Visual Evoked Potential (VEP)
Snellen chart
Preferential Looking Test
Which acuity test is best for a child under the age of 2 who cannot respond verbally?

Preferential Looking Test
Kay Picture
Which VA test is most appropriate for preschool children who do not know their letters?
Snellen chart
Cardiff Acuity Test
Sheridan Gardiner
LogMAR chart
What is a key advantage of the LogMAR chart over the Snellen chart?
It is easier to use
It is more precise and standardized
It requires no literacy
It is better for measuring near vision
What does a "6/18" visual acuity score on the Snellen chart signify?
The person can see at 18 metres what a normal person can see at 6 metres
The person has a perfect vision
The person can see at 6 metres what a normal person can see at 18 metres
The person has a significant refractive error
In which test do children identify the orientation of the letter "E"?
HOTV chart
Sheridan Gardiner
LogMAR chart
Tumbling E chart
What is the primary purpose of visual acuity testing?
To assess depth perception
To measure the sharpness or clarity of vision
To detect colour blindness
To check for eye alignment
An objective, involuntary test used to detect vision in a patient claiming bilateral blindness involves a rotating drum with vertical black and white stripes. The examiner looks for rhythmic eye movements as the drum rotates. What is this test called?
Menace reflex test
Finger-to-nose test
Optokinetic nystagmus (OKN) test
Graefe's test
How do you record the results of a visual acuity test?
By noting the number of correct answers the patient gives
By using a Snellen fraction or LogMAR score
By the patient's ability to describe their vision
By comparing the results of monocular and binocular testing
In testing visual acuity, if the patient is unable to identify any letters on the Snellen chart, you should next test for the ability to?
Identify position of a stationary light
Identify presence of a stationary light
Count fingers
Identify direction of hand movements
A patient claims total blindness in one eye. During the examination, a prism is placed base-out in front of the "good" eye while the patient fixates on a distant object with both eyes open. If the patient has binocular vision, what is the expected eye movement?
The good eye moves inward and the "blind" eye shows a refixation movement
The good eye moves inward and the "blind' eye remains stationary
The good eye moves outward and the "blind" eye shows a compensatory movement
Both eyes remain stationary
A "mirror test" for malingering involves an examiner slowly moving a large mirror in front of a patient who claims bilateral blindness. If the patient has sight, what will occur?
The patient's pupil will dilate
The patient will demonstrate optokinetic nystagmus
The patient's eye will make small, involuntary tracking movements
The patient will complaint of a headache
In a "fogging method" for detecting monocular malingering, a strong convex (+10D) is placed in front of the patient's good eye while they attempt to read a distance chart with both eyes open. What result suggests malingering?
The patient reads a line smaller than their claimed vision in the affected eye
The patient is unable to read any letters
The patient reports clearer vision in the good eye
The patient's pupil constrict
A patient who claims total blindness in one eye is asked to wear red-and-green goggles and read a series of letters with some printed in red and some in green. The letter F is printed in red and the letter A is printed in green. If the patient claims their right eye is blind (with the red lens over it), which of the following outcomes would confirm malingering?
The patient reads all the letters correctly
The patient reads only the green letters
The patient reads only the red letters
The patient claims they cannot see any letters
A patient claims partial bilateral vision loss. When testing their visual field using kinetic perimetry, the visual filed size remains the same regardless of the test distance. What type of visual filed is this known as?
A non-specific contraction
A homonymous hemianopia
A tubular or "gun-barrel" field
A star-shaped defect
