Q1.
A patient presents with a best-corrected visual acuity of 20/25 and a relative afferent
pupillary defect. Which of the following is the most likely diagnosis?
A. Cataract B. Optic neuritis
C. Macular degeneration D. Amblyopia
Correct: B - Optic neuritis
Rationale:A relative afferent pupillary defect (RAPD) indicates an optic nerve lesion, most
commonly optic neuritis. Cataracts cause decreased vision without RAPD. Macular
degeneration typically affects central vision but does not cause RAPD. Amblyopia does not
produce RAPD.
Q2.
Which of the following instruments measures corneal thickness using the principle of
optical coherence?
A. Keratometer B. Ultrasound pachymeter
C. Specular microscope D. Optical coherence tomography (OCT)
Correct: D - Optical coherence tomography (OCT)
Rationale:OCT uses low-coherence interferometry to produce high-resolution cross-sectional
images of the cornea, measuring thickness. Keratometer measures corneal curvature.
Ultrasound pachymeter uses sound waves. Specular microscope images endothelial cells.
Q3.
A patient's keratometry readings are 42.00 D @ 90 and 43.50 D @ 180. What is the amount
and axis of the patient's astigmatism?
A. 1.50 D with-the-rule B. 1.50 D against-the-rule
C. 1.50 D oblique D. 0.75 D with-the-rule
Correct: B - 1.50 D against-the-rule

YEAR AND Optometric Technology AND Paraoptometric Studies Undergraduate YEAR 3 / Graduate
Rationale: The flattest meridian is at 90 (42.00 D) and the steepest at 180 (43.50 D), giving
1.50 D of astigmatism. Since the steepest meridian is horizontal, this is against-the-rule
astigmatism. The axis of the correcting cylinder would be at 90, but the amount is 1.50 D.
Q4.
Which of the following is the primary purpose of using a red-free filter during fundus
examination?
A. Enhance visualization of the retinal nerve B. Reduce glare from the patient's lens
fiber layer
C. Improve contrast of retinal blood vessels D. Facilitate fluorescein angiography
Correct: A - Enhance visualization of the retinal nerve fiber layer
Rationale:Red-free (green) light is absorbed by hemoglobin and enhances the visibility of the
retinal nerve fiber layer, making defects more apparent. It does not primarily reduce glare,
improve vessel contrast (though it does enhance vessels, the main purpose is NFL), or
facilitate angiography.
Q5.
A patient is prescribed a medication that causes pupillary dilation. Which of the following
classes of drugs is most likely responsible?
A. Cholinergic agonists B. Beta-blockers
C. Alpha-adrenergic agonists D. Carbonic anhydrase inhibitors
Correct: C - Alpha-adrenergic agonists
Rationale:Alpha-adrenergic agonists (e.g., phenylephrine) stimulate the dilator muscle of the
iris, causing mydriasis. Cholinergic agonists constrict the pupil (miosis). Beta-blockers reduce
aqueous production without direct pupillary effect. Carbonic anhydrase inhibitors also reduce
aqueous production.
Q6.
Which of the following best describes the principle of the Amsler grid test?
A. It measures central visual field using B. It assesses peripheral visual field using
patient-reported distortions kinetic perimetry
C. It evaluates color vision using D. It tests contrast sensitivity using
pseudoisochromatic plates sine-wave gratings
Correct: A - It measures central visual field using patient-reported distortions
