- Abstract
Background: To measure the repeatability of foveal avascular zone (FAZ) area, vessel density (VD), and flow area using AngioVue Analytics optical coherence tomography angiography (OCTA) in the overall and different age groups of the Turkish population. Materials and Methods: This study included 100 eyes of 100 healthy subjects (54 females; mean age: 43.2±15.2 years). They were divided into five age groups- 20-29, 30-39, 40-49, 50-59, and >60 years- with 20 subjects each. The optical disk region and macula were imaged thrice using a 4.5x4.5 mm and 3x3 mm scan, respectively. Intraclass correlation coefficient (ICC) and coefficient of variation (CV) analyses were used to evaluate repeatability. Results: CV and ICC for the FAZ area were 2.96% and 0.990, respectively. ICC values of entire image VD of superficial capillary plexus (SCP) and deep capillary plexus (DCP) were 0.828 and 0.842, respectively. CV and ICV for peripapillary VD were 2.32% and 0.990, respectively. ICC was 0.865 for the choriocapillaris flow area. CV values of different age groups showed no statistical differences, except for the FAZ area. Conclusion: OCTA measurements of the FAZ area, VDs of the SCP, DCP, and optic nerve, and the choriocapillaris flow area showed relatively good overall repeatability. Repeatability results of different age groups should guide the optimal use of OCTA.
