方法：选取2016-01/12在我院治疗的PCV患者21例21眼，所有患眼均行ICGA检查，检查完后1h行OCTA检查。观察OCTA和ICGA图像特征情况。

结果：ICGA检查可见8眼有脉络膜异常分支血管网(BVN)，息肉样病变10眼，BVN合并息肉样病变2眼，无明显异常表现1眼； ICGA检查表现为BVN者8眼，在OCTA检查中均可见病变位置、范围及形态与ICGA相似的BVN表现； ICGA检查表现为息肉样病变者10眼，OCTA检查均表现为强信号亮点； ICGA检查表现为BVN合并息肉样病变者2眼，OCTA检查均可见BVN和对应部位的强信号亮点； ICGA检查无明显异常表现者1眼，在OCTA检查中同样无异常表现。

结论：PCV病变位置和形态在OCTA和ICGA中具有相似性，在ICGA检查受限的PCV中，OCTA或许在诊断中能发挥一定作用。

METHODS: Selected 21 patients 21 eyes with PCV in our hospital from January 2016 to December 2016. All the eyes were examined by ICGA, and was examined by OCTA after ICGA examination 1h. We observed the characteristics of OCTA and ICGA images.

RESULTS:ICGA examination showed that there were 8 cases of choroidal abnormal branch vascular network(BVN), polypoid lesions 10 eyes, BVN with polypoid lesions 2 eyes, no abnormal performance 1 eyes. OCTA examination showed 8 eyes of BVN, and the location, range and shape of BVN were similar to ICGA in OCTA examination. ICGA examination showed 10 cases of polypoid lesions. OCTA showed strong signal highlights. ICGA examination showed 2 cases of BVN complicated with polypoid lesions, and OCTA examination showed strong signal highlights of BVN and corresponding parts. ICGA examination showed no abnormal performance in 1 eyes, and no abnormal findings in OCTA examination.

CONCLUSION: OCTA and ICGA are similar in the location and morphology of PCV lesions, and OCTA may play a role in the diagnosis of PCV restricted ICGA.
