      Identification and Characterization of Imaging Technique Errors and Artifacts using Anterior Segment Optical Coherence Tomography for Irido-Corneal Angle Evaluations in Glaucom
      Purpose Anterior segment optical coherence tomography (ASOCT) platforms provide non-invasive and quantifiable evaluations of anterior chamber angle (ACA) anatomy. Even though these ACA measurements have been validated with high repeatability and reproducibility, we are the first study to describe in detail the technique errors and artifacts that may occur during imaging of the ACA. The purpose of this study was to define the different types and quantify the frequency of ...

      Impact of segmentation density on spectral domain optical coherence tomography assessment in Stargardt disease
      Purpose Automated spectral domain optical coherence tomography (SD-OCT) segmentation algorithms currently do not perform well in segmenting individual intraretinal layers in eyes with Stargardt disease (STGD). We compared selective B-scan segmentation strategies for generating mean retinal layer thickness and preserved area data from SD-OCT scans in patients with STGD1. Methods Forty-five eyes from 40 Stargardt patients were randomly selected from the ongoing Natural History of the Progression of Atrophy Secondary ...

      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.
