To elucidate the development of the choroid and retina in children, and to explore changes in these during myopic shift.
A total of 118 children aged 7 to 12 years participated in this 1-year longitudinal study.
Children underwent several examinations at baseline and follow-up, including cycloplegic refraction, axial length measurement, and swept-source optical coherence tomography.
Thickness changes in the choroid and retina were compared among children with or without myopic shift.
