Sensitivity, Specificity, and Limitations of Optical Coherence Tomography Angiography in Diagnosis of Polypoidal Choroidal Vasculopathy

Figure 5

Clinical diagnosis of idiopathic polypoidal choroidal vasculopathy (PCV) in age-related macular degeneration (AMD) with optical coherence tomography angiography (OCTA). If the patient is suspected of having idiopathic polypoidal choroidal vasculopathy (PCV), OCTA is the next exam. With obvious branching vascular nets (BVNs) in OCTA, further polyp detection is the next sign for a diagnosis of PCV; if not, further indocyanine green angiography (ICGA) is required for cases without BVNs or further polyps in OCTA. FA: fluorescein angiography; PEDs: pigment epithelial detachments; SD-OCT: spectral-domain optical coherence tomography.
