DIAGNOSTIC CHARACTERISTICS OF POLYPOIDAL CHOROIDAL VASCULOPATHY BASED ON B-SCAN SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AND ITS INTERRATER AGREEMENT COMPARED WITH INDOCYANINE GREEN ANGIOGRAPHY.

Abstract

PURPOSE

To examine the characteristics of polypoidal choroidal vasculopathy using B-scan optical coherence tomography angiography (OCTA), and determine the diagnostic criteria of polypoidal choroidal vasculopathy based on OCTA.

METHODS

This retrospective case series included patients diagnosed with treatment-naïve polypoidal choroidal vasculopathy who underwent indocyanine green angiography (ICGA) and swept-source OCTA at baseline. We compared the characteristics of the polyps detected using B-scan OCTA and ICGA. Then, the diagnostic concordance of each polypoidal lesion between ICGA and OCTA was evaluated.

RESULTS

Among 54 eyes of 52 patients, all 54 eyes showed flow signals indicating polyps on both ICGA and B-scan OCTA. All polyps on B-scan OCTA were detected as round/ring-like flow signals inside pigment epithelial detachments, incomplete round/ring-like flow signals overlaid with round/ring-like OCT structures inside pigment epithelial detachments, or flow signals adjacent to a pigment epithelial detachment notch. Using B-scan OCTA, 94.7% of the polypoidal lesions were detected by an independent evaluator with an overall accuracy of 92.6% for counting the polypoidal lesions per eye relative to ICGA and a Kappa value of 0.82.

CONCLUSION

Polyp detection on B-scan OCTA demonstrates high accuracy and is comparable to that obtained on ICGA. B-scan OCTA could replace ICGA for the diagnosis of polypoidal choroidal vasculopathy.
