IJCAHPO CERTIFIED OPHTHALMIC
TECHNICIAN (COT) CERTIFICATION
EXAM QUESTIONS AND ANSWERS.
VERIFIED 2025/2026.
What is NOT important when documenting the history of an ocular injury? - ANS presence of
others when the injury occurred
Which one of the following ocular conditions will LEAST likely present in a patient's family
history? - ANS conjunctivitis
When evaluating a patient for cataract surgery, which of the following systemic illness is LEAST
important? - ANS urinary incontinence
Which symptoms might suggest angle-closure glaucoma? - ANS rainbow colored halos
around lights
what is the correct interpretation of 1gtt tid OU - ANS one drop to both eyes three times a
day
A history of corticosteroid use of LEAST importance when ascertaining which condition? -
ANS macular degeneration

,A visual acuity of 20/200 obtained at a distance of 4 feet should be recorded as - ANS 4/200
If a patient's visual acuity measures 20/70 with correction and pinholes to 20/25, which of the
following is MOST likely? - ANS the patient needs distance correction
the lines of optotypes are what size in comparison to entire optotype - ANS 1/5
Reduced visual acuity without any detectable organic cause is referred to as - ANS amblyopia
A 55-year-old patient has worn glasses since childhood. Without glasses, the uncorrected vision
improves when looking through an occluder with perforation. This phenomenon is know as the
- ANS pinhole effect
What is the metric equivalent of 20/40 visual acuity? - ANS 6/12
Dynamic visual acuity refers to - ANS kinetic or moving vision
Measuring visual acuity with a potential acuity meter is useful for patients with - ANS catarcts
Near vision charts should be held how many inches from the eye? - ANS 14-16
If poor vision is simply due to refractive error, the acuity should improve with use of a(n) -
ANS pinhole disc
What is the recommended distance for assessing visual acuity? - ANS 20'

, If a person can clearly see an object at 20 feet that can be seen at 60 feet by a person with no
refractive error, their visual acuity is said to be - ANS 20/60
If a patient is unable to distinguish the largest letter on a Snellen chart, the assistance should -
ANS determine if the patient can count fingers at a given distance
In visual assessment, an infant would be expected to reach for toys by the age of - ANS 4-6
months
The visual defect in which there is a complete type of nerve fiber bundle defect emanating from
the blind spot, arching over central fixation, and ending on the horizontal line is a -
ANS Bjerrum scotoma
Homonymous congruous visual field defects with macular sparing are located in what part of
the visual pathway? - ANS occipital cortex
The normal visual field is determined by the size of the test object employed and the distance at
which the test was made. With a 3 mm white target on the perimeter of a 330-degree radius,
the average peripheral limit is about - ANS 95 degrees outward, 75 degrees downward, 60
degrees inward and 60 degrees upward
What type of patient generally requires a threshold 24-degree central field test? -
ANS glaucoma
the MOST widely used method of visual field screening, requiring no special equipment, is -
ANS confrontation testing
Scotomas located immediately nasal or temporal to fixation are known as - ANS paracentral
