  • Title: [Behavioral determination of visual acuity in 1-to-4-year-old children].
    Author: Heersema DJ, van Hof-van Duin J.
    Journal: Tijdschr Kindergeneeskd; 1989 Dec; 57(6):210-4. PubMed ID: 2617508.
    Abstract:
    Visual acuity was assessed in 210 children aged 1 to 4 years using the Acuity card method. Visual acuity is expressed in minutes of arc, indicating the minimal angle for separate perception of two lines. Binocular visual acuity showed a gradual growth from 1.8 to 0.9 min, arc and monocular visual acuity from 1.7 to 1 min. arc during this age period. Adult values of 0.65 min. arc(binocular) and 0.70 (monocular) were not yet reached at 4 years of age. Age norms for visual acuity in children from 1 to 4 years of age were determined. The success rate for binocular visual acuity assessment was 99.5% at all ages and increased for monocular acuity assessment from 50% in the 1 to 2 year old to 100% in the 4 year olds. Acuity assessment was fast (test time 3.3 and 2.0 minutes for assessment of binocular and monocular acuity respectively). The inter-observer reliability of the binocular assessment in the same child was high.
