The paired difference of spherical radius of curvature (in mm) in all the sectors (nasal, inferior, temporal, superior, central) at choroidal inner boundary (CIB) and choroidal outer boundary (COB) in different age categories. It also shows overall (union of all five sectors) paired difference of spherical radius of curvature at CIB and COB.

SD standard deviation, CI confidence interval; All measurements are in mm. Significant p values are highlighted in bold.
