      Distinct Retinal Capillary Plexuses in Normal Eyes as Observed in Optical Coherence Tomography Angiography Axial Profile Analysis
      Optical coherence tomography angiography (OCTA) allows the retinal microvasculature to be visualized at various retinal depths. Previous studies introduced OCTA axial profile analysis and showed regional variations in the number and location of axially distinct vascular retinal plexuses. OCTA acquisition and processing approaches, however, vary in terms of their resulting transverse and axial resolutions, and especially the latter could potentially influence the profile analysis results. Our study imaged normal eyes ...

    1. With CIRRUS FastTrac, I can place a highest resolution 20x B-Scan precisely on the area I am treating at each successive visit to see the fine details of the patient’s response to treatment...It’s also very helpful for removing any eye motion from the larger cube scans without disturbing my patient flow because it works so quickly. My initial experience is that FastTrac is about 30 percent faster than other tracking methods I have used.
