The Prevalence and Form of CVI in Angelman Syndrome

Summary of Dr. Erickson’s Study
There is good reason to believe that many individuals with AS have cortical visual impairment (CVI). This is a specific type of vision impairment that may affect balance, walking, communication and behavior.

This study, will accomplish three things:

1. Estimate the number of individuals with AS that have CVI
2. Assess the severity of CVI in individuals with AS
3. Determine whether CVI has an effect on communication in children with AS

Dr. Erickson believes that in identifying and understanding CVI in individuals with AS, it will allow for early intervention, which may improve communication and behavior outcomes.
