MedicalResearch: What are the main findings of the study?
Answer: Commercially available automated screening devices assess refractive risk factors, not amblyopia or strabismus, resulting in under-referral of affected children and over-referral of healthy children to pediatric eye care professionals. The Pediatric Vision Scanner is a binocular retinal birefringence scanner that directly detects strabismus and amblyopia by analyzing binocular scans for the presence or absence of birefringence, which is characteristic of steady, bifoveal fixation. We found that the Pediatric Vision Scanner outperformed an automated, refractive error screener (SureSight Autorefractor) in a cohort of 300 patients (2-6 years) tested in a pediatric ophthalmology setting. Compared to the SureSight, the Pediatric Vision Scanner had significantly higher sensitivity and higher specificity in the detection of strabismus and amblyopia. Continue reading
