At what age does visual acuity typically reach adult levels (approximately 20/20) in normally developing children?
Answer: 5–6 years
Visual acuity typically matures to approximately 20/20 by age 5–6 years in normally developing children.
Which test is most appropriate for assessing visual acuity in a non-verbal 2-year-old child?
Answer: Teller Acuity Cards
Teller Acuity Cards use preferential looking to assess grating acuity in preverbal or nonverbal children.
Photoscreening devices detect amblyopia risk factors primarily by analyzing which feature?
Answer: Red reflex and corneal light reflexes
Photoscreening devices analyze the red reflex and corneal light reflections to detect media opacities, significant refractive errors, and strabismus.
The critical period for amblyopia treatment is primarily defined by:
Answer: Neural plasticity of the visual cortex
The critical period for amblyopia treatment is defined by the period of neural plasticity in the visual cortex during which visual development can be influenced.
Which condition is NOT considered an amblyopia risk factor?
Answer: Bilateral symmetric myopia of equal magnitude
Bilateral symmetric myopia does not create unequal visual input between the eyes, so it is not an amblyopia risk factor.
The Hirschberg test is used to estimate:
Answer: Angle of strabismus
The Hirschberg test estimates the angle of strabismus by observing the position of the corneal light reflex relative to the pupil center.
