Pediatric photoscreeners in high risk patients 2012: a comparison study of Plusoptix, Iscreen and SPOT.

Background: New photoscreening models promise to detect amblyopia risk factors early in hopes of reducing permanent pediatric monocular and binocular vision impairment. The 3 commercially available interpreted photoscreeners had not yet been compared.

Methods: This is a prospective, observational screening study following AAPOS guidelines on pediatric patients with and without developmental delays.

Predictive value from pediatrician plusoptix screening: impact of refraction and binocular alignment.

Background: The positive predictive value (PPV) of conventional preschool acuity screening is about 50% whereas previous Polaroid photoscreening with experienced interpretation can achieve PPV greater than 85%. The Plusoptix photoscreener has immediate computer interpretation and a CPT code available to pediatricians.

Methods: Two Plusoptix SO9 were used in two pediatric group practices with previously validated refractive criteria and new manufacturer's binocular alignment criteria.
