Chien JL, et al. - The goal of this study is to depict optical coherence tomography angiography (OCTA) features of iris racemose hemangioma. The outcome suggests that the optical coherence tomography angiography is a noninvasive vascular imaging modality that clearly describes the looping course of iris racemose hemangioma. Optical coherence tomography angiography described fine details of radial iris vessels, not distinct on intravenous fluorescein angiography.
