Optical coherence tomography angiography findings in retinal cavernous hemangioma: New cases and review of the literature

Abstract

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.
