Prometric Exam Questions for Optometrists 2026: 15 Practice MCQs with Answers and Rationale for the OPT5581 Paper

Optometrists (OPT5581) in the Gulf work in optical chains, hospital eye departments and diabetic screening programmes, and the Prometric paper tests all three: accurate refraction and prescribing, contact lens practice, detecting disease and knowing when to refer. It is usually 100 to 150 single-best-answer questions in 2 to 3 hours, with a pass mark around 55%.

The fifteen questions below follow the blueprint. Allow about 70 seconds each and read every rationale. Refraction arithmetic and referral criteria are reliable marks.

For eligibility and the syllabus, read the optometrist guide. For timed papers use the Optometrist bank.

Refraction and prescribing

Question 1

A prescription reads −2.00 / −1.50 × 180. Transposed to plus-cylinder form it is:

1. −2.00 / +1.50 × 180
2. −3.50 / +1.50 × 90
3. −0.50 / +1.50 × 90
4. −3.50 / +1.50 × 180

Answer: B. Add the cylinder to the sphere (−2.00 + −1.50 = −3.50), change the cylinder sign (+1.50) and rotate the axis by 90 degrees (180 to 90).

Question 2

A 45-year-old emmetrope complains of difficulty reading small print at 40 cm. The likely diagnosis and a typical first reading addition are:

1. Myopia; −1.00 DS
2. Presbyopia; about +1.00 to +1.25 DS, determined by amplitude of accommodation and working distance
3. Hyperopia; +4.00 DS
4. Cataract; surgery

Answer: B. The addition should leave about half the amplitude of accommodation in reserve; over-plussing reduces the range of clear vision.

Question 3

Retinoscopy at a working distance of 67 cm gives a neutral reflex with +3.00 DS in the trial frame. The patient's refractive error is:

1. +3.00 DS
2. +1.50 DS, after subtracting the working distance correction of 1.50 D
3. +4.50 DS
4. −1.50 DS

Answer: B. The working distance of 67 cm equals 1.50 D, which is subtracted from the neutralising lens.

Question 4

A 7-year-old has +4.00 DS of hyperopia in both eyes with an esotropia at near that reduces with the full correction. The management is:

1. No glasses; the child will grow out of it
2. Full cycloplegic hyperopic correction for accommodative esotropia, with bifocals if a residual near deviation persists, and amblyopia treatment if acuity differs between the eyes
3. Surgery first
4. Minus lenses

Answer: B. Accommodative esotropia is treated optically; cycloplegic refraction is essential in children because active accommodation masks hyperopia.

Binocular vision and paediatrics

Question 5

Cover test shows the uncovered eye moving outward to take up fixation when the fellow eye is covered. This indicates:

1. Exophoria
2. Esotropia (a manifest inward deviation)
3. Exotropia
4. Orthophoria

Answer: B. On the cover-uncover test, outward movement of the uncovered eye means it was deviated inward. Movement on the alternate cover test only indicates a phoria.

Question 6

A 5-year-old has acuity of 6/6 in the right eye and 6/24 in the left with no structural abnormality and a refraction of +0.50 right and +3.50 left. The diagnosis and treatment are:

1. Normal variation; review in five years
2. Anisometropic amblyopia; full refractive correction first, then part-time occlusion of the better eye or atropine penalisation, monitored every few weeks
3. Cataract; surgery
4. Retinoblastoma; urgent referral

Answer: B. Amblyopia treatment is most effective before about seven years; glasses alone improve acuity in many children before occlusion starts.

Contact lenses

Question 7

A soft contact lens wearer presents with a painful red eye, photophobia and a central corneal infiltrate after swimming in lenses. The optometrist should:

1. Prescribe a topical steroid
2. Stop lens wear, keep the lens and case for culture, and refer same day to ophthalmology for suspected microbial keratitis, with Acanthamoeba considered given water exposure
3. Replace the lens and review in a week
4. Advise artificial tears only

Answer: B. Central infiltrates with pain are sight-threatening and outside the optometrist's management scope in most Gulf jurisdictions.

Question 8

A rigid gas-permeable lens fluorescein pattern shows central pooling with mid-peripheral bearing. The fit is:

1. Flat; flatten the base curve further
2. Steep; the base curve should be flattened to achieve alignment
3. Aligned; dispense
4. Too large; reduce diameter only

Answer: B. Central pooling indicates the lens is steeper than the cornea. A flat fit shows central touch with peripheral pooling.

