Early retinal and choroidal changes in the macula region associated with axial length in myopic children and adolescents based on swept-source OCTA

Axial elongation in young individuals with myopia is associated with specific early microvascular and structural alterations that can be detected using ssOCTA. Deep retinal vascular attenuation and choroidal volumetric loss (CVV, CSV) represent the most prominent hemodynamic changes linked to AL, showing regional variations within the macula. These findings highlight early structural and hemodynamic changes associated with myopic progression in pediatric and juvenile populations.
