[Results of optical coherence tomography angiography in choroidal melanoma].

Changes in angioarchitectonics in the area of CM localization can be detected at a thickness of 1 mm, and the tumor's own vasculature - starting with a thickness of 1.4 mm. The vascular pattern at the level of the deep choroidal layers best corresponds to the reported angiographic picture and patterns of vasculogenic mimicry.
