Introduction: Photoscreening allows community based vision screening programs to reach large numbers of children. Repeat photoscreening is recommended to maximize the chance of detecting amblyogenic risk factors. This study is the first to track a cohort of children who underwent yearly photoscreening over a 3-year time period.

Methods: Children ages 18 months-11 years were screened yearly at their school as part of a community vision screening program using the SPOT vision screener between 9/2015-9/2017. Data collected each year at the screening included age, gender, whether the child passed or was referred, and referral reason. Referral criteria adhered to published guidelines by the AAPOS Vision Screening Committee.

Results: Over 3 years, 799 screenings were performed. 285 children underwent repeat annual screening (671 screenings) of which 26 children were referred (9.1%). Of those referred, nearly half (42.3%) passed the first year but failed a subsequent screening.  The average age of children who passed screening one year and were referred the next was 3 years.

Discussion: In this cohort, annual screening over a 3 year time period showed that almost half of all children referred would have passed an earlier screening but failed a subsequent screening. The average age of these children was 3 years, which is an age shown to be more responsive to amblyopia treatment.

Conclusion: These results support policy statements recommending yearly repeat vision screening of children in the amblyogenic age group. Further studies are needed to identify the positive predictive value of repeat screening.
