Purpose To investigate rapid changes in axial length (AL) and regional changes in choroidal thickness (ChT) and the choroidal vessel index (CVI) in myopic children with myopia caused by optical defocus. Methods Sixty‐two eyes of 31 children wearing Diverse Segments Defocus Optimization (DSDO) spectacle lenses and 58 eyes of 29 children wearing single‐vision spectacle lenses (SVL) were included. All participants were fully corrected and evaluated before and immediately after 30 min of reading. ChT and CVI were measured …
