Abstract:
AIM: To observe of optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) image feature in polypoidal choroidal vasculopathy (PCV).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.
