概要	Purpose:To report the detection of retrobulbar blood vessel in the optical coherence tomography angiographic (OCTA) images of two eyes with pathologic myopia.Observations:Two eyes of 2 cases with pathologic myopia were examined by OCTA (RTVue XR Avanti, Optovue, and Cirrus 5000, Zeiss). Case 1 was a 64-year-old man, and Case 2 was a 65-year-old woman. In Case 1, the thickness of the subfoveal choroid was 38 μm and the sclera was 274 μm, and they were 17 μm and 214 μm, respectively, in Case 2. The axial length was 35.8 mm in Case 1 and 29.5 mm in Case 2. The choroidal vessels were clearly visible in the choriocapillary slab in both the RTVue and the Cirrus images. The vessels were visible in the area of the retinal pigment epithelial and choriocapillaris atrophy due to the pathologic myopia. The retrobulbar blood vessels temporal to fovea were seen in the OCTA images at the level of the outer aspect of the sclera in both cases. Cross sectional images of the retrobulbar blood vessel in both cases were observed under the sclera in serial scan images overlaid with blood flow.Conclusions:and Importance: These in situ images of the retrobulbar blood vessels that were obtained by OCTA was possible because of the thinness of the choroid and sclera and atrophy of the choriocapillaris in these eyes with pathologic myopia. We conclude that OCTA might have utility to study the retrobulbar vascular alterations in eyes with pathologic myopia.
