Handheld Device Screens for Amblyopia in Young Children
Validation study shows 100 percent sensitivity, 85 percent specificity, median acquisition time of 28 seconds for Pediatric Vision Scanner
FRIDAY, Oct. 1, 2021 (HealthDay News) – The Pediatric Vision Scanner (PVS) has high sensitivity for amblyopia in a pediatric population of children aged 24 to 72 months, according to a study recently published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus.
Shaival Shah, M.D., from the Southern California Permanente Medical Group in Tustin, and colleagues screened 300 eligible children aged 24 to 72 months with no known eye conditions for amblyopia and strabismus using the PVS in a prospective study. A comprehensive eye examination was then performed by a pediatric ophthalmologist masked to PVS screening results.
The researchers found that six children (2 percent) had amblyopia and/or strabismus based on the gold standard eye examination. All six cases were detected by the PVS, yielding sensitivity of 100 percent. In addition, 45 children (15 percent) who had normal ophthalmic findings were referred by the PVS, yielding specificity of 85 percent. For the PVS, the median acquisition time was 28 seconds.
"In the hands of a trained user, it takes 28 seconds to sit the child down, perform the test, and record the results -- provided that the child cooperates -- which is an important consideration for its adoption in busy pediatric care settings," Shah said in a statement.
The study was funded in part by Rebiscan, the manufacturer of the Pediatric Vision Scanner.
