COT test 1 UPDATED ACTUAL Questions and CORRECT Answers
Question: Why is 20 feet considered a practical distance for assessing distance visual acuity?
Correct Answer: At 20 feet, very little accommodation is required.
Question: What does the denominator represent in the distance visual acuity fraction ?
Correct Answer: The 50 represents the distance that a normal eye can see the chart letters, indicating the
normal eye can see the letters at 50 feet.
Question: What does improved vision through a pinhole indicate?
Correct Answer: It suggests that refractive error vision can be improved with eyeglasses or contact lenses.
Question: What type of testing determines the retina's ability to detect subtle differences in brightness or
shading?
Correct Answer: Contrast Sensitivity testing.
Question: What is the next step in evaluating a patient's visual acuity if they cannot see the line at the
standard distance?
Correct Answer: Repeating the distance visual acuity test at a shorter distance.
Question: What is the proper way to record visual acuity if the patient reads all but one letter on the line?
Correct Answer: It is recorded as -1.
Question: What type of glaucoma is associated with sudden rise in intraocular pressure and severe
symptoms?
Correct Answer: Acute angle-closure glaucoma, characterized by sudden decrease in vision, red eye, halos
around lights, nausea, and excruciating pain.
Question: Which type of glaucoma is known as the 'silent thief of sight' and why?
Correct Answer: Chronic open-angle glaucoma, due to its gradual and slow progression of vision loss.
Question: What is a classic sign of congenital glaucoma?
Correct Answer: Buphthalmos, which is an abnormally large eyeball.
Question: What condition occurs when the iris balloons forward, blocking aqueous flow?
Correct Answer: Iris Bombe.
Question: What procedure is performed to relieve pressure in the anterior chamber due to angle-closure
glaucoma?
Correct Answer: Laser Peripheral Iridotomy (LPI).
Question: Where is aqueous humor produced?
Correct Answer: By the ciliary body.
Question: What is the method used to measure intraocular pressure with a tonometer?
Correct Answer: Applanation, which measures the force needed to flatten the central cornea.
Question: What is the smallest object that can be clearly seen and distinguished at a distance?
