Optical Coherence Tomography Angiography, or OCTA, is new, non-invasive approach to visualizing retinal vasculature that is transforming the way physicians see retinal and choroidal vasculature.
OCTA produces ultra-high resolution, three-dimensional images that are displayed as individual layers of retinal vasculature, allowing you to isolate specific areas of interest and see microvasculature that is not easily seen with FA or ICGA. New high-density OCTA imaging produces larger format scans with outstanding image quality to enable assessment with a wider field of view. And Because OCTA is derived from OCT data, you'll see widefield structural OCT images, such as B-scans and thickness maps, right alongside the OCTA images, all from a single imaging system.
OCTA image acquisition requires less time than a dye-based procedure and does not require preplanning. As with OCT B-scans, and unlike FA, it can be accomplished by a trained technician to improve the workflow of your busy practice.
OCTA allows frequent imaging, so you can assess the vasculature as frequently as you would perform an OCT B-scan to assess structural changes.

The AngioVue Imaging System, installed in more than 850 ophthalmic practices worldwide, brings valuable new information to your clinical practice. For the first time, you can view individual layers of retinal vasculature, non-invasively, to isolate specific areas of interest and reveal microvasculature that is not easily seen with traditional angiographic techniques.
