En face swept-source optical coherence tomography angiography choroidal vasculography (CVG) a tool to discriminate choroidal abnormalities in polypoidal choroidal vasculopathy

BACKGROUND Swept source optical coherence tomography angiography (SS-OCT-A) choroidal vasculography (CVG) is an imaging method which allows the evaluation of deep choroid details, being a promising too in choroidal pathologies as polypoidal choroidal vasculopathy (PCV). RESEARCH DESIGN AND METHODS Cross-sectional study performed at FOSCAL International Clinic in Colombia. CVG features in patients with PCV were evaluated using SS-OCT CVG. RESULTS Twenty-two eyes of 21 patients were included. The mean age was 72.7 ± 6.5 years old (range: 48.6-95.4 years old). Twelve (57.1%) patients were male. The mean number of polyps detected by SS-OCT-A CVG before treatment with anti-VEGF therapy was 2.04 ± 1.18, which decreased after treatment to 1.18 ± 0.71. This result was statistically significant (p
