Abstract

PURPOSE. To examine the accommodative accuracy and amplitude in children with Down syndrome. Accommodation is usually assumed to be good in children and is rarely measured. METHODS. A dynamic retinoscopy technique was developed that allows rapid and reliable measures of accuracy and amplitude of accommodation in infants and children. RESULTS. Use of the dynamic technique with a small sample of schoolchildren with Down syndrome shows that 80% have reduced amplitude of accommodation, in comparison to a control group of developmentally normal children. CONCLUSIONS. Optometric management of children with Down syndrome should include consideration of accommodation.
