Abstract
PURPOSE
The blinq (Rebion Inc) is a new screening device designed to directly detect amblyopia and strabismus rather than amblyopia risk factors. We performed an independent assessment of the effectiveness of the blinq in detecting amblyopia and strabismus.
DESIGN
Prospective clinical validity analysis of a screening device based on sensitivity and specificity.
METHODS
Children presenting for examination in the pediatric ophthalmology clinic underwent screening with the blinq before examination by a pediatric ophthalmologist blinded to the screening results. Results of the blinq and examination findings of strabismus or amblyopia were compared.
RESULTS
In our cohort of 267 children with an average age of 6.3 years, the sensitivity of the blinq to detect amblyopia or any constant strabismus was 87.5% (78.2%-93.8%) and specificity was 51.3% (43.9%-58.7%). Using the previously described "appropriate referral gold standard" criteria, including children with intermittent strabismus and high refractive error, the sensitivity increased to 91.3% and the specificity to 63.2%. We found a high number of children (44 [16%]) upon whom the blinq timed out and were included as automatic referrals.
CONCLUSIONS
Our results support use of the blinq as a screening device to detect amblyopia and strabismus in children.
