ABSTRACT: 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 comparison with other established screening methods.
Methods: The PlusOptix 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 photscreener, in addition, allowed a practical range of referral refractive criteria to be determined and utilized (see below table).
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.
