Free COT Optometry Questions and Answers — Questions and Answers
Question 1: Used to enhance the visibility of the external tissues of the eye when using fluorescein dye
- Exciter filter (Correct answer)
- Red free filter
- Cobalt/uv filter
- Barrier filter
Correct answer: Exciter filter
This filter is used to selectively allow specific wavelengths of light to pass through, which can excite fluorescein dye to fluoresce.
Question 2: Disease which is indicated by the presence of microaneurysms, dot/blot hemes, and lipid exudates from a leakage of the retinal vessels
- Glaucoma
- Macular Degeneration
- Retinal Detachment
- Diabetic Retinopathy (Correct answer)
Correct answer: Diabetic Retinopathy
A diabetes complication that affects the eyes. It is indicated by the presence of microaneurysms, dot/blot hemorrhages, and lipid exudates due to leakage of retinal vessels.
Question 3: Gives the physician an estimate of a patient's potential visual acuity
- PAM Test (Correct answer)
- Metal Test Spheres
- Buphthalmos
- Iris Bombe
Correct answer: PAM Test
A test used to estimate a patient's potential visual acuity, often before cataract surgery, by projecting an eye chart image onto the retina.
Question 4: Downward movement
- Inferior Oblique
- Inferior Rectus (Correct answer)
- Lateral Rectus
- Superior Rectus Muscle
Correct answer: Inferior Rectus
This muscle is responsible for downward movement (depression) of the eye.
Question 5: Alkaline
- ph of 7.0 (Correct answer)
- pH of 7.5
- potassium level of 5.9 meq/l
- bun level of 25 mg/dl
Correct answer: ph of 7.0
This is neutral, neither acidic nor alkaline.
Question 6: Consists of a footplate with a central moveable plunger fitted into a barrel
- Goldmann Applanation Tonometer (Correct answer)
- Schiotz Tonometer
- Helmholtz Applanation Tonometer
- Noncontact Tonometer
Correct answer: Goldmann Applanation Tonometer
This device uses a flat-tipped probe to flatten the cornea and measure intraocular pressure, but it does not have a footplate and plunger design.
Question 7: Parallel movement of both eyes
- Versions (Correct answer)
- Aberrations
- Phoria
- Ductions
Correct answer: Versions
Parallel movement of both eyes in the same direction. This term specifically refers to the coordinated movement of both eyes.
Question 8: Provided by the manufacturer, with known radius of curvature, to be used for the calibration of the manual keratometer
- Axial Length Measurement
- Cobalt/uv Filter
- Metal Test Spheres (Correct answer)
- Schiotz Tonometer
Correct answer: Metal Test Spheres
Provided by the manufacturer with a known radius of curvature, these are used for the calibration of a manual keratometer to ensure accuracy in measuring the curvature of the cornea.
Question 9: Movement toward the midline of the body
- Inversion
- Evisceration
- Adduction (Correct answer)
- Enucleation
Correct answer: Adduction
The movement of a body part toward the midline of the body. This term is used to describe the movement of limbs or other body parts.
Question 10: Longest-acting mydriatic
- Timolol
- Atropine (Correct answer)
- Epinephrine
- Acetylcholine
Correct answer: Atropine
Atropine is a muscarinic antagonist that causes pupil dilation (mydriasis) and paralysis of accommodation (cycloplegia). It has a relatively long duration of action compared to other mydriatics.
Question 11: Transient viral vesicles that infect the facial area
- Herpes Simplex Virus Type 1 (Correct answer)
- Herpes Simplex Virus Type 4
- Herpes Simplex Virus Type 5
- Herpes Simplex Virus Type 2
Correct answer: Herpes Simplex Virus Type 1
