Retinal curvature in Chinese children with myopia measured by ultra-widefield swept-source optical coherence tomography.

RC can quantitatively characterise retinal shape and the morphological changes induced by myopia. Myopia progression results in a bulging macular retina accompanied by a flattening peripheral retina in children, and also increases the irregularity among the four quadrants. Age, AL and SFCT are associated factors of RC.
