OCT Angiography-based Evaluation of the Choriocapillaris in Neovascular Age-related Macular Degeneration
Abstract Neovascular age-related macular degeneration (AMD) can lead to rapid, irreversible vision loss in untreated eyes.

| Summary: | Abstract Neovascular age-related macular degeneration (AMD) can lead to rapid, irreversible vision loss in untreated eyes. While the pathogenesis of neovascular AMD remains incompletely understood, the choriocapillaris has been hypothesized as the initial site of injury. Due to limitations of dye-based angiography, in vivo imaging of the choriocapillaris has been a longstanding challenge. However, the clinical introduction of optical coherence tomography angiography (OCTA) has enabled researchers and clinicians to noninvasively image the choriocapillaris vasculature, allowing the evaluation of the choriocapillaris in eyes with a variety of pathologies. In this perspective, we review important OCTA-based findings regarding choriocapillaris impairment in neovascular AMD and discuss limitations and future directions of OCTA technologies in the context of this disease. |
