with no noticeable loss of vision until the disease is advanced.

Q

from the eye. Clients who have decreased accommodation to view
closer print will have to move the card or newspaper further away
to see it.

Q

Use this test for middle-aged clients and others who complain of difficulty reading.

A

Test near visual acuity

26
Q

Normal near visual acuity is

A

14/14 This means that
the client can read what the normal eye can read from a distance of 14 inches.

27
Q

(impaired near vision) is indicated when the client moves the chart away from the eyes to focus on the print. It is caused by decreased accommodation.

  • is a common condition in
    clients over 45 years of age.
A

Presbyopia

28
Q

what are the normal visual field degrees?

A
  • Inferior: 70 degrees
  • Superior: 50 degrees
  • Temporal: 90 degrees
  • Nasal: 60 degrees
29
Q

This test assesses parallel alignment of the eyes. Hold a penlight approximately 12 inches
from the client’s face. Shine the light toward the bridge of the nose while the client stares straight ahead. Note the light reflected on
the corneas.

A

Perform corneal light reflex test

30
Q

test detects deviation in alignment or strength and slight deviations in eye movement by interrupting
the fusion reflex that normally keeps the eyes parallel

A

Perform cover test

31
Q

a is a term used to describe misalignment that occurs only when fusion reflex is blocked.

A

Phoria

32
Q

is constant malalignment of the eyes.

A

Strabismus

33
Q

is a specific type of misalignment:

A

Tropia

34
Q

is an inward turn of the eye

A

Esotropia

35
Q

is an outward turn of the eye

A

exotropia

36
Q

test which assesses eye muscle strength and cranial nerve function

A

Perform position/ cardinal fields of gaze

37
Q

—an oscillating (shaking) movement of the eye—may be associated with an inner ear disorder, multiple sclerosis, brain lesions, or narcotics use.

A

Nystagmus

38
Q

Drooping of the upper lid

A

ptosis

39
Q

inverted lower lid is a condition called
may cause pain and injure
the cornea as the eyelash brushes against the conjunctiva and cornea.

A

entropion

40
Q

an everted lower eyelid, results in
exposure and drying of the conjunctiva

A

Ectropion

41
Q

Redness and crusting along the lid margins suggest

A

seborrhea or blepharitis, an infection caused by Staphylococcus aureus

42
Q

a hair follicle infection causes local redness, swelling, and pain

A

Hordeolum (stye)

43
Q

an infection of the meibomian
gland (located in the eyelid), may produce extreme swelling of the lid, moderate redness, but minimal pain

A

chalazion

44
Q

Protrusion of the eyeballs accompanied by
retracted eyelid margins is termed

A

exophthalmos

45
Q

Generalized redness of the conjunctiva suggests

A

conjunctivitis (pink eye).

46
Q

Yellowish nodules on the bulbar conjunctiva are called

A

pinguecula

47
Q

is a local, noninfectious inflammation of the sclera. The condition is usually
characterized by either a nodular appearance
or by redness with dilated vessels

A

Episcleritis

48
Q

a normal condition in older
clients, appears as a white arc around the limbus. The condition
has no effect on vision.

A

Arcus senilis

49
Q

Normal pupil size

A

3 to 5 mm

50
Q

An inequality in pupil size of less than 0.5 mm occurs in 20%
of clients. This condition, called

A

Anisocoria

51
Q

The normal consensual pupillary response is

A

constriction.

52
Q

Accommodation occurs when the client moves his or her focus of vision from a distant point to
a near object, causing the pupils to constrict. Hold your finger or a pencil about 12 to 15 inches from the client. Ask the client to focus on your finger or pencil and to remain
focused on it as you move it closer in toward the eyes

A

Test accommodation of pupils

53
Q

The normal pupillary response of accommodation of the pupils are?

A

constriction nof the pupils and convergence of the eyes when focusing on a near object

54
Q

appears as a swollen disc with blurred margins, a hyperemic (blood-filled) appearance, more visible and more numerous disc
vessels, and lack of visible physiologic cup

A

Papilledema, or swelling of the optic disc

55
Q

is evidenced by the disc being
white in color and a lack of disc vessels. This condition is caused by the death of optic nerve fibers

A

Optic atrophy

56
Q

occurs when injury causes red
blood cells to collect in the lower half of the anterior chamber of the eye

A

hyphemia

57
Q

usually results from an inflammatory response in which white blood cells
accumulate in the anterior chamber and produce cloudiness in front of the iris

A

Hypopyon

58
Q

an inward drift of eye

A

esophoria

59
Q

outward drift of the eye

A

exophoria

60
Q

Constant malalignment of the eye axis, defined according to the direction toward the eye drifts and may cause amblyopia

A

Strabismus (tropia)

61
Q

Normal in young children, the pupils will appear at the center canthus (due to epicanthic fold)

A

Pseudotrabismus

62
Q

Also known as lazy eye reduced vision in one eye caused by abnormal visual development early in life.

A

Amblyopia
