dc.description.abstractPurpose: To evaluate the Canon CP?TX1 camera as a screening tool for ARFs in a pediatric population and estimate the prevalence of ARFs. Methods: In a pediatric outpatient space, largely in the immunization clinic, after obtaining parental consent, we encouraged children to be photographed from a distance of 5 feet in a dim room by using a CP?TX1 camera with the red?eye reduction feature off. Based on the captured red reflex, children were labeled as normal (symmetrical red reflexes in the two eyes, with no visible crescents); all others were considered as abnormal or positive for ARFs. All photographed children were assessed by an optometrist/refractionist for VA by age?appropriate methods. Data were entered into a 2 � 2 contingency table on statpages.org, and diagnostic indices were calculated with 95%CI. Results: With a sample of 262 children, we obtained a sensitivity of 0.82, a specificity of 0.98, a positive predictive value of 0.92, a negative predictive value of 0.94, a positive likelihood ratio of 41.06, a negative likelihood ratio of 0.17, and a prevalence of 0.24 for ARFs. Conclusion: CP?TX1 performed well as a screening tool to identify ARFs in children. Placing such a camera in an immunization clinic offers a chance to identify children with ARFs at a time when amblyopia is eminently reversible.en_US
