N2 - BACKGROUND AND OBJECTIVE: To investigate choriocapillary blood flow in myopic eyes using optical coherence tomography angiography. PATIENTS AND METHODS: Seventy-eight myopic and 79 age-matched healthy eyes were included in this study, with myopia defined as a spherical equivalent refraction (SER) between –1 diopters (D) and –6 D. Quantitative measurements of the choriocapillaris were obtained using the Avanti RTVue XR with AngioVue. Choroidal thickness (CT) was assessed using the single-line enhanced high-definition scan of the same device. RESULTS: CT correlated positively with SER (P = .017) and negatively with bulbus axial length (AL) (P = .180). Subfoveal choriocapillary blood flow did not show any significant correlation with any of the parameters SER, AL, or CT (P = .798, P = .269, and P = .820, respectively). The mean flow signal of the myopic group did not differ significantly from the mean flow signal of the emmetropic control group (P = .266). CONCLUSION: Choriocapillary blood flow seems to retain a constant level with increasing physiological myopia.
