IOLMaster 700 was used to acquire ocular biometry data, and RPR was measured using multispectral refraction topography. Refraction difference values (RDVs) were used to describe the RPR and included the total defocus (TRDV), defocus at 0° to 15° (RDV15), 15° to 30° (RDV15-30), 30° to 45° (RDV30-45), and 45° to 53° (RDV45-53) eccentricities, and superior (RDV-S), inferior (RDV-I), temporal (RDV-T), and nasal (RDV-N) quadrants.<h4>ResuFrontiers in medicine1711559https://www.ebi.ac.uk/biostudies/studies/S-EPMC12907144biostudies-literatureQuantitative assessment of relative peripheral refraction in children with different refractive statuses and its associations with ocular biometry.PMC12907144Liu YYe CShang JZhu XQu XWang YXu YfalseQuantitative assessment of relative peripheral refraction in children with different refractive statuses and its associations with ocular biometry.<h4>Background</h4>This study aimed to evaluate the distribution of relative peripheral refraction (RPR) and its relationship with ocular biometry in Chinese children of different refractive statuses.<h4>Methods</h4>This study included 309 participants aged 4 to 14 years who were divided into three groups based on refraction: hyperopia, emmetropia, and myopia.
