Pediatric Myopia and Retinal Microvascular Density: An OCTA evaluation

Study Design:Prospective observational study.
Purpose:To evaluate retinal microvascular alterations in pediatric myopic eyes by OCTA&determine association with axial length&refractive error.
Methods:Myopic patients aged5–18years with sph equivalent< -0.50Dunderwent cycloplegic refraction,optical biometry,fovea-centered SD-OCTA scans Octava software segmented retinal vasculature into SCP,ICP,DCP for vessel density analysis
Result:32eyes studied(mean age13.06±4.02 years;mean AL24.93±1.39 mm;mean SE -3.87±2.79D).Retinal vessel density progressively decreased from SCP to DCP.Increased AL had significant negative correlation with microvascular density,especially in the DCP, &was the strongest independent predictor of reduced vascular density
Conclusion:AL elongation in pediatric myopia is associated with significant reduction in retinal microvascular density mainly in DCP
OCTA may serve as a noninvasive tool for early detection&monitoring of retinal microvascular changes in pediatric myopia
