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.
Approximately one in five fellow eyes with unilateral tAMD and PCV have features of nonexudative neovascularization. The use of multimodal imaging including ICGA and OCT-A can identify these features. The presence of pachychoroid epitheliopathy should alert clinicians to the possibility of underlying neovascularization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
