PURPOSE: New objective photoscreeners are emerging with encouraging national guidelines and pediatric providers can be reimbursed for photoscreening.METHODS: Nine objective screeners were applied to two emmetropic subjects with or without known power contact lenses to induce spherical and cylindrical anisometropia close to American Association for Pediatric Ophthalmology and Strabismus (AAPOS) thresholds.RESULTS: The screeners produced near linear pupil crescents and estimated refractions for induced anisometropia. Most performed well with AAPOS 2003 validation; however, the iPhone (Apple, Cupertino, CA) was too sensitive, whereas the remote autorefractors using Vision in Preschoolers Study criteria were less sensitive.CONCLUSIONS: The new, interpreted objective screeners appear valid for detection of anismetropia.
