The Handy Eye Chart™ uses optotypes consisting of hand gesture symbols instead of letters, and children can use their own hands to replicate the gesture to indicate recognition of the optotypes. Previous research has shown that the chart is a valid test of visual acuity in children ages 6 to 18. Now, researchers are embarking on a research strategy to modify the chart for use in young children ages 2 to 5. The isolated optotypes will be presented using an ipad application, that will simultaneously present the optotypes and record the response data. Granular data can then be exported to a standard spreadsheet for analysis. Once the current phase of the research is complete, the iPad application will be modified and made available for use by parents, schools and health care professionals.
There are many children who cannot be tested with existing visual acuity charts including the very young, non-verbal, non-English speaking or developmentally challenged children. Atlantic Pediatric Device Consortium (APDC) has provided funding for the iPad application including software coding and graphic art.
