Optical Coherence Tomography Angiography Findings in Retinal Cavernous Hemangioma: New Cases and Review of the Literature.

Introduction. - Retinal cavernous hemangioma (RCH) is a rare retinal vascular disease characterized by grape-like clusters of saccular aneurysms, usually unilateral, asymptomatic and non-progressive. The diagnosis is made by multimodal imaging including conventional fluorescein angiography (FA). The recent introduction of swept source optical coherence tomography angiography (SS-OCTA) has allowed new insight into vascular diseases, allowing non-invasive, more precise visualization of retinal and choroidal blood flow, and represents a possible alternative to FA. Methods. - We herein describe two cases of RCH with multimodal imaging, including SS-OCTA, and compare our findings with those previously described. Results. - On OCTA, the presence of a draining vessel, a reduction in flow signal in the SCP and DCP, and a fluid level can be observed. Conclusion. - These OCTA signs are in accordance with those described on conventional fluorescein angiography, allowing this invasive exam to be avoided in typical cases.
