In the current issue of JAMA Ophthalmology, Jost and colleagues1 present further validity testing of the Pediatric Vision Scanner, which assesses binocular retinal birefringence as a method for detecting abnormal binocularity associated with strabismus and/or amblyopia. The novel technology was developed 15 years ago by David Hunter, MD, PhD, and David Guyton, MD, and has recently become available as a portable unit that can be used for screening children in a medical office or in a school setting.2
