Background and purpose: Carefully interpreted photoscreen programs yield high predictive value and favorable sensitivity for amblyopia in pre-school children, but most require a long learning curve. The new PediaVision photoscreener appears to offer advantages and is evaluated in caparison with other established screening methods.
Methods: The Plus Optix S04 (PediaVision) computer-interpreted, infrared photoscreener was compared to digital physician-interpreted (Gateway DV-S20) photoscreening and patched Surround HOTV acuity testing in Kindergarten students.
Results: The estimated sensitivity and predictive value and speed of the objective photoscreeners exceeded visual acuity testing. The PediaVision photoscreener, in addition, allowed a practical range of referral refractive criteria to be determined and utilized.
Conclusion: The PlusOptix allows user-chosen, age-related, referral criteria and a quick, child friendly, photoscreening technique that should be ideal for many Kindergarten and preschool eye/vision screening programs.
