| Popis: | 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. [ Ophthalmic Surg Lasers Imaging Retina . 2019;50:e133–e139.] |
