New Concepts in Polypoidal Choroidal Vasculopathy Imaging: A Focus on Optical Coherence Tomography and Optical Coherence Tomography Angiography.

Polypoidal choroidal vasculopathy (PCV) is a variant of neovascular age-related macular degeneration. It is characterized by polypoidal dilatations at the terminus of branching vascular network located beneath the retinal pigment epithelium. These polypoidal lesions are best visualized on indocyanine green angiography. With recent advances in ocular imaging, optical coherence tomography (OCT) and OCT angiography (OCTA) have been increasingly used to aid in the diagnosis and monitoring of treatment responses in PCV. This review provides a summary of the current status of various imaging modalities in PCV, with special focus on OCT and OCTA.
