|Condition or disease||Intervention/treatment|
|Amblyopia Bilateral Hyperopia of Both Eyes Astigmatism Bilateral Accommodation Disorder||Diagnostic Test: objective pediatric vision screen "GCK glow fixation"|
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.
