Changes in choriocapillaris blood flow density and associated factors affecting axial elongation in Chinese children and adolescents with mild to moderate myopia: a cross-sectional study.

ABSTRACT:

Background

To investigate changes in choriocapillaris blood flow density (CFD) and identify factors influencing axial elongation in Chinese children and adolescents with mild to moderate myopia.

Methods

A hospital-based cross-sectional study was conducted. A total of 288 participants aged 8 to 15 years were recruited from Tianjin Eye Hospital, including 186 children and adolescents with myopia and 102 age-matched participants without refractive error who served as the control group. Based on cycloplegic spherical equivalent (SE), the myopic participants were further categorized into moderate and mild myopia groups. Refractive power was determined through refraction tests, while various parameters-including axial length (AL) and choriocapillaris flow density (CFD)-were obtain
