Correlation between ocular biological parameters and cycloplegic refractive shift in pediatric myopia

Abstract:

AIM: To analyze the correlation between ocular biometric parameters and cycloplegic refractive shift (ΔSE) and to provide evidence for clinical decision-making regarding cycloplegic refraction in pediatric myopia management. METHODS: This retrospective study enrolled myopic patients aged 5-17y between July 2022 and November 2023. Data collected included age, gender, pre-cycloplegic spherical equivalent (SE1), axial length (AL), average corneal curvature (K), lens thickness (LT), anterior chamber depth (ACD), central corneal thickness (CCT), positive relative accommodation (PRA), negative relative accommodation (NRA), and post-cycloplegic spherical equivalent (SE2). Only right eyes were analyzed. Participants were divided into three groups by ΔSE: Group A (ΔSE≤0.25 D), Group B (0.25<ΔSE<0.75 D), and Group C (ΔSE≥0.75 D). Based on SE2, subjects were classified into pre-myopia (−0.50
