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

Figure 1

Two steps of multimodal evaluation of an example. In the first step, one color picture of the macula (top left), early (top right), mid, and late phases (the second row, left to right) of fluorescein angiography, and spectral-domain optical coherence tomography images (the third row) of all cases were given to the two graders. In the second step, the optical coherence tomography angiography (OCTA) images including four images at the superficial retina, deep retina, outer retina, and choriocapillary level were provided (the fourth to sixth rows). The two graders then made a diagnosis of polypoidal choroidal vasculopathy (PCV) or non-PCV in each step.
