Résumé
Background
This study aims to compare the parafoveal retinal microcirculation in children with severe adenotonsillar hypertrophy (ATH) and healthy controls using optical coherence tomography angiography (OCTA).
Methods
Sixty-six eyes (31 children with ATH and 35 healthy controls) were analyzed. Parafoveal OCTA images (6 × 6 mm) were obtained using a swept-source OCTA device (DRI OCT Triton; Topcon Corporation, Tokyo, Japan). Vessel density (VD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) was measured in the central and four parafoveal quadrants. The foveal avascular zone (FAZ) area was also measured in both plexuses.
