Assessment of an Advanced Vision Screener in the Detection of Amblyopia in the Nebraska Pediatric Population.

Abstract

PURPOSE:

To determine the validity of the OPTEC 5500 vision screener (Stereo Optical Co., Inc., Chicago, IL) in assessing visual acuity and amblyopia in pediatric patients between the ages of 3 and 17 years by comparing it statistically to gold standard comprehensive ophthalmic examinations.

METHODS:

A cross-sectional study was conducted of 64 patients between the ages of 3 and 17 years who underwent a vision screening test at a pediatric ophthalmology office using the OPTEC 5500 vision screener, followed by traditional visual acuity testing via the Snellen or Lea optotypes. After data were collected, the results of the OPTEC 5500 vision screener were compared to the Snellen and Lea visual acuity tests and statistical analysis was subsequently performed for the right and left eyes separately. Patients were considered to have risk factors for amblyopia based on the American Association for Pediatric Ophthalmology and Strabismus referral criteria guidelines.

RESULTS:

The results of the OPTEC 5500 vision screener for the right eye of participants of all ages were a sensitivity of 77.4%, specificity of 100.0%, positive predictive value of 100.0%, negative predictive value of 50.0%, and accuracy of 81.5%. Results for the left eye were a sensitivity of 81.0%, specificity of 87.0%, positive predictive value of 91.9%, negative predictive value of 71.4%, and accuracy of 83.1%.

CONCLUSIONS:

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.].
