This report demonstrates the blood flow pattern in a case of choroidal hemangioma (CH) using swept-source-optical coherence tomography angiography (SS-OCTA). Fluorescein angiography, SS-OCT, and SS-OCTA images of a patient with CH were obtained using a standard protocol. The internal vascular pattern of the tumor was identified on both OCT and OCTA. Dark areas were identified in the CH. These were interspersed between areas of visible blood flow, as imaged on SS-OCTA. Peripheral vascular arcades were also identified within the tumor. SS-OCTA should be evaluated as an imaging tool to study the blood flow within choroidal tumors.
本报告展示了使用扫频源光学相干断层扫描血管造影(SS-OCTA)对脉络膜血管瘤(CH)病例的血流模式。采用标准方案获取了一名CH患者的荧光素血管造影、SS-OCT和SS-OCTA图像。在OCT和OCTA上均识别出了肿瘤的内部血管模式。在CH中发现了暗区。如SS-OCTA所成像的那样,这些暗区散布在可见血流区域之间。在肿瘤内还识别出了周边血管弓。SS-OCTA应作为一种成像工具进行评估,以研究脉络膜肿瘤内的血流情况。