Question 9

A 15-year-old myope progressing by 1.00 D a year asks about slowing progression. Evidence-based options include:

1. Under-correcting the spectacles
2. Low-dose atropine, myopia-control soft contact lenses or spectacle lenses with peripheral defocus designs, orthokeratology, and increased outdoor time, with ophthalmology involvement for atropine
3. Bifocal glasses for everyone
4. Nothing can be done

Answer: B. Under-correction accelerates progression. Myopia control is now standard advice for progressing children.

Ocular disease and screening

Question 10

Which combination of findings should prompt referral for suspected primary open-angle glaucoma?

1. Intraocular pressure of 14 mmHg with a cup-disc ratio of 0.3
2. Intraocular pressure above 21 mmHg, a cup-disc ratio of 0.7 or asymmetry of 0.2 or more between the eyes, thinning of the neuroretinal rim, or a visual field defect, with a family history raising suspicion
3. Mild myopia only
4. A pinguecula

Answer: B. No single parameter diagnoses glaucoma; corneal thickness influences pressure readings and risk. Gulf referral pathways set thresholds optometrists must know.

Question 11

Diabetic eye screening shows a few microaneurysms and small blot haemorrhages in one quadrant without macular involvement. The grade and action are:

1. Proliferative retinopathy; urgent referral
2. Mild non-proliferative diabetic retinopathy; annual screening, optimisation of glycaemic and blood pressure control, and patient education
3. No retinopathy; discharge
4. Maculopathy; laser

Answer: B. Referral is triggered by moderate to severe NPDR, any proliferative disease, or macular involvement. Screening intervals shorten with severity.

Question 12

A 68-year-old reports gradual distortion of straight lines in one eye; Amsler grid shows metamorphopsia and the macula shows drusen with a possible subretinal haemorrhage. The action is:

1. Reassure and recheck in a year
2. Urgent referral (within days) for suspected wet age-related macular degeneration, because anti-VEGF treatment preserves vision if started early
3. Prescribe new glasses
4. Vitamin supplements only

Answer: B. Dry AMD is monitored; new distortion or haemorrhage suggests conversion to wet AMD and is time-critical.

Question 13

A patient has a sudden painless loss of vision in one eye to hand movements, a relative afferent pupillary defect, a pale retina with a cherry-red spot at the fovea. The diagnosis and action are:

1. Cataract; routine referral
2. Central retinal artery occlusion; emergency referral within hours, treated as a stroke equivalent with vascular risk assessment, including exclusion of giant cell arteritis in older patients
3. Conjunctivitis; drops
4. Refractive change; new glasses

Answer: B. Vision rarely recovers, but the event signals high stroke risk; same-day medical assessment is required.

The red eye and low vision

Question 14

Which red eye can the optometrist usually manage without referral in most Gulf jurisdictions?

1. A painful eye with a fixed mid-dilated pupil and hazy cornea
2. Bilateral itchy, watery eyes with papillae and a seasonal history, treated with topical antihistamine or mast cell stabiliser drops, cold compresses and allergen avoidance
3. A red eye with corneal infiltrate in a lens wearer
4. A red eye with reduced vision and photophobia after trauma

Answer: B. Allergic conjunctivitis is within scope; pain, reduced vision, photophobia, corneal involvement and pupil abnormalities are referral signs. Prescribing rights for optometrists vary by Gulf authority.

Question 15

A patient with stable advanced macular degeneration has acuity of 6/60 and wants to read. The most useful low-vision aid for near tasks is:

1. A standard +2.50 reading addition
2. A high-plus reading addition or hand or stand magnifier calculated from the required magnification (for example about 4× to reach near N8 from N32), with task lighting and eccentric viewing training
3. Sunglasses
4. Contact lenses

Answer: B. Magnification is calculated from the present and target acuities; lighting and contrast often help as much as the aid.

How to use these questions

• Drill refraction arithmetic: transposition, working distance, vertex distance, reading additions.
• Memorise referral criteria for glaucoma, diabetic retinopathy, AMD and the red eye.
• Know contact lens fitting signs and complications and the scope of practice under your authority.
• Practise under time in the Optometrist bank, using the error-log method.

Ophthalmologists sit a separate paper (ophthalmology sample questions). Other allied health banks are listed in allied health question banks. When you hold eligibility, join the GCC talent pool; optical chains and hospital eye departments across the Gulf recruit optometrists continuously.
