• PurposeTo compare optical coherence tomographic angiography (OCTA) and indocyanine green angiography (ICGA) images for detecting polypoidal lesions (PLs) and branching vascular networks (BVNs), and to measure the polypoidal areas (PAs) in patients with polypoidal choroidal vasculopathy (PCV).MethodsAll patients underwent ICGA, optical coherence tomography (OCT), and OCTA. We compared the detection sensitivity for PL and BVN, as evaluated by the ICGA and OCTA images. Furthermore, PA measured by ICGA was divided into two groups: one in which the area could be measured by OCTA (ICGA OCTA ) and the other in which the area could not be measured by OCTA (ICGA OCTA ).ResultsTwenty-one consecutive eyes of 21 patients (mean age, 73.8±9.8 years) were included. ICGA detected PL in all eyes (100%), whereas OCTA detected PL in 16 eyes (75.2%); ICGA detected BVN in 15 eyes (71.4%), whereas OCTA detected BVN in 20 eyes (95.2%). The mean PA in ICGA OCTA and ICGA OCTA was 0.24±0.04 and 0.14±0.01 mm , respectively; a significant difference was observed between ICGA OCTA PA and ICGA OCTA PA (P<0.0001). In addition, the mean PA in the ICGA OCTA group measured by ICGA and OCTA was 0.24±0.04 was 0.19±0.04 mm , respectively; these values were significantly different (P=0.0046).ConclusionsOCTA might detect more BVNs and fewer PLs compared with ICGA, and PL detected by OCTA might be smaller than those detected by ICGA.
