En Face Spectral-Domain Optical Coherence Tomography for the Diagnosis and Evaluation of Polypoidal Choroidal Vasculopathy.

Abstract

To evaluate the diagnostic capability of en face spectral-domain optical coherence tomography (SD-OCT) in patients with polypoidal choroidal vasculopathy (PCV) diagnosed by indocyanine green angiography (ICGA). A retrospective, consecutive case series of 100 eyes diagnosed with PCV by ICGA were imaged with en face SD-OCT. Evaluation of the PCV complex on en face SD-OCT was performed on the ability to diagnose PCV by the characteristic configuration of the PCV complex and the extent and size of the PCV lesion. The PCV complex was better visualized on ICGA in 45 eyes, on en face SD-OCT in 44 eyes, and equally well in 11 eyes. The extent of the PCV complex was larger on en face SD-OCT in 65 eyes, larger on ICGA in 23 eyes, and equal in size in 12 eyes. En face SD-OCT images the characteristic findings of PCV and provides a noninvasive way to diagnose and treat PCV when ICGA is not available. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:737-744.].
