Hyperopia Detection GCK With Glow Fixation
Study Details
Study Description
Brief Summary
"GoCheck Kids" has added to its iPhone 7+ smart phone with flash concentrator a non-accommodating glow box fixation target. In pediatric eye patients, the "GCK" with glow box is compared to cycloplegic refraction as well as School Bus Accommodation-relaxing skiascopy, "2WIN" photoscreener and "Retinomax."

Detailed Description
Patients undergoing comprehensive pediatric eye exam were screened with "GoCheck Kids" iPhone 7+ flash concentrated photoscreener with new, non-accommodating glow fixation target are well as "Adaptica 2WIN" photoscreener and "Retinomax" auto refraction all without drops before cycloplegia examination.
Reason for examination, visual acuity, ocular alignment and degree of amblyopia were specifically noted.
Refractive amblyopia risk factors utilizing "AAPOS 2003" and "AAPOS 2013" uniform guidelines were used to validate each screening method.
Patients for whom cycloplegia exam yielded at least 0.5 diopters hyperopia were compared to determine the ability of each screening tool to detect hyperopia.

Outcome Measures
Primary Outcome Measures
- 2003 and 2013 AAPOS Uniform Amblyopia Risk Factor (ARF) prevalence [1 week]
