AOC Evaluation & Continuing Education 2 — Questions and Answers
Question 1: Which prism test is most commonly used to quantify the magnitude of a horizontal strabismus deviation?
- Maddox rod test
- Prism and alternate cover test (Correct answer)
- Hirschberg test
- Krimsky test
Correct answer: Prism and alternate cover test
The prism and alternate cover test dissociates fusion and measures the full manifest plus latent deviation.
Question 2: What is the primary purpose of the Worth 4-dot test in orthoptic evaluation?
- Measure visual acuity
- Assess stereopsis
- Evaluate sensory fusion and suppression (Correct answer)
- Detect amblyopia
Correct answer: Evaluate sensory fusion and suppression
The Worth 4-dot test assesses whether a patient has binocular fusion, suppression, or diplopia under dissociated conditions.
Question 3: AOC Continuing Education Units (CEUs) must be completed within what time frame to maintain certification?
- Every 1 year
- Every 2 years
- Every 3 years (Correct answer)
- Every 5 years
Correct answer: Every 3 years
AOC certified orthoptists must accumulate the required CEUs within each 3-year recertification cycle.
Question 4: During an orthoptic evaluation for accommodative esotropia, which test best determines the AC/A ratio?
- Synoptophore test
- Gradient method using lenses (Correct answer)
- Red glass test
- Bagolini striated lens test
Correct answer: Gradient method using lenses
The gradient method measures deviation at distance with and without added lenses to calculate the accommodative convergence to accommodation ratio.
Question 5: A patient demonstrates 20 prism diopters of esotropia at distance and 35 prism diopters at near. This pattern suggests:
- Basic esotropia
- Divergence insufficiency
- High AC/A ratio esotropia (Correct answer)
- Sensory esotropia
Correct answer: High AC/A ratio esotropia
A significantly larger near deviation compared to distance deviation indicates a high AC/A ratio, characteristic of accommodative esotropia.
Question 6: Which form of continuing education is specifically recognized by the AOC for recertification credit?
- Any online medical course
- AOC-approved orthoptic symposia and courses (Correct answer)
- General ophthalmology CME only
- Hospital grand rounds without documentation
Correct answer: AOC-approved orthoptic symposia and courses
The AOC recognizes CEUs from AOC-approved symposia, workshops, and courses as valid for recertification.
Question 7: Stereoacuity of 40 seconds of arc on the Randot test indicates:
- No stereopsis
- Gross stereopsis only
- Fine stereopsis consistent with normal binocular vision (Correct answer)
- Monofixation syndrome
Correct answer: Fine stereopsis consistent with normal binocular vision
40 seconds of arc stereoacuity is within the range considered fine stereopsis, indicating good binocular function.
