see,and watch
B)use the pupil's name when addressing a student
C)be fearful of touching a student who is visually impaired
D)encourage independence

Accepted Answer

Teachers should not be afraid of touching a student who is visually impaired as physical gesture can help in communication and understanding. Teachers should also practice using vision words comfortably, use pupil names, and encourage independence in visually impaired students.

Question 3

______ is a term that describes people who cannot see well even with correction.
A)Visual acuity
B)Functionally blind
C)Visual impairment
D)Field loss

Accepted Answer

Visual impairment is the correct term to describe people who have difficulty seeing, even with corrective measures such as glasses or contact lenses. This can include complete blindness or partial vision loss. Visual acuity refers to the sharpness of vision, while functionally blind and field loss are specific types of visual impairment.

Question 4

The colored,circular part of the eye in front of the lens that controls the size of the pupil.
A)cornea
B)iris
C)retina
D)macula

Accepted Answer

The iris is the colored, circular part of the eye in front of the lens that controls the size of the pupil. The cornea is the clear, outermost layer of the eye. The retina is the layer of tissue at the back of the eye that is responsible for converting light into nerve impulses. The macula is a small, specialized, central area of the retina responsible for sharp, detailed vision.

Question 5

A student's field loss is related to the
A)ability to perceive details.
B)ability to see materials presented closely.
C)amount of vision in quadrant regions.
D)ability to discriminate color.

Accepted Answer

A student's field loss is related to the amount of vision in quadrant regions. Field loss refers to the loss of part of a person's visual field. This can occur in different regions or quadrants of the visual field. Therefore, the amount of vision in quadrant regions is related to a person's field loss. Choices A, B, and D are not related to field loss but refer to other aspects of visual perception such as the ability to perceive details, see materials presented closely, and discriminate color.

Question 6

The amount of vision in the quadrant regions to the right,left,up,and down while gazing straight ahead.
A)visual field
B)visual acuity
C)field loss
D)legally blind

Accepted Answer

Visual field refers to the entire area that can be seen when looking straight ahead, including the quadrant regions to the right, left, up, and down. Visual acuity refers to the sharpness and clarity of vision, and is not relevant to this specific question. Field loss refers to a reduction in the visual field due to injury, disease, or other factors, which is also not the answer to this question. Legally blind refers to a level of severe visual impairment that meets certain legal criteria, and is not specifically related to the quadrant regions of vision.

Question 7

Which is considered a difference between individuals labeled as being functionally blind and blind?
A)The use of light perception
B)The need for orientation and mobility training
C)The use of low vision to gain information from the environment
D)The use of Braille

Accepted Answer

Functionally blind individuals may use their limited vision to gain information from the environment, whereas blind individuals rely more on non-visual means.

Question 8

Light enters the eye first through the
A)retina.
B)iris.
C)cornea.
D)macula.

Accepted Answer

Light enters the eye first through the cornea, which is the clear outer layer that covers the front of the eye and helps to focus incoming light.

Question 9

The vitreous humor
A)the transparent outer portion of the eyeball that transmits light to the retina.
B)the inner layer of the eye containing light-sensitive cells that connect with the brain through the optic nerve
C)a colorless mass of soft,gelatin-like material that fills the eyball behind the lens
D)the area of best central vision located in the retina.

Accepted Answer

The vitreous humor is a colorless mass of soft, gelatin-like material that fills the eyeball behind the lens.

Question 10

Learning to hold a cereal box within one's field of vision to read the price would an example of using ______.
A)residual vision
B)field vision
C)reduction strategies
D)magnification

Accepted Answer

Residual vision refers to the remaining vision a person has after experiencing vision loss. In this scenario, the person is learning to use their residual vision to read the price on a cereal box within their field of vision.

Question 11

Which visual acuity is considered to be legally blind?
A)20/200 or less in the better eye with correction
B)20/200 or more in the worse eye with correction
C)20/200 or less in the better eye without correction
D)20/100 or less in either eye with correction

Accepted Answer

Legally blind is defined as having a visual acuity of 20/200 or less in the better eye with the best possible correction.

