Correlation of the macular microvasculature to the axial length in pediatric patients with high axial refractive errors

Aims To compare the vascular density (VD) of the macular superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC), and the foveal avascular zone (FAZ) among high hyperopic, high myopic, and emmetropic children using optical coherence tomography angiography (OCTA).

Description
Summary:Aims To compare the vascular density (VD) of the macular superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC), and the foveal avascular zone (FAZ) among high hyperopic, high myopic, and emmetropic children using optical coherence tomography angiography (OCTA). Methods This was a cross sectional comparative study of otherwise healthy children with different refractive errors. Patients were recruited from Cairo University Children’s Hospital. OCTA imaging was performed using the RTVue XR Avanti device with AngioVue software. Both the 3 × 3 and 6 × 6 mm macular scans were utilized. Automated measurements were obtained from the built-in machine software. Axial length (AL) measurements were done using Lenstar LS 900 optical biometer. Results Ninety eyes from 51 healthy children were included. Among high myopes, there was significant thinning of the parafovea ( p
