Neurological and ocular abnormalities in patients with Down's syndrome

Richard A. Armstrong, Helen Carroll

Research output: Contribution to specialist publication or newspaperArticle


Down's syndrome, first described by J. Langdon Down in 1866, is the most common chromosomal abnormality to occur in the human population. Its incidence is approximately 1/650 of all births although the risk of having a Down's child increases markedly with the age of the mother. It occurs with equal frequency in all racial groups. The risk to a mother 16-26 years old is 1 in 1,300 but the risk increases to 1 in 30 for a mother 45-47 years old. The life expectancy of people with Down's syndrome has risen since the 1920s and many individuals are now living to the 5th decade or beyond. Consequently optometrists are increasingly likley to see Down's patients of all ages in the practice.
