Abstract In children with Down syndrome (DS) development of visual, motor and cognitive functions is atypical. It unknown whether the visual impairments in DS aggravate their lag development. Visual impairment developmental lags adaptive behaviour executive were assessed 104 DS, 2–16 years, by comparing behaviour, acuity (distant near) scores against published age-matched norm typically develop...

Screening for impaired distant visual acuity was one component of a controlled trial of multiphasic screening in middle age carried out in two general practices. The prevalence of impaired visual acuity (6/18 or worse in the better eye) at the initial screening in 1967 was 9.6% overall, ranging from 5.9% in people aged 40-49 years to 16.3% in those aged over 60. The question "Do you have diffic...

BACKGROUND To screen for visual impairment in Malaysian preschool children. METHODS Visual screening was conducted in 400 preschool children aged 4 to 6 years. The screening involved two basic procedures; the distant visual acuity test using the Sheridan Gardiner chart and the depth perception test using the Langs stereoacuity test. Criteria for referral were a visual acuity of 6/12 or less i...

to facilitate a comprehensive whole population visual acuity screening, a 1-meter vision screener “e” chart was prepared to be used in the person-by-person household visual acuity examination by non-expert health workers. the chart is designed to be used in measuring visual acuity from a distance of one meter. the scaling is in terms of-log mar (logarithm of minimum angle of resolution) with a ...
