The Brückner test helps detect amblyopia and strabismus by:
Answer: Comparing the brightness of the red reflex in both eyes simultaneously
The Brückner test compares the simultaneous red reflex brightness in both eyes — a brighter or lighter reflex in one eye suggests strabismus or amblyopia.
The cover-uncover test specifically detects:
Answer: Manifest strabismus (tropia)
The cover-uncover test detects manifest strabismus (tropia) by observing movement of the uncovered eye when the fellow eye is covered.
Anisometropic amblyopia most commonly results from:
Answer: Significantly unequal refractive errors between the two eyes
Anisometropic amblyopia results from significantly unequal refractive errors between the two eyes, causing the more ametropic eye to receive a chronically blurred retinal image.
Most pediatric vision screening guidelines recommend formal optotype visual acuity testing beginning at age:
Answer: 3 years
Most guidelines recommend formal optotype visual acuity testing beginning at age 3 years, when children can reliably cooperate with letter or symbol chart testing.
Which finding during pediatric vision screening warrants immediate ophthalmology referral?
Answer: White pupillary reflex (leukocoria)
Leukocoria (white pupillary reflex) is a red flag that may indicate retinoblastoma, congenital cataract, or other serious pathology requiring immediate evaluation.
Most pediatric vision screening guidelines recommend referral if visual acuity is worse than which threshold in children aged 3–5 years?
Answer: 20/40 in either eye
Most guidelines recommend referral if best-corrected visual acuity is worse than 20/40 in either eye in children aged 3–5 years.
