      Appearance of pediatric choroidal neovascular membranes on optical coherence tomography angiography
      Purpose Compared with fluorescein angiography (FA), the gold standard for diagnosing choroidal neovascularization (CNV) activity, optical coherence tomography angiography (OCTA) is non-invasive without risks associated with fluorescein dye use, and may be especially advantageous in the diagnosis and monitoring of children with CNV. Methods Eight eyes from eight patients aged 12 months to 18 years were imaged with the investigational Spectralis OCTA (version 6.9, Heidelberg Engineering, Heidelberg, Germany) and ...

      Best Clinical Practice for Age-Related Macular Degeneration Imaging
      Purpose: To identify best clinical practices for macular degeneration imaging. Methods: We reviewed best clinical practices for imaging patients with age-related macular degeneration. These recommendations are based on different levels of evidence (I-III). Results: The type of imaging needed depends to some degree on the clinical scenario: first visit vs follow-up visit vs poorly responsive patient. Conclusions: Imaging technologies that may be useful include optical coherence tomography, fundus photography, fundus ...

      Depth-Based, Motion-Stabilized Colorization of Microscope-Integrated Optical Coherence Tomography Volumes for Microscope-Independent Microsurgery
      Purpose : We develop and assess the impact of depth-based, motion-stabilized colorization (color) of microscope-integrated optical coherence tomography (MIOCT) volumes on microsurgical performance and ability to interpret surgical volumes. Methods : Color was applied in real-time as gradients indicating axial position and stabilized based on calculated center of mass. In a test comparing colorization versus grayscale visualizations of prerecorded intraoperative volumes from human surgery, ophthalmologists ( N = 7) were asked to identify retinal ...

    4. One benefit of SD-OCT is the creation of the summed voxel projection [SVP], which is helpful for orientation of individual OCT scans. One can collapse three-dimensional OCT volumes along the depth axis to form a two-dimensional plane, summing pixels to calculate one representative pixel intensity alone each line in the projection.
