This document discusses several special populations including children with cerebral palsy, Down syndrome, learning disabilities, and fragile X syndrome. It provides information on the definition, etiology, prevalence/incidence, physical and visual characteristics of each population. For cerebral palsy, it discusses the classifications, refractive characteristics, binocular vision issues, and tips for interacting with patients. For Down syndrome, it covers the definition, etiology, prevalence, physical traits, and refractive errors. It also provides updates on research related to accommodative dysfunction, bifocals, and biometric measurements in Down syndrome patients. Finally, it introduces fragile X syndrome by defining it and discussing its etiology and prevalence.

Down Syndrome
From: http://www.ndss.org/aboutds/aboutds.html#Down
Children with Down syndrome have been included in regular academic
classrooms in schools across the country. In some instances they are
integrated into specific courses, while in other situations students are
fully included in the regular classroom for all subjects. The degree of
mainstreaming is based in the abilities of the individual; but the trend is
for full inclusion in the social and educational life of the community.
