We describe features of a circumscribed choroidal hemangioma (CCH) treated with photodynamic therapy (PDT) by means of optical coherence tomography angiography (OCT-A). A 40-year-old man had a complaint of decreasing visual acuity in his left eye for 10 days. A diagnosis of CCH was confirmed by fundus examination, fluorescein angiography, and indocyanine green angiography. An OCT-A study of choroidal lesion before and after PDT was carried out. Segmented en face OCT-A of CCH showed multiple irregular connected vascular channels with hyperflow and a capillary-like lesion. Absent and/or reduced intrachannel flow in most of the intratumoral vessels was shown by OCT-A soon after treatment (2 days), with normalization of vascular flow 7 days and 1 month after PDT. OCT-A was able to noninvasively visualize intrinsic vasculature of CCH showing vascular remodeling after PDT.
