Purpose : Amblyopia, defined as a functional reduction in the visual acuity of an eye caused by disuse or misuse during the critical period of visual development, is the most common visual deficit in children with a prevalence of 4%. OPTEC 5500 Vision Tester (OVT) is widely available in pediatric medical practices for visual screening, due to inexpensiveness and ease of use. No studies have been conducted to ascertain the validity of this device in the pediatric population for the detection of amblyopic risk factors. The aim of this cross-sectional study was to determine the validity of the OPTEC Vision Screener in detecting refractive errors and amblyopia in pediatric patients age 3-17 years, by comparing it to the gold standard comprehensive ophthalmic examinations.

Methods : A cross-sectional study of sixty-four subjects, ages 3-17 underwent a vision-screening test using the OPTEC vision screener, followed by the traditional visual acuity testing via the Snellen or Lea optotypes. After data was collected the results of the OPTEC were compared to the Snellen and Lea visual acuity tests (gold standard), and then statistical analysis was performed for the right and left eyes separately. Patients were considered to have amblyopic risk factors based on the American Association of Pediatric Ophthalmology and Strabismus (AAPOS) referral criteria guidelines.

Results : The overall results of the OPTEC study for participants of all ages were as follows: Right Eye- sensitivity: 77.4%, specificity: 100.0%, positive predictive value: 100.0%, negative predictive value: 50.0%, and accuracy: 81.5%. Left Eye- sensitivity: 81.0%, specificity: 87.0%, positive predictive value: 91.9%, negative predictive value: 71.4%, and accuracy: 83.1%.

Conclusions : The OPTEC 5500 is a vision screening device that employs “E” or Snellen optotypes projected to simulate distance visual acuity inside a self-contained housing. While specificity was acceptable, sensitivity of OVT were below average of other available devices; and exhibited some of the weakness the device. We need to continue to explore better options for pediatric vision screening devices.
