Purpose   To examine choroidal neovascularization (CNV) characteristics in patients with exudative age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV), using swept-source optical coherence tomography angiography (SS-OCTA), and investigate agreement with OCT B-scan, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) by two different examiners.Methods   This is a retrospective multicentric study that involved patients with a history of AMD and PCV.  Examiner A , who had access to OCTA, B-scan OCT, FFA, and ICGA imaging, had to differentiate between AMD and PCV, study the activity of AMD using Coscas' criteria (active vs. quiescent), and categorize PCV subtypes, while  examiner B  had only access to OCTA. Then, the diagnostic concordance was assessed between both examiners.Results   A total of 27 patients (11 females (40.7%) and 16 males (59.3%),  P  = 0.231) were included in the analysis. Among those, 13 patients presented with neovascular AMD and 14 patients with PCV. There were 92.3% of correct answers regarding appropriate diagnosis and lesion characterization among AMD patients, against 61.5% of correct answers among PCV patients. The overall interrater reliability agreement between examiners, using Cohen's kappa coefficient ( κ ) was 0.70 (0.5082-0.8916). Disagreement was found with  one active AMD  misdiagnosed as inactive AMD,  three inactive PCV  misdiagnosed as inactive AMD, and  one inactive PCV  misdiagnosed as active AMD.Conclusion   SS-OCTA alone remains limited in some specific phenotypes of PCV, which suggests the ongoing role of B-scan OCT associated with FFA and ICGA in the diagnosis of these conditions.
