Reduced accommodation in children with Down syndrome

Invest Ophthalmol Vis Sci. 1993 Jun;34(7):2382-7.


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.
