Image: Within a few seconds after the screening, the children's vision screening device calculates a binocular visibility score based on the alignment of the fovea, and provides the clinician with a "pass" or "reference" result
A study published in the Journal of the American Association of Children's Ophthalmology and Strabismus showed that a handheld scanning device that can detect subtle eye dislocations can accurately identify whether a child has amblyopia (amblyopia)
Michael F.
Amblyopia is the impaired vision of one eye and the main cause of preventable monocular vision loss, affecting 3 out of every 100 children in the United States
In early childhood, our developing brain learns how to take images from each eye and merge them into a single image to produce vision
Children with amblyopia do not perform well in school, and their depth perception and fine motor skills (such as writing and other hand-eye coordination activities) are impaired
The treatment of amblyopia usually involves wearing an eye mask on healthy eyes to improve the vision of amblyopia
The working principle of this screening device is to evaluate the ability of the eyes to look at the same time
In this study, 300 children between the ages of 2 and 6 with no known eye diseases were recruited to the Kaiser Permanente Southern California Pediatric Clinic during a previously scheduled visit
Two non-ophthalmological research assistants trained in how to use the device screened each child and compared the results with the results of an eye exam performed by a pediatric ophthalmologist who did not know the results of the device
"In the hands of a well-trained user, it takes 28 seconds for the child to sit down, take the test, and record the results-if the child cooperates-this is an important consideration for adopting this method in a busy pediatric care environment
A key limitation of the study is that the device has not been compared with currently available photo screening devices
In contrast, children's vision scanners detect the presence of amblyopia, not the risk factors for amblyopia, which may lead to fewer unnecessary referrals to the pediatric ophthalmologist
The children's vision screen tested in this study is a prototype of Blinq
The clinical trial identification is NCT02536963
