- Registration Number
- NCT03668067
- Lead Sponsor
- Alaska Blind Child Discovery
- Brief Summary
Pediatric eye patients receive infrared photoscreener screening and skiascopy as a part of routine examination to compare ability to detect amblyopia risk factors.
- Detailed Description
Patients: Pediatric eye and adult strabismus patients undergoing routine examinations in a private ophthalmology practice.
Interventions: Infrared photoscreener / remote autorefractor such as 2 Winner (2WIN) ("Adaptica" - Padova, Italy) without and with infrared corneal reflex occluder. Child-friendly skiascopy before and after cycloplegic refraction.
Outcome: Amblyopia Risk Factors from comprehensive eye exam including refraction and strabismus.
Risk factors defined by American Association for Pediatric Ophthalmology and Strabismus (AAPOS) 2003 and 2013 guidelines.
\*\*Please note that 2 Winner has nothing to do with actual device, but was required by the Clinical Trials Web entry.\*\*

- Primary Outcome Measures
Name Time Method Amblyopia Risk Factor (refractive error and/or strabismus) 2 hours or less: Screening and Gold Standard Exam performed the same day, usually within the same hour. Whether pre-defined, age-related risk factor is present. AAPOS has published standard levels of these refractive errors or binocular misalignment that render a child at risk of developing sight-threatening amblyopia.
