Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
