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

Figure 4

True-positive case of polypoidal choroidal vasculopathy (PCV). Subretinal orange nodules in a color image (arrow) (a), localized pigment epithelial detachments (PEDs) with delayed leakage of an occult choroidal neovascularization pattern in fluorescein angiography, (b) and subretinal fluid in spectral-domain optical coherence tomography (c) were noted. Optical coherence tomography angiography showed branching vascular nets (arrows) with surrounding PEDs at a choroidal level, but no significant polyps (d). Indocyanine green angiography confirmed polyps beneath the PEDs (arrow) and the diagnosis of PCV (e).
