Branching vascular networks (BVNs) and polypoidal lesions showing by OCT angiograms. The hyperreflective BVNs were primarily located at the choroid capillary level (a2, b2). BVNs were faint or absolutely fade out at the outer retinal level (a1, b1). The polypoidal lesion was a cluster of hyperreflective, medium or hyporeflective spots (red dashed circles in a2 and b2). On ICGA images, polypoidal lesions showed as clusters of hyperfluorescent spots (red dashed circles in a5 and b5) in connection to the ends of BVNs. The double lines in B scan OCT images of a3, a4, b3, and b4 indicated the layers exhibited in a1, a2, b1, and b2 respectively. (Yellow dashed line: BVN; Red dashed line: polypoidal lesion)
