Retinal hypoperfusion detected by wide-field optical coherence tomographic angiography in a case of retinal racemose hemangioma.

Wide-field OCTA detected sparse retinal capillaries, which were not well illustrated by FA, in a patient with RRH. This indicates the presence of low-grade retinal hypoperfusion caused by altered retinal hemodynamics, potentially leading to ischemia-related retinal disorders during a prolonged course, in patients with clinically quiescent RRH.
