光学相干体层成像术血管造影(OCTA)能够显示虹膜蔓状血管瘤的发展过程及其与正常微血管系统的相关性。该文作者对4例诊断为单侧虹膜蔓状血管瘤的患者进行OCTA特征性分析。结果:患者平均年龄50岁,临床和超声生物显微镜检查未发现虹膜或睫状体肿瘤。通过前节OCT,蔓状血管瘤部分可视。通过OCTA,能够发现血管瘤清晰呈现为直径 Optical coherence tomography angiography (OCTA) can demonstrate the development of iris-like hemangiomas and their association with the normal microvascular system. The authors performed OCTA characterization of four patients diagnosed with unilateral iris-like hemangiomas. Results: The average age of patients was 50 years. No iris or ciliary body tumors were found by clinical and ultrasound biomicroscopy. Through the anterior section of OCT, part of the hemangiomas visible. By OCTA, hemangiomas can be found clearly in diameter
