Abstract
Purpose: Children with Down syndrome (DS) and cerebral palsy (CP) often have reduced visual acuity (VA). This study assessed VA and low contrast acuity (LCA) with Lea symbols in DS and CP populations to explore whether LCA measures provide useful additional information about visual performance. VA and LCA were also measured from a large group of typically developing children. Methods: High contrast VA and LCA performance was measured monocularly using crowded Lea symbols on 45 children with CP (mean age 11.8+/-4years), 44 with DS (mean age 10.5+/-3years) and 211 controls (mean age 11.4+/-3years). Refractive status was confirmed with cycloplegic retinoscopy. Results: DS and CP groups had significantly lower acuities than controls at all contrasts (p
