CHARACTERIZATION AND DIFFERENTIATION OF POLYPOIDAL CHOROIDAL VASCULOPATHY USING SWEPT SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY.

Journal Article

To determine the correlation and agreement between swept-source optical coherence tomography angiography (SS-OCT-A) with fluorescein angiography (FA), indocyanine green angiography (ICGA) and spectral domain OCT (SD-OCT) in characterizing polypoidal choroidal vasculopathy (PCV) and in differentiating eyes with typical age-related macular degeneration (t-AMD).This study included 32 and 54 eyes with t-AMD and PCV, respectively, who underwent SS-OCT-A, SD-OCT, fluorescein angiography, and indocyanine green angiography. The images from these four techniques were compared.On SS-OCT-A, flow signals with vascular network configuration were detected in 81.2% and 77.8% of eyes with t-AMD and PCV, respectively. 40.4% of polyps were detected as flow signals with polypoidal configuration. Compared with indocyanine green angiography, SS-OCT-A had sensitivity and specificity of 83.0% and 57.1%, respectively, for vascular network, and 40.5% and 66.7% for polyps. Longitudinal changes were in agreement between SS-OCT-A and SD-OCT in 90% of eyes. 88.2% of eyes with dry retina on SD-OCT had persistent vascular net on SS-OCT-A. In two cases with reactivation of PCV, SS-OCT-A was more sensitive at detecting recurrence than SD-OCT.Swept-source optical coherence tomography angiography is effective at detecting vascular network that correlate to conventional angiography in eyes with t-AMD and PCV. Swept-source optical coherence tomography angiography is inferior to indocyanine green angiography in detecting polyps and cannot replace indocyanine green angiography for differentiating PCV from t-AMD; however, SS-OCT-A may be more sensitive than SD-OCT in detecting early recurrence.
