    1. Diurnal variation of choriocapillaris vessel flow density in normal subjects measured using optical coherence tomography angiography

      Diurnal variation of choriocapillaris vessel flow density in normal subjects measured using optical coherence tomography angiography

      Background Vessel flow density (VFD) may provide important information regarding perfusion status. Diurnal variation in VFD of choriocapillaris has not been reported in literature. In the index study, optical coherence tomography angiography (OCTA) was used to assess the diurnal variation of the VFD in the choriocapillaris of subjects with no known ocular disease. Methods Fifty eyes with no known ocular disease (25 subjects) were included. OCTA images were acquired using AngioVue (Optovue, Fremont, CA, USA) at two different time points on a single day: 9:00 AM and 6:00 PM. Macular cube scan protocol (3 × 3 mm) centered on ...

    2. Evaluation of macular and peripapillary vessel flow density in eyes with no known pathology using optical coherence tomography angiography

      Evaluation of macular and peripapillary vessel flow density in eyes with no known pathology using optical coherence tomography angiography

      Purpose To assess normal vessel flow density (VFD) in macular and peripapillary regions of eyes with no known ocular pathology using optical coherence tomography angiography (OCTA). Methods AngioVue (Optovue, Fremont, CA, USA) was used to capture OCTA images. A 3 × 3 mm grid and a 4.5 × 4.5 mm grid was used to scan parafoveal and peripapillary regions, respectively. ReVue software was utilized to measure VFD in five sectors within the inner two circles of ETDRS grid in macular region and correlated to retinal thickness of same sectors. At optic disc, VFD was calculated in six sectors based on ...