Question 12

Myopia is a condition that occurs when
A)an eyeball is longer than normal from front to back allowing rays of light to focus in front of the retina instead of on the retina
B)the eyeball is too short and the image focuses behind the retina
C)an individual is farsighted
D)one or more surfaces of the cornea or lens are cylindrical,not spherical

Accepted Answer

Myopia is also known as nearsightedness, which means that a person can see objects clearly that are close to them but struggle to see objects clearly that are far away. This is caused by the eyeball being longer than normal from front to back, causing the light to focus in front of the retina instead of on the retina.

Question 13

The ability to visually distinguish details of near or distant objects refers to
A)visual field
B)visual acuity
C)field loss
D)legally blind

Accepted Answer

Visual acuity refers to the sharpness of vision, particularly the ability to discern details of near or distant objects. Visual field refers to the entire area that can be seen without moving the eyes, and field loss refers to a partial or total loss of this area. Legally blind refers to a legal definition of visual impairment that varies by country, but often includes a visual acuity of 20/200 or less in the better eye with best correction, or a visual field of less than 20 degrees.

Question 14

The transparent outer portion of the eyeball that transmits light to the retina.
A)cornea
B)iris
C)lens
D)macula

Accepted Answer

The cornea is the transparent outer portion of the eyeball that acts as a protective covering and helps transmit light to the retina. It is the first component that light passes through when entering the eye.

Question 15

A restriction to the visual field within the quadrant regions to the right,left,up,and down while gazing straight ahead.
A)visual field
B)visual acuity
C)field loss
D)legally blind

Accepted Answer

This is describing a field loss, which means that there are portions of the visual field that cannot be seen. This is different from visual acuity, which refers to the sharpness of vision, or being legally blind, which has a specific legal definition based on visual acuity and visual field.

Question 16

Factors that may place an infant,toddler,or child at risk for visual impairment include all EXCEPT
A)prematurity or low birth weight
B)congenital cataracts
C)difficult delivery resulting in low Apgar scores
D)normal pregnancy and delivery

Accepted Answer

The other options (prematurity or low birth weight, congenital cataracts, difficult delivery resulting in low Apgar scores) are all factors that have been associated with an increased risk of visual impairment. A normal pregnancy and delivery would not typically place an infant, toddler, or child at risk for visual impairment.

Question 17

Instructional goals for most students with visual impairment include all of the following EXCEPT
A)communication skills
B)social competency
C)employability
D)medical needs

Accepted Answer

Instructional goals for most students with visual impairment include communication skills, social competency, and employability. However, addressing medical needs is typically the responsibility of healthcare professionals and is not a primary goal of educational programs for students with visual impairments.

Question 18

If the cornea is damaged through trauma or disease,
A)the inner area of the eye may become infected which could result in permanent visual impairment.
B)the result may be a loss of visual acuity as well as a loss in the visual field.
C)the function of light control will be interrupted and the individual can become photophobic.
D)vascular growth has been interrupted by premature birth.

Accepted Answer

Damage to the cornea can lead to infection of the inner eye, potentially causing permanent visual impairment.

Question 19

The inner layer of the eye containing light-sensitive cells that connect with the brain through the optic nerve.
A)cornea
B)iris
C)retina
D)macula

Accepted Answer

The retina is the inner layer of the eye that contains light-sensitive cells, such as rods and cones, that transmit visual information to the brain through the optic nerve. The cornea is the clear outer covering of the eye, the iris is the colored part of the eye that controls the size of the pupil, and the macula is a small area in the center of the retina that is responsible for sharp, central vision.

Question 20

The area of best central vision located behind the retina.
A)vitreous humor
B)lens
C)pupil
D)macula

Accepted Answer

The macula is the area of the retina responsible for high acuity vision, making it the best central vision. The vitreous humor, lens, and pupil all play important roles in vision, but they do not specifically contribute to the area of best central vision behind the retina.
