OCT Angiography: an Upcoming Non-invasive Tool for Diagnosis of Age-Related Macular Degeneration

Purpose: The purpose of this study was to review the most recent findings, characteristics, faults, and future perspectives of optical coherence tomography angiography (OCTA) in age-related macular degeneration (AMD). Recent Findings: In dry AMD, OCTA is useful on the evaluation of choriocapillaris perfusion and detection of naïve quiescent non-exudative choroidal neovascularization (CNV). In wet AMD, OCTA can provide detailed anatomic and morphologic information of CNVs, which may help to understand why and how they develop and become active. In other hand, the many artifacts present in OCTA images may lead to misinterpretation and misdiagnosis. Summary: OCTA is a still developing technology that is able to provide a large amount of anatomic, functional, and morphologic information in macular diseases and, particularly, AMD. As the technology evolves, the need of dye-based modalities tends to decrease. © 2017, Springer Science + Business Media New York.
