Question 1

What is amblyopia?

Accepted Answer

Reduced visual acuity in one or both eyes not correctable by glasses alone

Answer

Amblyopia (lazy eye) is reduced best-corrected visual acuity caused by abnormal visual development, not explained by structural ocular disease.

Question 2

What is the most common cause of amblyopia in children?

Accepted Answer

Strabismus

Answer

Strabismic amblyopia is the most common form, occurring when the brain suppresses the image from a misaligned eye to avoid diplopia.

Question 3

At what age is the visual system most plastic and amblyopia treatment most effective?

Accepted Answer

Under 7–8 years

Answer

The critical period for visual development closes around age 7–8; treatment is most effective before this window closes.

Question 4

Which type of strabismus involves an eye turning inward toward the nose?

Accepted Answer

Esotropia

Answer

Esotropia is defined as convergent strabismus—the eye deviates inward (toward the nose).

Question 5

The Hirschberg test assesses what in pediatric eye exams?

Accepted Answer

Corneal light reflex symmetry to detect strabismus

Answer

The Hirschberg (corneal light reflex) test shines a light at the eyes and checks whether the reflected reflex is centered and symmetric, screening for strabismus.
