Use of the Spot Vision Screener for patients with developmental disability

Purpose To determine whether the Spot Vision Screener effectively detects amblyopia risk factors (ARFs) in patients with developmental disability using the 2013 guidelines of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). Methods Children with developmental disability presenting for complete pediatric ophthalmologic examination were prospectively enrolled between June 2012 and March 2016. The following data were analyzed: presence of ARFs according to the AAPOS guidelines, refraction, eye alignment, and other ocular pathology. Results A total of 100 children (average age, 5.7 years; range, 2.2- 9.2 years) were included. The prevalence of ARFs in this cohort was 38%. The sensitivity of the Spot Vision Screener in detecting amblyopia risk factors was 84%; the specificity, 62%. The positive predictive value was 58%; the negative predictive value, 86%. Conclusions In our study cohort the Spot Vision Screener provided good sensitivity and adequate specificity for a screening examination. Automated screeners may be useful in screening children with developmental disability.
