Optical coherence tomography (OCT) system maker Optovue (Fremont, CA) now offers higher-density OCT angiography (OCTA) imaging that improves resolution and peripheral visualization of vasculature in the eye. AngioVueHD Imaging provides OCTA scans with 73% more sampling points than the company's current AngioVue 6 × 6 mm scan, and improves image resolution by approximately 33% over the existing field of view. This enables physicians to more closely assess the fine vasculature in the eye for changes that could indicate ocular disease.

One of the major challenges of OCTA imaging is the limited region of the eye that can be visualized for assessing fine microvasculature. Currently, the standard field of view for the best image quality measures 3 × 3 mm. The feedback from early clinical evaluators of the AngioVueHD enhancements suggests the new 6 × 6 mm OCTA scan enables the improved likelihood of detecting abnormalities and assessing fine microvasculature details that would typically extend beyond the central 3 × 3 mm region.
The company also released AngioVueHD Montage, which automatically combines two high-density images—one at the central macular region (the portion of the retina responsible for central, high-resolution color vision that is possible in good light), and the other centered at the optic disc (the entry point for the major blood vessels that supply the retina)—in a 10 × 6 mm field of view. The ability to automatically create the montage is useful for imaging vasculature in potential pathologies that may extend into the periphery of the imaging plane.
AngioVueHD will be highlighted at three upcoming annual meetings: Vision Source, to take place May 4-6, 2017, in Nashville, TN (booth #202); ASCRS, to be held May 6-8, 2017, in Los Angeles, CA (booth #1215); and ARVO, scheduled for May 7-10, 2017, in Baltimore, MD (booth #3612).
