CPO CPO Clinical Principles and Procedures 3

Question 1

A patient with early-stage glaucoma has a reliable Humphrey Visual Field (HVF) 24-2 test that appears normal.
However, the optometrist suspects central defects based on OCT findings.
Which of the following ancillary tests would be most appropriate for the paraoptometric to perform to investigate this specific concern?

Accepted Answer

A 10-2 visual field test to get higher resolution of the central area.

Answer

A 30-2 visual field test to screen a wider area.

Answer

Confrontation visual fields to quickly assess peripheral vision.

Answer

An Amsler grid test to check for macular distortion.

Question 2

A long-time progressive lens wearer complains of a persistent 'swimming' sensation and intermittent blur with their new glasses, despite the Rx and measurements being verified as correct. The frame has been adjusted for optimal pantoscopic tilt and face form. What is the most likely underlying cause for this non-adapt issue?

Accepted Answer

The progressive lens design is too 'hard' compared to their previous pair.

Answer

The vertex distance is too short.

Answer

The base curve of the new lenses is too flat.

Answer

The patient has developed a binocular vision disorder.

Question 3

During a contact lens follow-up, a patient wearing monthly toric lenses complains of fluctuating vision, especially after blinking. Upon slit lamp examination, the paraoptometric notes the toric orientation marking is consistently rotated 15 degrees nasally in the right eye. The over-refraction is +0.25 -0.75 x 100. The current lens is 8.6 BC, 14.5 Diam, -2.00 -1.25 x 085. Applying the LARS rule, what new diagnostic lens axis should be ordered?

Accepted Answer

070 degrees

Answer

115 degrees

Answer

100 degrees

Answer

055 degrees

Question 4

A 10-year-old is undergoing amblyopia therapy. The prescribed regimen is patching the dominant eye for two hours daily. The parents report inconsistent compliance and ask about alternatives. Which of the following is an equally effective, evidence-based alternative for treating moderate amblyopia in this age group?

Accepted Answer

Weekend-only atropine penalization of the dominant eye.

Answer

Wearing a Bangerter filter full-time over the dominant eye.

Answer

Increasing near-vision therapy activities without patching.

Answer

Switching to an eye patch with a more engaging design.

Question 5

A paraoptometric is assisting with a low vision evaluation for a patient with advanced macular degeneration. The patient needs to read a newspaper. Which of the following devices would be most appropriate to try first, considering it allows for a wide field of view and keeps the hands free for holding the paper?

Accepted Answer

High-plus spectacle-mounted microscopes.

Answer

A hand-held monocular telescope.

Answer

A closed-circuit television (CCTV) magnifier.

Answer

A hand-held dome magnifier.

Question 6

During patient triage, a 68-year-old male calls complaining of a 'curtain' coming down over the vision in his right eye that started 30 minutes ago, but he reports no pain or redness. He also mentions a history of high cholesterol. What is the most critical and immediate action the paraoptometric should take?

Accepted Answer

Book an urgent, same-day appointment with the optometrist.

Answer

Schedule the patient for the next available routine eye exam.

Answer

Advise the patient to monitor the symptom and call back if it worsens.

Answer

Instruct the patient to go to the nearest emergency room immediately.
