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

Figure 3

Occult choroidal neovascularization (occult CNV) could be misdiagnosed as idiopathic polypoidal choroidal vasculopathy by optical coherence tomography angiography (OCTA). Color fundus image showed a retinal hemorrhage (a), and fluorescein angiography showed an occult CNV leakage pattern (b). OCTA revealed a branching vascular net-like shape (arrows) (c). However, indocyanine green angiography did not detect any polyps (d).
