PURPOSE: To study the efficacy of swept source optical coherence tomography angiography (SSOCTA) to longitudinally follow-up patients with extrafoveal polyps post-laser photocoagulation and anti-vascular endothelial growth factor injection.
METHODS: Observational case series. Four patients diagnosed as polypoidal choroidal vasculopathy with extrafoveal polyps on multimodal imaging were followed up serially on SSOCT, en face and cross-sectional SSOCTA at a month and then 3 monthly for a year. Indocyanine green angiography was repeated at 4 months and 1 year.
RESULTS: Anatomical regression of extrafoveal polyps was documented on a combination of en face and cross-sectional SSOCTA, 3 months post-laser photocoagulation and anti-vascular endothelial growth factor. Regression of polyps was maintained at the 12-month follow-up visit in all cases. Changes in branching vascular network morphology post-treatment were well-delineated on en face SSOCTA. Swept source optical coherence tomography angiography findings correlated well with the gold standard indocyanine green angiography.
CONCLUSION: Swept source optical coherence tomography angiography is an effective noninvasive imaging modality to diagnose and longitudinally follow-up extrafoveal polyps postintervention. Laser photocoagulation with anti-vascular endothelial growth factor achieved regression of polyps in all cases and this was maintained over 12 months.
