Module 3: HEENT Flashcards

1
Q

What is the purpose of the confrontation test?

A

It is a gross measure of peripheral vision. It works by comparing the peripheral vision of the patient with that of the examiner by estimating the angle between the axis of the eye looking directly at the examiner and the peripheral axis where the object is first seen. (It assumes that the peripheral vision of the examiner is WNL.)

Q

How do you perform the confrontation test?

A
  1. Stand 2 ft away at eye level with the patient.
  2. Pt covers one eye while the examiner covers their own opposite eye.
  3. Patient looks directly into the examiner’s eye while the examiner advances an object or finger from the periphery from a superior, inferior, nasal, and temporal direction.
  4. The patient indicates at which point the object or finger is seen.

Q

Normal findings of the confrontation test?

A

The patient should see the finger/object of examiner at approx. the same time that it’s seen by examiner.
Approximates fields describe an angle of:
-50 degrees superiorly
-70 degrees inferiorly
-60 degrees nasally
-90 degrees temporally

Q

What is a Tangent screen?

A

It provides a more precise measure of peripheral vision than the confrontation test. A patient is asked to stare at the center of a screen while the examiner maps the patient’s peripheral vision by noting the patient’s response to objects placed onto the screen.

Q

What is the purpose of the cover test?

A

It detects phoria, a deviated alignment secondary to muscle weakness that may not be readily apparent on simple observation. This test works by disrupting the fusion reflex that normally keeps eyes parallel.

Q

Example 1 of a cover test:

A

The patient is asked to gaze straight ahead. Both eyes gazed parallel until the examiner covers the left eye. When the left eye is covered, the right eye drifts medially. When the cover was removed, the right eye jerked back into parallel position. Why?
The right eye is weaker. The fusion reflex was disrupted.

Example 2 of a cover test:

A

A patient was asked to gaze straight ahead. Both eyes gazed parallel until the examiner covered the left eye. When the left eye was covered, the right eye continued to gaze straight ahead. When the cover was removed, the left eye jerked back into parallel position. Why? The left eye is weaker.

Q

So what does the cover test do?

A

It detects small degrees of deviated alignment by interrupting the fusion reflex that maintains eyes in parallel alignment. During the test, the eye with weak muscles will drift when an eye is covered and will jerk back into alignment when uncovered.

Q

What is considered a normal finding for the corneal light reflex test?

A

In a patient with normal alignment, the light will be reflected at the same place on both corneas or very slightly medially on both pupils. If it is reflected at different places, this will indicate strabismus.

Q

What is visual acuity in a child?

A

Visual acuity is usually less. A reading of 20/50 may be normal for a child of 3; 20/40 may be normal for child of 4; 20/30 may be normal for a child of 5. The upper limits of normal vary +/- 10 feet among different sources.

Q

Diagnostic Positions Test interpretation:

Q

What does Nystagmus indicate?

A

May indicate an inner ear or neurological problem. May also indicate inebriation. Mild nystagmus at extreme lateral gaze is a normal finding. See chart on slide 44 to determine which muscle/cranial nerve is not functioning properly.

25
What is another name for the diagnostic positions test?
The test of extra ocular movement or EOMS.
26
What does the accommodation test measure?
Pupillary constriction and convergence of the aces of the eyes that normally occurs when eyes adjust for near vision.
27
How do you perform an accommodation test?
Have the patient focus on a distant object (this causes the pupils to dilate), then ask the patient to shift the gaze to the examiner's finger which is held about 3 in from the patient's nose. A normal response is constriction of the pupils and convergence of the eye's axes.
28
How to interpret an accommodation test:
An absence of either constriction or convergence or an asymmetric response is abnormal. (Ex. CN III damage will result in pupil dilation and lateral deviation of the eye.)
29
What is the purpose of the Ishihara Test?
Tests color vision
30
How do you perform the Ishihara test?
With one eye covered, the patient is asked to identify numbers or objects on a slide within a time frame of +/- 3 seconds. Patients who have various types of color vision will not be able to identify colored numbers or objects within patterns of dots.
31
What is the purpose of the Amsler Grid?
Used to test for defects in the central visual field. Such defects are typical of macular degeneration.
32
How do you test central vision with the Amsler Grid?
The Amsler grid is held at +/- 14 inches away. (Reading glasses may be worn.) With one eye covered, the patient stares at the central dot on the grid. Repeat with the other eye.
33
What are some abnormalities with the Amsler Grid?
Abnormalities indicated by wavy, crooked, or bent lines. Variances in box shape or size. Missing or discolored lines.
34
Patient reports that he is beginning to have difficulty seeing road signs until he gets close to them. What test would you use?
A test of visual acuity using the Snellen chart will determine if distance vision is a problem.
35
You notice that your patient didn't flinch as an object fell within inches of his left temple. It was only after it crashed that it caught your patient's attention. You suspect a deficit in his peripheral vision. How would you test his visual fields?
In order to screen for approximate peripheral vision, you would use the confrontation test. For more accurate testing, a tangent screen would be used.
36
A mother states "I think my son has lazy eye." How would you test for this?
The cover test is designed to detect "lazy eye" by disrupting the fusion reflex.
37
What are the tests of Visual Acuity?
Snellen Chart = Distance vision | Rosenbaum or Jaeger Cards = Near vision

Tips for using Ophthalmoscope
1. Darken the room and have the patient look off in the distance 2. Switch the ophthalmoscope light and turn the lens disc to the large round beam of white light 3. Turn lens disc to the 0 diopter 4. Hold the ophthalmoscope in your right hand to examine the patient’s right eye with your right eye; hold it in your left hand to examine the patient’s left eye with your left eye 5. Stand directly in front of the patient, 15 inches away, and start at an angle of 15 degrees lateral to the patient’s line of vision 6. Shine the beam of light onto the pupil and look for an orange glow; this is the red reflex 7. Follow the red reflex and move inward towards the nasal aspect of the visual field
