RC was derived from OCT data using a three-dimensional reconstruction system. Mean RC was assessed in concentric circles (RC I\u2013VI) with diameters of 1, 3, 6, 9, 12 and 15\u2009mm around the fovea, as well as in four orientations (RC S\/I\/N\/T).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 443 eyes were included in the analysis. The values from RC I to RC VI were 0.51\u00b10.19, 0.53\u00b10.19, 0.62\u00b10.19, 0.76\u00b10.23, 0.86\u00b10.23\u2009and 0.81\u00b10.18 10\n                      <jats:sup>\u22122<\/jats:sup>\n                      mm\n                      <jats:sup>\u22122<\/jats:sup>\n                      , respectively. RC I exhibited the smallest curvature, while RC V displayed the highest (p&lt;0.001). High myopia (HM) group demonstrated larger RC I and smaller RC III\/IV\/V\/VI compared with low myopia (LM) group (p&lt;0.01). Significant differences among RC S\/I\/N\/T were observed in HM group (pairwise comparison, p&lt;0.001), but not in LM group. Multiple regression analysis revealed that age, sex, corneal curvature radius and subfoveal choroidal thickness (SFCT) were associated factors with foveal RC, while age, SFCT and axial length (AL) were associated factors of peripheral RC.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>RC can quantitatively characterise retinal shape and the morphological changes induced by myopia.
