Abstract
Objectives:This study was designed to evaluate macular perfusion in a healthy pediatric population using optical coherence tomography angiography (OCTA).Methods:Fifty-three eyes of 30 healthy children (20 boys and 10 girls) were included in this prospective, cross-sectional study. Age, gender, foveal thickness (FT), superficial foveal avascular zone area (FAZs), deep foveal avascular zone area (FAZd), superficial capillary plexus flow area (SCP), deep capillary plexus flow area (DCP), choriocapillaris flow area (CC), vascular density in the SCP (VDs), vascular density in the DCP (VDd), and subfoveal choroidal thickness (SFCT) were evaluated.Results:The mean age was 12.0±4.0 years (range: 6-15 years). Gender did not have a statistically significant influence on the FAZs or FAZd. However, there was a positive correlation between the CC and age (r=0.31; p=0.025). The FAZs and FAZd were negatively correlated with the FT (p<0.001). The VDd was positively correlated with the FT (p=0.03) and was negatively correlated with the FAZd (p=0.019).Conclusion:The present study determined normative data of OCTA parameters in healthy children and provides useful insight into the relationship between age, macular microvascular networks, and the FAZ.
