Which vision screening approach does the American Academy of Pediatrics recommend for children aged 3–5 years?
Answer: Photoscreening or autorefraction
The AAP recommends photoscreening or autorefraction for children aged 3–5 years, as these instrument-based methods are reliable in young, pre-cooperative children.
Which neonatal ocular condition can cause permanent severe vision loss if not treated within the first weeks of life?
Answer: Congenital cataracts
Congenital cataracts cause visual deprivation amblyopia and must be treated within the first weeks of life to prevent permanent, severe vision loss.
The approximate best-corrected visual acuity of a healthy full-term neonate at birth is:
Answer: 20/400–20/600
At birth, a full-term neonate has visual acuity of approximately 20/400 to 20/600 because the visual system is still immature.
The Worth 4-Dot test primarily assesses:
Answer: Binocular sensory fusion and suppression
The Worth 4-Dot test evaluates binocular sensory fusion and detects suppression or diplopia at distance and near.
Congenital (infantile) esotropia is typically characterized by:
Answer: Large, constant angle greater than 30 PD
Congenital (infantile) esotropia is typically characterized by a large, constant angle of deviation greater than 30 prism diopters present from birth or within the first 6 months.
Which refractive error is most closely associated with accommodative esotropia?
Answer: Hyperopia
Accommodative esotropia is most commonly associated with uncorrected hyperopia, as excessive accommodation drives convergence and causes esotropia.
