    Axial length to corneal curvature radius ratio is negatively correlated with choroidal blood flow in myopic children by Yurong Ye, Zizhong Hu, Na Su, Yeyu Shen, Songtao Yuan

    Published 2025-01-01
    “…BackgroundThe pathophysiologic mechanisms underlying early-onset myopia remain unclear; in this study, we investigate the pathogenesis by examining the interrelationships between axial length to corneal curvature radius ratio (AL/CR) and choroidal blood flow.MethodsThis cross-sectional study included 202 eyes from myopic children, categorized into 141 eyes with mild myopia, 47 eyes with moderate myopia, and 14 eyes with high myopia. Optical coherence tomography angiography (OCTA) was used to measure choroidal blood flow perfusion within a 6 mm × 6 mm area of the macular region, divided into nine subareas based on ETDRS partitioning: macular fovea, nasal side 1, superior 1, temporal side 1, inferior 1, nasal side 2, superior 2, temporal side 2, and inferior 2. …”
