相干光层析血管成像术（OCTA）自问世以来，以其快捷无创获取眼底血流信息的优势得到广泛应用，并在诸多眼底疾病的诊断和随诊中表现出巨大临床价值。息肉状脉络膜血管病变（PCV）是一种以脉络膜毛细血管末端息肉样膨大及异常分支血管网形成为主要特征的眼底病变。吲哚菁绿眼底血管造影（ICGA）是其诊断金标准。OCTA在PCV中的应用也得到广泛关注，但是由于对OCTA中病灶的解读尚存在争议，不同研究中对PCV诊断的准确性差别较大，其临床应用也受到一定限制。随着近年来眼底影像学技术不断更新，OCTA达到更深的扫描层次，对血流信号的捕捉也愈加精准，其在PCV中的应用尤其是诊断准确性也得到一定程度提高。本文对OCTA在PCV中的应用和研究进展进行综述，以期为临床正确解读PCV患者的OCTA检查结果提供参考。n （中华眼科杂志，2020，56：950-955）“,”Optical coherence tomography angiography (OCTA) is a novel, non-invasive imaging technology, which could acquire volumetric angiographic information. Numerous studies have reported the potential clinical use of OCTA in a variety of common retinal disorders. Polypoidal choroidal vasculopathy (PCV) is characterized by the formation of branching choroidal vascular networks (BVN) with terminal dilatations (polyps). Indocyanine green angiography (ICGA) remains the golden diagnostic standard for PCV. The clinical application of OCTA in PCV is also widely investigated recent years. But the results are controversially interpreted. In addition to various diagnostic accuracy of PCV from different studies, the clinical application of OCTA in PCV is limited. With the constant innovation of fundus imaging techniques, OCTA is reaching greater investigation depth and become more accurate at picking up blood flow signals, which also improves the diagnostic accuracy of PCV. In this paper, we reviewed the clinical application and research progress of OCTA in PCV, in order to provide some assistant for clinical practice and correct interpretation of the reports. n (Chin J Ophthalmol, 2020, 56:950-955)
