AOC Amblyopia Management and Treatment

Question 1

Which best defines amblyopia?

Accepted Answer

Reduced best-corrected visual acuity in one or both eyes without identifiable structural or pathological cause

Answer

Reduced visual acuity caused exclusively by uncorrected refractive error

Answer

Visual loss resulting from optic nerve damage during the critical period

Answer

Decreased acuity caused solely by media opacity present at birth

Question 2

Which type of amblyopia results from a significant difference in refractive error between the two eyes?

Accepted Answer

Anisometropic amblyopia

Answer

Strabismic amblyopia

Answer

Deprivation amblyopia

Answer

Organic amblyopia

Question 3

What is the generally accepted critical period during which amblyopia treatment is most effective?

Accepted Answer

Birth to approximately 7–9 years of age

Answer

Birth to approximately 2 years of age

Answer

Birth to approximately 12 years of age

Answer

Birth to approximately 18 years of age

Question 4

What is the recommended first step in managing most forms of amblyopia?

Accepted Answer

Prescribing and ensuring consistent wear of full optical correction

Answer

Immediate full-time patching of the fellow eye

Answer

Surgical correction of any underlying strabismus

Answer

Starting daily atropine penalization of the better-seeing eye

Question 5

What degree of hyperopic anisometropia is generally considered sufficient to induce anisometropic amblyopia?

Accepted Answer

≥1.00 D

Answer

≥0.50 D

Answer

≥3.00 D

Answer

≥5.00 D

Question 6

In amblyopia evaluation, the neutral density filter (NDF) test primarily helps differentiate:

Accepted Answer

Organic (structural) vision loss from functional amblyopia

Answer

Strabismic amblyopia from anisometropic amblyopia

Answer

Deprivation amblyopia from refractive amblyopia

Answer

Central fixation from eccentric fixation

Question 7

The 'crowding phenomenon' observed in amblyopia refers to which finding?

Accepted Answer

Greater difficulty identifying optotypes presented in rows compared with single isolated optotypes

Answer

Reduced peripheral visual field in the amblyopic eye

Answer

Increased glare sensitivity in the amblyopic eye under high-contrast conditions

Answer

Diplopia experienced when fixating on groups of closely spaced objects
