AOC Amblyopia Management and Treatment 3

Question 1

PEDIG research found that patching combined with near visual activities outperformed patching alone primarily because:

Accepted Answer

Active near tasks require sustained foveal engagement of the amblyopic eye, enhancing the treatment effect

Answer

Near activities activate entirely different cortical regions not stimulated by distance patching

Answer

Near activities prevent children from removing the patch during school hours

Answer

Combining near activities with patching reduces the risk of reverse amblyopia

Question 2

Bangerter foils are used as an alternative to conventional eye patching primarily because:

Accepted Answer

They are less cosmetically conspicuous, which may improve compliance especially in older children

Answer

They provide stronger penalization than full occlusion patches

Answer

They directly stimulate the amblyopic retina via diffuse light transmission

Answer

Randomized trials have shown them to be superior to patching for all amblyopia severities

Question 3

What interocular best-corrected visual acuity difference is generally required to diagnose amblyopia?

Accepted Answer

2 lines on the Snellen chart

Answer

1 line on the Snellen chart

Answer

3 lines on the Snellen chart

Answer

4 lines on the Snellen chart

Question 4

Reverse (occlusion) amblyopia can develop when:

Accepted Answer

Excessive patching of the fellow eye reduces its visual acuity below that of the originally amblyopic eye

Answer

The amblyopic eye develops nystagmus as a response to prolonged monocular patching

Answer

Both eyes reach equal, symmetrically reduced visual acuity during concurrent treatment

Answer

The patient develops photophobia and avoids using the patched amblyopic eye

Question 5

After successful amblyopia treatment, maintenance patching is sometimes recommended in order to:

Accepted Answer

Prevent regression of visual acuity gains while the visual system remains developmentally plastic

Answer

Permanently stimulate the amblyopic eye throughout adulthood

Answer

Treat residual strabismus that persists after full acuity recovery

Answer

Ensure the spectacle prescription remains accurate as the eye grows

Question 6

Which statement best reflects current evidence regarding amblyopia treatment initiated beyond the traditional critical period?

Accepted Answer

Meaningful improvement is still possible, though outcomes are generally more limited than in younger children

Answer

Treatment is entirely ineffective once a patient reaches 9 years of age

Answer

Treatment efficacy in adults is equivalent to that in children under 7 years old

Answer

Only surgical interventions can improve acuity after the critical period has closed

Question 7

Which clinical test is used to directly visualize the type and location of eccentric fixation in a strabismic amblyopic eye?

Accepted Answer

Visuoscopy (fixation ophthalmoscopy with a projected fixation target)

Answer

Maddox rod test

Answer

Bagolini striated lens test

Answer

Worth four-dot test
