Although the specificity and positive predictive value were acceptable, the sensitivity and negative predictive value of the OPTEC 5500 vision screener were below average when compared to other available devices, exhibiting some of the weaknesses of the device. Additional studies of the OPTEC 5500 vision screener with a larger population are necessary to assess the device in the general pediatric population, such as in general pediatric clinics and public schools. Additionally, other options for pediatric vision screening devices should be explored. [J Pediatr Ophthalmol Strabismus. 2018;55(3):189-193.].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
