Purpose: The aim of this study is to compare the data obtained from two different optical coherence tomography (OCT) angiography devices. Materials and Methods: Thirty-three eyes of 18 patients without any systemic disorder who applied to our clinic for a routine eye examination were included in the study. All eyes were measured both with swept-source DRI OCT Triton (Topcon Inc, Tokyo, Japan) and AngioVue OCT (Optovue, Fremont, California) devices. Superficial vascular density, deep vascular density, and choriocapillaris vascular density were evaluated at 5 different points. The evaluation points were as follows: the central foveal area with a diameter of 1 mm and the temporal parafovea, superior parafovea, nasal parafovea, and inferior parafovea regions which are between 1-3 mm of the diameter. Results: 10 (55.6%) of the 18 volunteers included in the study were female and 8 (44.4%) were male. The best corrected visual acuity of Snellen was 20/20 in all eyes and the intraocular pressure measurements were all within normal limits. Statistically significant differences were found in the superficial vascular density measurements at 1 point, in the deep vascular density measurements at 4 points, and in the choriocapillaris vascular density measurements at 5 points (p
